Proton exchange membrane fuel cells have been known to promising energy devices. However, high cost and low durability of their electrocatalysts hinder the widespread commercialization. Anion exchange membrane Fuel cells have the potential as an alternative to PEMFCs. Under alkaline conditions, the kinetics of the oxygen reduction reaction are enhanced compared to acidic environment, leading to improve fuel cell efficiency. Also, the facile kinetics of ORR allows the use of nonprecious metals as a catalysts, resulting in reducing the cost of the fuel cell. Recent studies have focused on development of AEM, ionomer and electrode design. However, there is a lack of research on operating condition, water management, and membrane-electrode-assembly for realizing the maximum performance of AEMFCs. In this study, to maximize the performance of AEMFCs, we investigate the key factors that influence the performance of AEMFCs, especially focused on controlling the material used in fuel cell. |
