Abstract:

Membrane electrode is a key component of proton exchange membrane fuel cell (PEMFC). This paper reviews recent advances in membrane material, electrode catalyst and gas diffusion layer based on its structure, including Nafion modified membrane, SPA / SPE (sulfonated poly aromatic hydrocarbons) class film, Pt modified catalyst, nonnoblemetal catalyst and GDL diffusion layer. The paper then points out that we should focus the simple improved method of Nafion membrane, development of aromatic hydrocarbon polymer blend membrane, research on Co and N contained electrode catalyst and the development of microporous layer, externally rough and strongly hydrophobic gas diffusion layer in future.

Key words: proton exchange membrane fuel cell, membrane electrode, sulfonated aromatic polymer, gas diffusion layer
