A high-performance Al-air fuel cell using a mesh-encapsulated anode via Al–Zn energy transfer

Summary: Aluminum-air fuel cells attract more attention because of their high specific energy, low cost, and friendly environment. However, the problems of hydrogen evolution corrosion and low anode efficiency of aluminum-air fuel cells remain unresolved. Herein, we propose an aluminum-air fuel cell...
