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

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

Many efforts are focused on batteries and fuel cells, which can be used for EVs propulsion and large-scale energy storage. However, the existing batteries and hydrogen fuel cells cannot meet all the market needs; for example: low price, high safety, longer lifetime, and zero pollution. For electrochemical power sources, it is worth noting that zinc possesses a unique set of characteristics as anode material, including low equilibrium potential, electrochemical reversibility, stability in aqueous electrolytes, good conductivity, low equivalent weight, high specific energy, and high volumetric density. Moreover, zinc has other merits, such as, abundant resources, low cost, low toxicity, easy storage and safe handling.
