Fuel cells are considered a promising future technology for energy conversion, and the key factor in fuel cell performance is the structure of the electrode in the membrane electrode assembly (MEA). Hence, optimization and modification of electrocatalysts and electrode structure have proven to be critical for improving the performance and durability of fuel cells. Accordingly, in this study, we will consider several attempts such as ordered macroporous platinum electrode for enhancement mass transfer and improve water management, core-shell structure electrocatalysts for durability, and replacing the expensive Pt-group metal (PGM)-based catalysts used in the oxygen reduction reaction (ORR) with inexpensive, more abundant nonprecious materials. Also, basic operation condition and MEA optimization of alkaline anion exchange membrane fuel cells (AEMFCs) are discussed as well. |
