Polymer Ion Conducting Membranes are the most important parts in fuel cells. Generally

polymer electrolyte membrane fuel cells include proton exchange membrane fuel cell (PEMFC) and alkaline polymer membrane fuel cells (APEFC )

according to the counter ions of polymers. In this article

we focus on the advance of PEM under high temperature and low humidity condition in fuel cell (HTPEM)

and the alkaline polymer membranes (APE ) recently. Then the key issues and the prospects of HTPEM and APE are illustrated in fuel cells

and the research work in HTPEM and APE in our lab is introduced accordingly.
