Fuel Cells

Fuel Cells are batteries powered by a chemical reaction.
Zolair Energy, an enterprise based in Vancouver, leases rechargeable zinc-air fuel cells to households and villages in Southern Africa, where customers pay for electricity on demand. Zinc-air fuel cells use the chemical reaction of the metal zinc with the oxygen in the air to generate electricity, which can be used to power a multitude of different devices and appliances. Fuel cells are brought to a small-scale distributor to recharge.
