Composites Fuel Growth of Fuel Cell Technology

The predominant fuel cell type for transportation applications is the proton exchange (or polymer electrolyte) membrane fuel cell (PEMFC), which uses pure gaseous hydrogen stored onboard in pressurized tanks. At the heart of a PEMFC is the "stack," the core element that generates electrical energy to power the vehicle. Unlike internal-combustion and hybrid power plants, the only emissions from the fuel cell's noncombustible reaction are a small amount of water and heat in the range of 175-400°F. Although fuel cell stacks can be, and are, built with metals, designing key stack components with composites has contributed to system weight and parts-count reductions. At the same time though, composites have increased mechanical strength and corrosion resistance, provided for tailorable conductivity, and given fuel-cell manufacturers the ability to easily mold complex geometries into PEMFC components.
