摘要：

An experimental apparatus for a PEFC was constructed with which the local ionic resistance distribution can be measured as well as the local reaction current distribution, using segmented current collectors and an AC resistance meter. The apparatus presented a clear view on the current distribution and its causes: hydration and dehydration of the membrane and the oxygen consumption along the gas streams. The effects of flow direction, gas stoichiometry and humidification were examined.
