Abstract

The effect of changing operation temperature and H₂ and O₂ concentration in supply gas on the i-V characteristic of a small PEFC was examined experimentally. Cell performance was found to decrease with decrease in H₂ and O₂ concentrations and the influence of O₂ concentration was larger than that of H₂. When the relative humidity of the supply gas at both anode and cathode was 100%, no influence of operation temperature could be found. Furthermore, a model was created that can express these influences on PEFC reaction characteristics. Combination of these model equations with gas flow analysis allows the reaction characteristics to be examined in an actual scale PEFC.
