Water Management for of Proton Exchange Membrane Fuel Cells Marketing and Sensitive Balance

Abstract

Electromembrane processes are a significant component of electrochemical technology. Now it is well accepted that the performance and durability of proton exchange membrane fuel cells (PEMFCs) are inextricably linked to the buildup and transit of water inside their porous components, notably the gas diffusion layer (GDL) and microporous layer. In this paper, the electroosmotic drag in membranes and water management which is the chief difficulty facing the membrane are discussed and a review of the mechanism of transport and membrane water transport with sorption/desorption are presented.
