概要 In order to improve the output performance of PEFC, the liquid water has to be removed smoothly from GDL because it prevents gas diffusion. In this study, the relationship between the liquid water dis...tribution and operating condition of fuel cell was examined by experiments with visualized cell and numerical analysis. As a result, it was found that the position and the amount of the liquid water in porous media made a great impact on the output performance. In the case of high temperature but low humidity operating condition, liquid water accumulated near Rib side and caused higher performance.続きを見る
