摘要：

Polymer electrolyte fuel cells (PEFC) in the regime of limiting current is considered. Maximum current limitations come due to oxygen deplete on the cathode. They appear strongly dependent on the geometry of the gas diffuser and supply channels. Effect of liquid water in the electrode and air pressure in gas channels is studied to identify the best geometry of the gas supply net in the terms of the maximum cell Current. Comparison between model predictions and experimental data is carried out. (C) 2003 Elsevier B.V. All rights reserved.
