高温质子交换膜燃料电池解决了传统质子交换膜燃料电池催化剂易受CO等杂质气体毒化、水热管理复杂等问题,成为当今燃料电池发展的主要方向。高温质子交换膜是实现高温操作的关键部分。本文结合质子传递机理,分析了以水作为质子溶剂、非水质子溶剂质子交换膜以及无机固态质子导体膜的研究现状,认为有机/无机复合膜和非水质子溶剂膜,尤其是其中的磷酸掺杂的PBI膜是高温质子交换膜的发展方向。

High temperature proton exchange membrane fuel cell(PEMFC) is a solution to the most important issues which exist in the operation of traditional PEMFC,including CO poisoning and complexity in water and heat management,thus becomes the main focus in fuel cell development.High temperature proton exchange membrane(HT-PEM)is the key component for high temperature operation.The present state-of-art of HT-PEMs is analyzed,including polymers with water as proton solvents,anhydrous membranes and solid-state protonic conductors,with the consideration of the proton conducting mechanism in the membranes.Inorganic/organic composite membranes and anhydrous membranes(especially phosphoric acid doped polybenzimidazole(PBI) membranes) are regarded as the future focus of HT-PEMs development.
