Army produces tractor-trailer with fuel cell

| 3/6/2003

The U.S. Army has unveiled a new tractor-trailer that uses a fuel cell for many of its electrical needs, eliminating the need for idling, Reuters news service reported March 4.

The fuel cell, which is powered by methanol, could save some trucks upward of 2,000 gallons of fuel a year.

The army uses a 5-kilowatt fuel cell, which produces enough power for about five average homes. However, the cost of the system, Reuters reported, is much higher than traditional alternatives. A diesel generator runs $800 to $1,500 per kilowatt, rather than the fuel cell’s $4,500 per kilowatt.
