Leo Motors, Inc. displayed two electric trucks equipped with a new Zinc Air Fuel Cell (ZAFC) system as a range-extender at the EV Korea 2010 Expo. 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 has developed a fuel distribution system for the even distribution of the zinc pellets into the stack. 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.
The performance of the ZAFC generator was tested by the Korea Electric Technology Institute, run by the Korea government, Leo said.
The trucks on display were converted from traditional internal combustion engines to EVs. The e-Porter is a one ton, (2,200 lb load) truck, while the e-Labo is a half ton pick-up truck. Leo also exhibited an electric passenger car, motorcycle, utility EV, and five e-scooters at the event.
