A unitized reversible fuel cell (URFC) which have both of function as water electrolyzer and fuel cell can be a main unit of hydrogen system. The Japan Automobile Research Institute (JARI) standard cell is modified to experiment URFC. The Gas Diffusion Layer (GDL) characteristics of O₂ side are considered for a better performance. The results of experiment show that an influence of Polytetrafluoroethylene (PTFE) on the O2 side GDL has not effect to water electrolyzer mode and has bad effect to fuel cell mode. The bigger Ti-felt fiber diameter has positive effect to the water exhaust and fuel cell mode performance.
