燃料电池质子交换膜研究进展与展望

Progress and Prospect of Proton Exchange Membrane Research

质子交换膜燃料电池(PEMFC)作为一种清洁高效的能量转换装置,具有比功率高、稳定性好、易于启动等优点,是未来可移动动力源的理想候选。成本和寿命是阻碍PEMFC商业化的主要原因,寻找新型材料是解决这两大问题的必然选择,也是近年来质子交换膜研究的热点和重点。本文介绍了几种质子交换膜材料的研究进展,主要包括聚合物型、陶瓷型和有机-无机复合型,讨论了各种膜材料的特点,并对其未来的发展加以展望。

Fuel cell is a kind of clean and high-efficiency energy conversion device. Proton exchange membrane fuel cell （PEMFC）, with the advantages of high specific power, high stability and rapid operation, is an ideal candidate for the portable power sources in the future. Cost and lifetime are the biggest obstacles in the way of PEMFC^s commercialization, which must be solved by searching and developing novel materials. These areas also become the keystones and hotspots in proton exchange membrane research and development. This article introduces the latest research progress of proton exchange membrane materials, mainly including： polymer, ceramic and organic-inorganic compounds. At the same time we discuss the feature of each material and the prospect of proton exchange membrane in the future.
