Polymer Electrolyte Fuel Cell (PEFC) is expected to be used in many fields as future power sources. Polymer electrolyte membrane, which is inserted in PEFC as a electrolyte, has proton conductivity that depends on its water content. It is important for improving the cell performance to keep suitable wet condition within the cell and grasp water concentration, diistribution, and its effect. It is said that the voltage response of PEFC is effected by condensed water, so in this study, we predicted the voltage response at the conditions with/without condensed water, and compared the results with experimental data. Both numerical and experimental results had relatively good agreement, and appropriateness of analytical model might be comfirmed.
