Validation expérimentale d'outils de modélisation d'une pile à combustible de type PEM :

Abstract : In this work, a global view of the phenomena occurring in a PEM fuel cell is given. An original methodology was developed in order to determine the main parameters : thermodynamics, kinetics and transport phenomena. The gas flow in bipolar plates was chracterised using experimental determination of residence time distributions and numerical simulations. Kinetics of both electrochemical reactions were analysed feeding the cell by diluted gases. In this part, the diffusion of reactants in the membrane electrodes assembly was taken into account. Finally, the relationship between humidity and electrical performance was investigated and the ohmic resistance of the cell was estimated
