Research of Non-Platinum gas diffusion electrode preparation for anion exchange membrane fuel cells
One of the most merits of AEMFCs compared to PEMFCs is the ORR at cathode is much faster, resulting in that non-noble metals can be used as cathode catalysts. However, based on the principle of AEMFCs, it is expected that water management in AEMFCs is more complicated than that in PEMFCs. On the oth...
