“…However, the flow fields suitable for PEMFCs are not compatible with AEMFCs due to their different water transport characteristics. A threedimensional multi-phase model was implemented by Cheng et al [175,176] to investigate the feasibility of metal foam (MF) flow fields in AEMFCs and the effects of the design and operating parameters. Their findings suggest that AEMFCs with MF flow fields have more uniform substance distribution (e. g., liquid water, water vapor, and oxygen) and uniform temperature distribution compared to AEMFCs with conventional serpentine flow channels, as shown in Figures 15(i) and (j).…”

Anion exchange membrane fuel cells (AEMFCs) are the most promising low‐temperature fuel cells and have received extensive attention. Compared to PEMFCs, the cost per unit of power can be significantly reduced for AEMFCs because, in theory, they allow the usage of non‐precious metal catalysts and low‐cost cell components. Owing to the development of advanced materials and performance improvement strategies, AEMFCs have achieved new records in both initial performance and durability. However, the high performance currently achieved is contingent on certain conditions, e. g., high Pt loading, large gas flowrates, and operation in pure O2, which are far from practical applications. Therefore, the transition to commercially relevant performance and durability is the next goal of AEMFCs. This paper reviews the performance data of H2‐fueled AEMFCs since 2010 and summarizes possible performance optimization schemes, which can provide useful insights for developing next‐generation AEMFCs.
