Proton exchange membrane fuel cells operated in the dead-ended anode mode can improve the utilization of hydrogen and simplify the fuel cell system. Gas purging was an effective way to remove the excess water to avoid water flooding and performance degradation in PEMFC. Effective back diffusion of w...
