are as follows : 1) Various experiments and analyses were conducted to determine the adverse effects of CO, HCHO, HCOOH, and CH_4 on the performance of the FC ; 2) In the case of HCHO and HCOOH poisoning, performance became worse when Ru was added to the FC catalytic-electrode ; 3) The quantities of the partial pressure decline phenomenon of hydrogen gas caused by mixing CO_2 and N_2 gases appeared to be the same ; 4) The progress of poisoning with the reforming gas was complex ; however, explanation became possible by taking CO poisoning and the influence of the partial pressure decline phenomenon of hydrogen gas into consideration.

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 CO_2 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.
