[ 1 ] - Effect of Sealing Gas Washer Design on a PEM Stack Fuel Cell Performance
In this paper we study the performance of a PEM stack fuel cell after 900 hours of operation. We tried to identify any voltage degradation and its causes. Microscopic cracks on some parts of MEA mainly due to uniformity of pressure, stress concentration and elongation of membrane in the edge of GDL has been identified as the most important cause of this gradual degradation. High contact resista...
