This paper covers our investigation into a decline in Fuel Cell performance resulting from hydrogen fuel containing CO. Here, we had several investigations into CO poisoning on dependence of types of catalyst between Pt and Pt-Ru alloy. The results are summarized as follows: 1) The poisoning prediction formulas and the poisoning estimation coefficient to predict and estimate the FC performance were derived theoretically. 2) The actual process of CO poisoning was scrutinized by focusing on adsorption of CO and desorption of CO2 molecules, and changing of several polarizations of FC caused by CO poisoning were estimated. 3) Investigations into the relationship between the CO concentration, operating pressure, operating temperature and the CO poisoning were carried out. If FC underwent at a high CO concentration, no significant improvement could be expected by operating at increased pressure, and effects of the operating temperature is almost the same between two types of catalyst.
