Optimalizace inicializační sekvence PEM palivového článku ; Optimalization of initial sequence of PEM fuel cell

Abstract

Tato bakalářská práce se zabývá PEM články a optimalizací jejich iniciační sekvence. Práce obsahuje stručnou historii článků, jejich druhy, bližší popis funkce PEM článku a jeho částí. Následně je podrobněji popsán článek, který je zkoumán v tomto experimentu. Jsou zde stanoveny faktory ovlivňující chod a především náběh článku. Tyto faktory jsou dále ověřeny měřením závislosti doby náběhu na předešlé odstávce a dalších termodynamických parametrech. Výsledky jsou zhodnoceny a v závislosti na nich je sestaven návrh optimální iniciační sekvence PEM článku. ; Obhájeno ; This bachelor thesis deals with the hydrogen PEM fuel cells and with the optimalization of their initial sequence. The thesis contains a brief history of fuel cells in general, types of fuel cells and detailed description of basic functional principles and structure of the PEM fuel cell. Subsequently the particular PEM fuel cell which is examined in this experiment is also thoroughly described. Factors which affect the functionality and especially the starting sequence are stated. After that, these factors are confirmed by measuring the dependence of the starting sequence time on previous inactive time period and other thermo dynamical parameters. The results are subsequently evaluated and with respect to them, the optimal initial sequence design is drawn up.
