Contribution à la modélisation tridimensionnelle du comportement termo fluidique d'une cellule de pile à combustible à membrane échangeuse de protons

Abstract : The fuel cell systems are integrated into a set of auxiliary constraints that are operating them. To consider a good performance, it is necessary to better control these aids in eliminating the maximum such constraints. Modeling is increasingly considered to provide an answer. Among these different types of models, there is that which is to treat the problem of water management, the main cause of flooding of sites reactive electrodes batteries. Such an approach can not be done without difficulty because it requires the coupling of several equations. By using a CFD code FLUENT, we deal in a real configuration of a type of model that can enable us to provide an answer to the problem of water status of the cell. This consists of determining some parameters of transfer at he heart of the battery as the cell temperature, relative humidity, partial pressures and the molar flow components.
