According to the NEDO fuel cell/hydrogen technology development roadmap, high temperature condition over 90 ℃ is the target operating temperatures of PEFC systems (stationary and automotive) from 2020 to 2025. Power generation experiment using a single cell of PEFC was carried out at 90 ℃ and 100 ℃) using two types of PEMs and GDLs having different thicknesses. The power generation data was acquired by changing the presence/absence of MPL and the inflow gas flow rate/relative humidity. In addition, the temperature distribution on the back of separator was measured by a thermograph. Based on the obtained results, the effects of PEM and GDL thicknesses as well as MPL on various characteristics were discussed in this study.
