Abstract

Conventional fuel cell can generate DC power and water by react hydrogen and oxygen, while electrolyzer function reversely by splitting water to hydrogen and oxygen with the assist of external power source mostly from renewable resources such as solar and wind. The unitized regenerative fuel cell (URFC) is a unique cell can function as fuel cell and electrolyzer within same cell at different modes. In contrast to conventional Fuel cell the URFC membrane catalyst need a delicate choosing because the highly performance catalyst for electrolysis may function poorly at fuel cell mode and vice versa. Selecting the URFC catalysts need a delicate compromise. In this study a single cell URFC was assembled, the catalysts for the membrane electrode assembly was Ru with loading rate of 1.25 mg/cm2 for oxygen side and Pt with loading rating of 1 mg/cm2. The results gained from the study show a satisfactory performance for both electrolyzer and fuel cell mode and the required voltage for water splitting through the electrolyzer mode increased significantly with increasing the operating current and leads to increase the amount of hydrogen generated. For fuel cell mode, the output voltage decreases when the operating current increasing.
