www.nrel.govprimarily proton exchange membrane (PEM) fuel cells. PEM fuel cells are the preferred fuel cell technology for vehicles and other new applications because of their fast start-up time and low operating temperature. These fuel cells are used for stationary power, primarily in backup power units, and to produce electricity for electric vehicles.
