This major qualifying project conducted at ENSIC in Nancy, France, seeks to investigate these effects by studying the degradation of a PEMFC operating at low voltage. This experiment achieved low voltage operation by short-circuiting the fuel cell using a copper bracket. The cell operated for a total of six weeks where weekly characterization tests were conducted to evaluate the health of the membrane. The degradation of the fuel cell MEA was characterized by polarization curves, impedance spectroscopy, linear sweep voltammetry, and cyclic voltammetry. Research determined that over the course of the experiment the performance of the fuel cell decreased. However, voltammetry testing indicated that the membrane and catalyst layer degraded little over the course of six weeks.
