Abstract:Fossil energy is being exhausted， the problem of environmental pollution needs to be solved urgently， and the social demand for energy is increasing day by day. Proton exchange membrane fuel cell has been widely concerned by researchers because of its advantages of high efficiency and good environmental protection. The gas-liquid transport performance of the gas diffusion layer in proton exchange membrane fuel cells is an important factor affecting the output performance， working stability and service life of the fuel cells. This paper reviewed the recent studies on the gas diffusion layer， microporous layer， and theoretical modeling， to provide reference and ideas for improving the performance of fuel cells and solving water management problems in the future.
