Abstract: An electric generator for a motor vehicle, including: a reformer for producing a reformate from a primary fuel, water and air; circuits supplying the reformer with primary fuel, air, and water; a fuel cell for production electric power from the reformate and air; a compressor for compressing the air for the fuel cell and/or the reformer; and circuits for supplying the fuel cell with reformate and air, connecting the fuel cell to the reformer and the compressor, respectively. The circuits supplying water to the reformer include a first heat exchanger for establishing heat exchange relationship between the water and the air compressed by the compressor.

Abstract: The invention concerns an electric generator for a motor vehicle, comprising: a reformer (60) for producing a reformate from a primary fuel, water and air; circuits supplying the reformer with primary fuel (64), air (36, 40, 38, 62) and water (82, 86, 90, 66), a fuel cell (20) for production electric power from the reformate and air, a compressor (36, 38) for compressing the air for the fuel cell (20) and/or the reformer (60), circuits for supplying the fuel cell with reformate (80, 82, 84, 86, 88, 90, 92, 94, 22) and air (24), connecting the fuel cell to the reformer and the compressor (36, 38), respectively. The inventive generator is characterized in that the circuits (82, 86, 90, 66) supplying water to the reformer comprises a first heat exchanger (130; 40; 50) for establishing heat exchange relationship between said water and the air compressed by said compressor (35; 38).
