description Publicationkeyboard_double_arrow_right Doctoral thesis 2019 FrancePublisher:HAL CCSD Authors: Filimonenkov, Ivan;L’étude de l'électrocatalyse des réactions de réduction de l'oxygène (RRO) et de dégagement de l'oxygène (RDO) est étroitement reliée au développement de matériaux cathodiques et anodiques pour les piles à combustible et les électrolyseurs. L’objectif de cette thèse est de développer et d’étudier des matériaux d’électrodes à base d’oxydes de Mn et de Co, actifs et stables, à la fois pour la RRO et la RDO. Les relations entre les caractéristiques électrochimiques des compositions pérovskite / carbone et les propriétés de leurs composants sont établies et étayées expérimentalement dans la thèse. Il a été constaté que la résistance des matériaux carbonés à la corrosion dans les conditions de la RDO est influencée non seulement par leur ordre cristallin, mais également par leur activité intrinsèque pour la RDO. Il a été démontré que les activités des pérovskites à base de Mn et de Co dépendent linéairement du nombre de cations de Mn et de Co rechargeables, respectivement pour la RRO et la RDO. Il a été découvert qu'une intercalation réversible de l'oxygène dans la structure cristalline des pérovskites à base de Co se produit dans les conditions de la RDO, ainsi qu'à des potentiels plus faibles. A study of electrocatalysis of oxygen reduction (ORR) and oxygen evolution (OER) reactions is closely related with a development of cathodic and anodic materials for fuel cells and elec-trolyzers. An objective of this thesis is to develop and investigate Mn, Co-oxide-based elec-trode materials active and stable in both the ORR and OER. Relationships between electro-chemical characteristics of perovskite/carbon compositions and properties of their compo-nents are stated and experimentally substantiated in the thesis. It is found a corrosion re-sistance of carbon materials under OER conditions is influenced not only by their crystalline order, but also by their intrinsic OER activity. It is shown the ORR and OER activity of Mn, Co-based perovskites linearly depends on the number of rechargeable Mn and Co cations, respectively. It is revealed a reversible oxygen intercalation through a crystal structure of Co-based perovskites occurs under OER conditions as well as at lower potentials.

In such a situation, it is necessary to involve model reanalysis and satellite altimetry data that ensure the regular coverage of the whole West Siberian Plain, making it possible to supplement field studies and to considerably expand the area of research. This determines the relevance of the thesis. Chapter 1 describes the physic and geographic factors that determined the evolution of the West Siberian Plain; chapter 2 is devoted to methods used in the study; the analysis of trends of air temperature and precipitation is presented in the 3rd chapter as well as the estimation of temporal variability of moisture regime of watersheds from satellite altimetry. The originality of the thesis is to apply satellite altimetry data for estimation of spatiotemporal variability of flooded zones based on the analysis of a reflected signal. ; Le caractère fortement marécageux du territoire de la Sibérie Occidentale et la rareté des stations d'observations hydrométéorologiques compliquent le suivi du régime hydrologique des bassins versants. Dans une telle situation, la prise en compte des données de ré-analyse météorologique et d'altimétrie satellitaires, assurant une couverture régulière de l'ensemble du territoire étudié, permet de compléter les observations in situ et d'élargir considérablement la portée des recherches, ce qui détermine la pertinence de ce travail. Le premier chapitre décrit les principaux facteurs physiques et géographiques qui ont déterminé le développement de la zone d'étude ; le deuxième chapitre est consacré aux méthodes d'étude; le troisième chapitre présente les résultats d'analyse de la variabilité des caractéristiques climatiques et hydrologiques dans les bassins fluviaux. L'originalité de cette thèse est d'appliquer une nouvelle approche de la quantité d'eau de la zone étudiée.
