description Publicationkeyboard_double_arrow_right Article , Journal 2004 FrancePublisher:Elsevier BV Authors: Gabrielli, Claude; Mocoteguy, Philippe; Perrot, Hubert; Wiart, Robert;The mechanism of copper deposition in a sulphuric acid–sulfate bath in the presence of chlorides was investigated by electrochemical impedance measurements. A model where the chloride ions added to a sulphuric acid–sulfate copper-plating bath have a catalytic action not limited by mass transport has been proposed. This shows that the observed mass transport limitation is due to the diffusion of cupric ions and that, at high current densities, the copper deposition is mainly due to a mechanism involving CuCl formation on the electrode.

Electroacoustic admittance measurements were performed on copper bath solutions containing additives that are used in the copper damascene process. Preliminary results have shown that an electroacoustic admittance parameter can be defined that varies with additive concentration. It is proposed that quartz resonators may be suitable sensors for monitoring copper bath additives.

Electrochemical impedance measurements were performed on copper bath solutions during copper deposition and subsequent aging of the bath. The results show a correlation between the low-frequency capacitive loop of the electrochemical impedance and copper deposit roughness. The deposit became smoother as the bath aged and reached an optimal value, after which the deposit became rougher. The optimal surface smoothness correlated with a minimum in the low-frequency capacitive loop diameter of the impedance. The results suggest that electrochemical impedance measurements may be used to monitor changes in the copper bath that affect copper deposit quality and superfilling capability.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2016 FrancePublisher:Elsevier BV Authors: Philippe Moçotéguy; Bastian Ludwig; Nadia Yousfi Steiner;Abstract We apply a 2 5−1 fractional factorial Design of Experiments (DoE) test plan in order to discriminate the direct effects and interactions of five factors on the water management of a 500 We PEMFC stack. The stack is submitted to current steps between different operating levels and several responses are extracted for the DoE analysis. A strong ageing effect on stack and cell performances is observed. Therefore, in order to perform the DoE analysis, responses which values are too strongly affected by ageing are “corrected” prior to the analysis. A “virtual” stack, considered as “healthy”, is also “reconstructed” by “putting in series” the cells exhibiting very low performance drop. The results show that stacks and cells' resistivities are mostly impacted by direct effects of both temperature and cathodic inlet relative humidity and by compensating interaction between temperature and anodic overstoichiometric ratio. It also appears that two responses are able to distinguish a “healthy” stack from a degraded stack: heterogeneities in cell voltages and cell resistivities distributions. They are differently impacted by considered effects and interactions. Thus, a customised water management strategy could be developed, depending on the stack's state of health to maintain it in the best possible operating conditions.

Moçotéguy;Abstract In this study, a 500 We 19 cells Proton exchange membrane fuel cell (PEMFC) stack was aged for ∼1200 h and submitted to current steps between different operating levels. Using two different multi-channel data acquisition systems (one at 100 kHz and one at 1 Hz). the evolution with ageing of individual cells and full stack's short term (∼10 s) and medium term (∼4 min) dynamic performances was followed. Undershoots and overshoots behaviours were observed for respective current step-up and step-down. It appeared that, in studied operating conditions, the first time constant was related to the charge transfer at electrode/electrolyte interfaces. After the first “plateau”, the voltage evolution was explained by a membrane water content evolution. With the very fast data acquisition system, the evolutions of stack and individual cells' electrochemical characteristics (ohmic resistivities, charge transfer time constant) were also followed. Except for one cell which ohmic resistivity increases and which performance strongly decreases at the end of ageing, ageing doesn't affect the resistivities. Moreover, except for start-up step, no influence of step level was observed on ohmic resistivities. The higher resistivity obtained at start-up was attributed to the initiation of membrane drying related to an interruption of water production while gases still flow. Besides, the charge transfer time constant remains unaffected by ageing or step level.

