Abstract

A Proton Exchange Membrane Fuel Cell (PEMFC) is developed as a potential solution in power supply applications. Performance of PEMFC was depicted by current density and voltage. The water liquid content in PEMFC depend on several factors. Current density is one of factors that affect water liquid formation in PEMFC. This study aimed to know the influence of current density of water liquid formation in Cathode. The result was shown that at temperature from 303 K to 333 K, the water liquid formation was small at higher current density. At current density above 1Acm-2, it makes little difference of water liquid content. Increasing the temperature (about 343 K) will decrease the performance of PEMFC, which is Relative Humidity Cathode (RHC) 50% and the Relative Humidity Anode (RHA) 90 %..
