Solid polymer fuel cells for transport and stationary applications

Progress is reported toward the commercialization of solid polymer fuel cell (SPFC) (also known as the proton-exchange membrane or PEM fuel cell) technology. A full size transit bus powered entirely by an SPFC, sufficiently compact to fit within the standard bus engine compartment, is described. The first order for a test fleet of these buses is also reported. Progress in the development of fuel cell stacks for stationary and motive applications is described. A high power density SPFC stack producing over 1000 W/1 is reported.
