  • 7. 7Challenge the futureZero EZEPEM Fuel Cell SafetyElectrolyte: a polymer electrolyte in the form of a thin, permeablesheet.Efficiency: is about 40 to 50%Operating temperature: about 80 degrees C (about 175 degrees F).Cell outputs: range from 50 to 250 kW.The solid, flexible electrolyte will not leak or crack, and these cellsoperate at a low enough temperature to make them suitable for homesand cars. But their fuels must be purified, and a platinum catalyst is usedon both sides of the membrane, raising costs
