DoCoMo plans fuel-cell mobile phones

By at 12:41 pm Friday, Aug 8

Mobile phones made with platinum that use fuel cells instead of batteries are expected to become available in 2004, according to an announcement by Japan's DoCoMo:
Fuel cells require platinum as a major component to enable them to generate energy. Platinum increases electrical conductivity in PEM (proton exchange membrane) fuel cells. It is critical to fuel cell commercialization and can alone command 10% to 20% of a fuel cell system's cost. Accepting the U.S. Department of Energy's target for platinum use in fuel cell vehicles - 0.2 grams per kilowatt - total platinum use by fuel cell systems could bring an 8% to 12% increase to the world demand for platinum by 2013, according to ABI projections.
