Recent Advances on PEM Fuel Cells: From Key Materials to Membrane Electrode Assembly

Abstract In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide attention from academia, industries, investors, and governments. The prospect of PEM fuel cells has turned into reality, with fuel cell vehicles successfully launched in the market. However, today’s fuel cells remain less competitive than combustion engines and batteries, primarily due to their high cost and short lifetime, which are significantly affected by the membrane electrode assembly (MEA), or the “chips” of PEM fuel cells. Therefore, many efforts have been devoted to developing advanced materials and manufacturing processes for MEAs. In this paper, we critically review the recent progress of key materials for…
