质子交换膜燃料电池的研究进展

Advances in Proton Exchange Membrane Fuel Cell

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,分隔氧化剂与还原剂的作用.PEMFC用电催化剂有铂系和非铂系电催化剂,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.文中对电极的制备技术和电池的水管理、热管理方法也作了简要介绍.

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,whose working is transferring protons and 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 to be the main trends in the future research.Electrode preparation technique, water and heat management of fuel cells is also discussed.
