Leo Motors Exhibits Electric Trucks with Zinc Air Fuel Cell Range Extenders

Green Car Congress

Leo filed for patents on the ZAFC technology in 2008. The refuelable ZAFC oxidizes zinc pellets, generating the power to recharge the Li-ion polymer battery pack. Leo also developed a mechanism to halt power generation when the battery is fully charged, and for collection of the zinc oxide sludge from the stack.
