Summary:

In order to assess the effect of PEM-FC poisoning resulting from impurities on PEM-FC performance, this paper investigated contents as follows; · Estimation for composition and concentration of impurities contained within hydrogen fuel and air. · The prediction of poisoning extent and proposal of assessment index for impurity poisoning. · Allowable mixing concentration of impurities for the standard H2 fuel. The analysis and experiment are conducted under 70 °C and 1 bar for operating temperature and pressure. PEM-FC with Pt and Pt-Ru type catalytic-electrode was used. It was observed that: · CO poisoning was reversible but H2S and SO2 poisonings were irreversible. It was also confirmed that sulfur compounds poisoning was very strong. On the contrary, poisoning of HCHO and CH4 et cetera was slight or negligible. · In case of cathode electrode, the effect of NO2 and SO2 poisoning on PEM-FC performance was severe when CO poisoning was negligible
