Abstract
Performance degradation of polymer electrolyte fuel cells (PEFCs) is caused by water flooding and plugging on cathode side. In this paper, the liquid water behavior in the cathode channel of a PEFC was observed directly by using cross-sectional visualization technique. Furthermore, the effect of hydrophilic treatment of the channel wall on the through-plane liquid water transport and performance characteristics was discussed considering operating conditions.
