Analysis of accelerated degradation of a HT-PEM fuel cell caused by cell reversal in fuel starvation condition

This paper reports an accelerated degradation test of a high temperature PEM fuel cell under repeated H2 starvation condition. The H2 stoichiometry is cycled between 3.0 and 0.8 every 2 min during the test. The experimental results show that the polarity of the fuel cell is reversed under H2 starvat...
