Abstrakt: This study presents the effect of cathode channel design with vary cross-sectional area and aspect ratio. Three dimensional, steady state, single phase and isothermal model is developed to investigate the effect of cross-sectional area and aspect ratio of cathode flow channel on the cell performance for open-cathode PEM fuel cell. The result shows that increasing of cross-sectional area lead to the decreasing of molar concentration of oxygen at the interface of gas diffusion layer and catalyst layer that then decrease cell performance. On the other hand, increasing aspect ratio lead to the increasing of the molar concentration of oxygen and cell performance. [ABSTRACT FROM AUTHOR]
