Research supported by the Department of Energy's Hydrogen Program has yielded substantial progress in hydrogen production, delivery, storage, and fuel cell technologies. The Program has met its hydrogen cost target of $3/gas gallon equivalent (gge) for hydrogen produced by distributed natural gas reforming, down from $5/gge in 2005. While some current fuel cell vehicles have a range exceeding 300 miles, the Program have identified promising materials-based technologies to achieve this range across all vehicle platforms without compromising passenger or cargo space, performance, or cost. In the area of fuel cells, the projected cost for a mass-produced, polymer electrolyte membrane (PEM), automotive fuel cell system has been reduced to $73/kW from $275/kW in 2002. Program-funded research has led to improvements in conductivity for high-temperature PEM fuel cell membranes at low relative humidity, and to the development of a membrane electrode assembly (MEA) with over 7,300-hour durability. |
