Proton Exchange Membrane Fuel Cells (PEMFC) are seen by many as a future replacement for internal combustion engines but problems associated with sub-freezing temperature startup must first be resolved for widespread acceptance.

PEMFC's convert hydrogen and oxygen into electricity, but during the conversion process, water is needed and produced but can freeze , damaging the fuel cell and delaying rapid startup of the vehicle.

With support from DOE's Hydrogen Program, the National Renewable Energy Laboratory recently released a report, "PEM Fuel Cell Freeze and Rapid Startup Investigation," which identifies issues for rapid startup of PEMFC's in sub-freezing temperatures and investigates proposed solutions and strategies.
