抄録

This paper shows an analysis of water transport phenomena in MEA in PEM electrolysis cell. In previous study, it was shown that the change of water transport pattern in diffusion layer and catalyst layer doesn't affect performance and Nafion membrane may be directly related to performance. In this study, a numerical analysis to clarify the water transport phenomena in MEA based on the experimental data (the amount of discharged water from the cathode and the impedance) was developed. The result showed that the effect of osmotic force on the water transport through the MEA is far larger than that of diffusion force and water content in Nafion membrane may increase as current density increases.
