This paper covers our investigation into a decline in productivity resulting from hydrogen fuel containing impurities in methanol reforming type fuel cells. Here, we had several investigations into poisoning using reforming gas adopting STR and ATR method. The results are summarized as follows : 1) The influence of CO_2 and N_2 mixed into fuel was examined. It could confirm that the poisoning didn't occur with these gases, therefore, the quantities of partial pressure decline phenomenon of hydrogen gas caused by mixing these gases are thought to be the same. 2) Experiments were carried out by using the gas formed from reformer. The progress of poisoning of this case is complex, however explanation of this phenomenon became possible by taking CO poisoning and the influence of partial pressure decline phenomenon of hydrogen gas into consideration.
