【摘要】 质子交换膜燃料电池(PEMFC)是一种高效节能、工作稳定、环境友好的理想发电装置。质子交换膜是PEMFC的核心组成,是一种选择透过性膜,主要起传导质子、分割氧化剂与还原剂的作用。PEMFC用电催化剂主要为铂系电催化剂,为降低成本,提高铂的利用率和开发非铂系催化剂是今后催化剂研究的主要方向之一。对PEMFC电极的工作原理,关键组件及电池的水管理、热管理方法等作了综述。更多还原

【Abstract】 The proton exchange membrane fuel Cell(PEMFC) is an ideal generator,which is efficient,stable working and friendly with environment. The proton exchange membrane,a selective passable membrane,its working is transferring protons,parting oxidant and deoxidant,is the core of the cell. The electrocatalyst for proton exchange membrane fuel cells includes the platinum and the substitution of platinum electrocatalyst. Therefore,Improving the utilization of platinum and exploiting the substitution of platinum are expected. The working principle and the key components of PEMFC electrode were briefly introduced. The water and heat management of fuel cells were also discussed.更多还原
