In this study, we estimated the performance of PEMFC as changing operating temperature in different inlet humidity condition at cathode side but anode dry, and tried to match experimental results with 1-dimensional simulation to construct database for advanced computation model. We used Nafion 112 membrane and a self-manufactured PEMFC with 25cm{sup}2 active area was used. The range of operating temperature was 40～70°C and oxygen through bubbled humidity chamber was supplied 0～80% humidity condition as changing water temperature in humidity chamber. For figuring out governing equations express water contents in electrolyte membrane, the linear forward difference method was applied about time progress and quadratic central difference method was used about space progress. In low operating temperature condition, 40～60°C, increasing temperature rarely effected cell performance but we can see performance drop at 70°C.By modifying Henrry's constant and/or diffusion coefficient, the modified one-dimensional model was accomplished for calculation.
