A robust electrical power-source is being developed based on a high-temperature (T = 140 to 230°C) polymer electrolyte membrane fuel cell (HT-PEMFC) that is fed air and hydrogen rich fuel from a hydrocarbon reformer. The chemical to electrical conversion efficiency, η, is projected to be 25 to 40% in a system with a relatively high specific power density of about 0.1 kWatt/kilogram and energy density of about 1000 Watt-hour/kilogram. These projections are based on advances in fuel cell and reformer materials as well as results with a 10-Watt breadboard, which had a HT-PEMFC and methanol steam reformer.
