Tsinghua team develops zinc-air fuel cell stack with high power density

Green Car Congress

Researchers at Tsinghua University have developed a high-power-density zinc-air fuel cell (ZAFC) stack using an inexpensive manganese dioxide (MnO 2 ) catalyst with potassium hydroxide (KOH) electrolyte. Moreover, zinc has other merits, such as, abundant resources, low cost, low toxicity, easy storage and safe handling.
