Zinc/air fuel cell, where the stable metal zinc in pellet or particle form is used as fuel rather than hydrogen. In the electrochemical reaction of zinc with oxygen, zinc oxide is formed. This zinc oxide can be recycled to make new zinc fuel. Electrolytes in a ZAFC can be liquid, such as seen in the Metallic Power fuel cell, www.MetallicPower.com or in solid form, such as seen in the Electric Fuel Corp. and EVionyx ZAFCs (FCIR online July 2001), www.electric-fuel.com, www.evonyx.com. The Norwegian company, ReVolt Technology AS, has developed a rechargeable zinc/air battery that it claims has higher power density than Li-ion batteries, www.powerpulse.net/news/story.php?id=13482.
