Exchange Membrane

In order to improve the power output of a fuel cell, a novel approach for gas delivery and mass transfer enhancement in a gas distributor is proposed. A model analyzing the power output against the dimensions of a novel gas delivery channel and current collector is also presented. Experimental study for some proton-exchange-membrane fuel cells and numerical analysis for a planar type solid oxide fuel cell are carried out. Significant improvement of power output was obtained for the newly designed fuel cells compared to conventional ones. Both the experimental results and modeling analysis are of great significance to the design of fuel cells.
