摘要: The importance of flow field design in a Polymer Electrolyte Fuel Cell (PEFC) cannot be overemphasized. Experimental evidence suggests the presence significant amount liquid water PEFC gas channels and typical driving cycle city that vehicular engine is unlikely to reach steady state operation under these conditions. Therefore need for an unsteady two-phase model critical. “Multiphase Mixture” (M2) used develop efficient cathode channels. Liquid evolution its effect on pressure drop history investigated with help model. It tool evaluate performance new designs as well test loss due channel blockage. same could extended anode channels.Copyright © 2011 by ASME
