Anion-exchange membrane fuel cells (AEMFCs) potentially allow the use of cheap catalysts due to their alkaline environment, yet often large amounts of precious metals are employed. Now, a non-precious metal-based catalyst, specifically designed for alkaline media, is demonstrated in the cathode of a high-performing AEMFC.

解决一个基本问题

阴离子交换膜燃料电池 (AEMFC) 由于其碱性环境而可能允许使用廉价催化剂，但通常使用大量贵金属。现在，一种专为碱性介质设计的非贵金属基催化剂在高性能 AEMFC 的阴极中得到展示。
