The performance of PEMFC is known to be influenced by different operating conditions such as temperature, pressure, and humidification of the reactant gases. Especially, the humidification is essential for performance enhancement of the PEMFC because proton conductivity depends on hydration of the membrane. In this study, the visualization experiment is in order to verify dew condensation in channel of PEMFC. As the results, the dew condensation was verified through visualization experiment on the temperature variation. These problems, such as precise control of the dew condensation were resolved by supplying low humidity reactant gas.
