Since the heat transfer characteristics in Polymer Electrolyte Fuel Cell (PEFC) influences its power generation performance, this study clarifies the temperature characteristics to in-plane direction in single PEFC. In addition, since we expect the heat and mass transfer as well as power generation characteristic are enhanced by decreasing PEM and GDL’s thicknesses, it is effective to investigate the impact of components thickness on them under high temperature operation. This study aims to clarify how to influence PEM and GDL’s thicknesses on not only heat and mass transfer characteristics but also power generation characteristic under high temperature, e.g., 90 °. The present study measured temperature distributions to in-plane direction on cathode separator back of cell by thermograph with power generation changing initial operation temperature as well as relative humidity of inflow gases. As a result, the increase in generated power and the even temperature distribution were obtained due to the decrease in GDL’s thickness. Since the moisture transfer was promoted with decreasing the thickness of PEM, the power generation performance was improved. It was clarified that the impact of GDL’s thickness was larger than that of PEM’s thickness.
