This paper covers our investigation into a decline in FC productivity resulting from hydrogen fuel containing CO. Here, we had several investigations into CO poisoning on dependence of the type of catalyst electrodes between Pt and Pt+Ru alloy. The results are summarized as follows: 1) The actual process of poisoning was scrutinized by focusing on adsorption of CO molecules. 2) The investigation into the relationship between the CO concentration and the poisoning was carried out. If the FC underwent at a high CO concentration, no significant improvement could be expected by operating at increased pressure. The effect of the operating temperature is almost the same between two types of FCs. 3) Some formulas to predict the performance were derived theoretically and empirically.
