This project conducted at ENSIC in Nancy, France studied the operation of a PEMFC at low voltages and tests were done to determine if current control with hydrogen flow was possible and the degradation effects on the MEA. Varying length CA and CP tests were conducted. Performance and degradation of the fuel cell were analyzed using GEIS, LSV, and CV. It was determined that the current of a FC could be directly controlled by hydrogen flow within 3% of the target value. Operating at a low voltage of 0.2 V presents a potential application of FCs with supercapacitors and minimal degradation effects. Additionally running a FC with dry inlet gases or at OCV for an extended time was found to rapidly “kill” the MEA.