Thanks to an in-lab test bench used for the experimental tests, various parameters can be recorded as electrical or fluidic measurements. The chosen input signal for the diagnosis uses no additional expensive and no intrusive sensors specifically dedicated for the diagnosis task. It uses insofar only the already existing sensors on the system. This paper focuses on the detection and identification of a high air stoichiometry (HAS) fault. The wavelet transform (WT) and more precisely the energy contained in each detail of the wavelet decomposition is used to diagnose quickly an oversupply of air to the fuel cell system. Finally, some experimental results are presented according to different input signals, in order to prove the efficiency of the patented method.

Electrochemical impedance spectroscopy and cyclic voltammetry were used to characterize the aging of copper plating baths used in damascene process for superfilling of trenches and vias in the semiconductor industry. The effects of copper anode composition, anodic current density, and accelerator nature and concentration were studied. Phosphorus added to copper anodes has a prominent impact on the evolution of current/voltage curves and impedance spectra during bath aging. The observed evolutions were explained by the formation of a -accelerator complex in the bulk of the bath that adsorbs at the copper surface to act as an accelerating species, and by the increase of its concentration during aging with undoped copper anode. The -accelerator complex formation is limited by the phosphorus contained in the Cu-P anode, which traps electrogenerated cuprous ions in the black anodic film. Differences observed between baths containing SPS (bis(3-sulfopropyl)disulfide) or MPSA[(3-mercaptopropane)sulfonic acid] are also attributed to the existence of two different -accelerator complexes, both of which exhibit different formation equilibrium constants.

The chemistry of this bath contained, in addition to sulphuric acid, copper sulphate and chloride ions, polyethylene glycol (PEG) as an inhibitor and 3-mercapto-1-propanesulfonate, sodium salt (MPSA) as an accelerator. The experimental results were compared with a model taking into account these organic additives. A competitive adsorption of two complexes: PEG–Cl–CuI and CuISPS formed from Cu+ and the additives, is proposed. A good agreement was shown between this model and the experiments on fresh plating bathes.

Its performances in “fresh” and “aged” state have been compared. The cells exhibited two different response times: the first one at about 40 ms, corresponding to the time needed to charge the double-layer capacitance, and the second one at about 15–20 s. The first time response was not affected by the ageing process, despite the decrease of the performances, while the second one was. Our simulations indicated that a high amount of liquid water was present in the stack, even in “fresh” state. This liquid water is at the origin of the performances decrease with ageing, due to its effect on decreasing the actual GDL porosity that in turn cause the starving of the active layer with oxygen. As a consequence, it appears that water management issue in a fuel cell operating in dead-end mode at room temperature mainly consists in avoiding pore flooding instead of providing enough water to maintain membrane conductivity.

A model where the chloride ions added to a sulphuric acid–sulfate copper-plating bath have a catalytic action not limited by mass transport has been proposed. This shows that the observed mass transport limitation is due to the diffusion of cupric ions and that, at high current densities, the copper deposition is mainly due to a mechanism involving CuCl formation on the electrode.

Electroacoustic admittance measurements were performed on copper bath solutions containing additives that are used in the copper damascene process. Preliminary results have shown that an electroacoustic admittance parameter can be defined that varies with additive concentration. It is proposed that quartz resonators may be suitable sensors for monitoring copper bath additives.

