Progress in the R & D of self-humidifying and air-breathing proton exchange membrane fuel cell
摘要
Abstract
Air-breathing proton exchange membrane fuel cell (AB-PEMFC) is able to actively absorbing air,and widely applied in various mobile power system due to its high energy transition efficiency and the product’s environmental friendship. However,before the commercialization of AB-PEMFC,it must solve the problems such as fuel leakage,water produced by reactions,heat dissipation,stability of long-time running and the dry-out of the membrane or catalyst layer caused by reactant gas without sufficient external humidification and the electro-osmotic drag,diffusion and evaporation of inner water molecules. Thus this paper introduces research progress on key components of AB-PEMFC,for example,design of novel hole patterns for transporting water and oxygen on cathode current collector of single cell and selection of materials for gas diffusion layer and bipolar plate. It also presents methods of adding hydrophilic materials into catalyst layer or modifying the substrate of catalyst to fabricate self-humidifying membrane electrode assembly (MEA). By introducing a few application examples,we present the progress trends and applications of AB-PEMFC. Furthermore,some methods to improve the performance of AB-PEMFC have also been summarized.关键词
