Among the various types of fuel cells, proton exchange membrane fuel cell (PEMFC) has shown great interest in its use in stationary and transport applications due to its low operating temperature, solid state electrolyte and its relative compactness. However, before mass marketing, the current PEMFC technology still has issues of limited lifespan and reliability (aging) due to its many components: the bipolar plate, diffusion layer, catalyst layer, electrolyte, etc.