Electrochemical impedance measurements were performed on copper bath solutions during copper deposition and subsequent aging of the bath. The results show a correlation between the low-frequency capacitive loop of the electrochemical impedance and copper deposit roughness. The deposit became smoother as the bath aged and reached an optimal value, after which the deposit became rougher. The optimal surface smoothness correlated with a minimum in the low-frequency capacitive loop diameter of the impedance. The results suggest that electrochemical impedance measurements may be used to monitor changes in the copper bath that affect copper deposit quality and superfilling capability.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2016 FrancePublisher:Elsevier BV Authors: Philippe Moçotéguy; Bastian Ludwig; Nadia Yousfi Steiner;Abstract We apply a 2 5−1 fractional factorial Design of Experiments (DoE) test plan in order to discriminate the direct effects and interactions of five factors on the water management of a 500 We PEMFC stack. The stack is submitted to current steps between different operating levels and several responses are extracted for the DoE analysis. A strong ageing effect on stack and cell performances is observed. Therefore, in order to perform the DoE analysis, responses which values are too strongly affected by ageing are “corrected” prior to the analysis. A “virtual” stack, considered as “healthy”, is also “reconstructed” by “putting in series” the cells exhibiting very low performance drop. The results show that stacks and cells' resistivities are mostly impacted by direct effects of both temperature and cathodic inlet relative humidity and by compensating interaction between temperature and anodic overstoichiometric ratio. It also appears that two responses are able to distinguish a “healthy” stack from a degraded stack: heterogeneities in cell voltages and cell resistivities distributions. They are differently impacted by considered effects and interactions. Thus, a customised water management strategy could be developed, depending on the stack's state of health to maintain it in the best possible operating conditions.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Journal 2014Publisher:Elsevier BV Authors: Nadia Yousfi Steiner; Bastian Ludwig; P. Moçotéguy;Abstract In this study, a 500 We 19 cells Proton exchange membrane fuel cell (PEMFC) stack was aged for ∼1200 h and submitted to current steps between different operating levels. Using two different multi-channel data acquisition systems (one at 100 kHz and one at 1 Hz). the evolution with ageing of individual cells and full stack's short term (∼10 s) and medium term (∼4 min) dynamic performances was followed. Undershoots and overshoots behaviours were observed for respective current step-up and step-down. It appeared that, in studied operating conditions, the first time constant was related to the charge transfer at electrode/electrolyte interfaces. After the first “plateau”, the voltage evolution was explained by a membrane water content evolution. With the very fast data acquisition system, the evolutions of stack and individual cells' electrochemical characteristics (ohmic resistivities, charge transfer time constant) were also followed. Except for one cell which ohmic resistivity increases and which performance strongly decreases at the end of ageing, ageing doesn't affect the resistivities. Moreover, except for start-up step, no influence of step level was observed on ohmic resistivities. The higher resistivity obtained at start-up was attributed to the initiation of membrane drying related to an interruption of water production while gases still flow. Besides, the charge transfer time constant remains unaffected by ageing or step level.

Electrochemical impedance spectroscopy and cyclic voltammetry were used to characterize the aging of copper plating baths used in damascene process for superfilling of trenches and vias in the semiconductor industry. The effects of copper anode composition, anodic current density, and accelerator nature and concentration were studied. Phosphorus added to copper anodes has a prominent impact on the evolution of current/voltage curves and impedance spectra during bath aging. The observed evolutions were explained by the formation of a -accelerator complex in the bulk of the bath that adsorbs at the copper surface to act as an accelerating species, and by the increase of its concentration during aging with undoped copper anode. The -accelerator complex formation is limited by the phosphorus contained in the Cu-P anode, which traps electrogenerated cuprous ions in the black anodic film. Differences observed between baths containing SPS (bis(3-sulfopropyl)disulfide) or MPSA[(3-mercaptopropane)sulfonic acid] are also attributed to the existence of two different -accelerator complexes, both of which exhibit different formation equilibrium constants.

The chemistry of this bath contained, in addition to sulphuric acid, copper sulphate and chloride ions, polyethylene glycol (PEG) as an inhibitor and 3-mercapto-1-propanesulfonate, sodium salt (MPSA) as an accelerator. The experimental results were compared with a model taking into account these organic additives. A competitive adsorption of two complexes: PEG–Cl–CuI and CuISPS formed from Cu+ and the additives, is proposed. A good agreement was shown between this model and the experiments on fresh plating bathes.

Its performances in “fresh” and “aged” state have been compared. The cells exhibited two different response times: the first one at about 40 ms, corresponding to the time needed to charge the double-layer capacitance, and the second one at about 15–20 s. The first time response was not affected by the ageing process, despite the decrease of the performances, while the second one was. Our simulations indicated that a high amount of liquid water was present in the stack, even in “fresh” state. This liquid water is at the origin of the performances decrease with ageing, due to its effect on decreasing the actual GDL porosity that in turn cause the starving of the active layer with oxygen. As a consequence, it appears that water management issue in a fuel cell operating in dead-end mode at room temperature mainly consists in avoiding pore flooding instead of providing enough water to maintain membrane conductivity.
