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.
