The CCM-type MEA is the core component of PEMFC, first coat both sides of proton exchange membrane (PEM) with a catalyst layer (CL), and then press the anode/cathode gas diffusion layer (GDL) on two sides of ion exchange membrane to manufacture membrane electrode assembly. Therefore, …

GDE-type MEA, also known as gas diffusion electrode, it’s a core component in PEMFC structure which converts chemical energy into electrical energy. The electrode has porous structure to fully connect the catalyst, reaction gas & liquid in three-phase region, remove remove water and reactants generated …
