摘要： In a fuel evaporator provided with an evaporation chamber 11 that produces raw fuel gas FG by vaporizing raw fuel liquid by heat received from a plurality of heat medium tubes 12 through which a high temperature heat medium passes, a raw fuel injection portion that injects raw fuel liquid onto the heat medium tubes 12 is situated in the evaporation chamber 11. The heat medium tubes 12 are arranged sparsely near the raw fuel injection portion and densely away from it. A catalytic combustor 20 is provided adjacent to the bottom surface 11b of the evaporation chamber 11 to form the high temperature heat medium. Such a fuel evaporator efficiently vaporizes raw fuel liquid and can be suitably applied in a fuel cell system for a fuel cell-powered automobile.

The improved system employs a novel arrangement of components which provides improved interaction between the subsystems while also simplifying the apparatus by integrating components to provide improved thermal and electrical efficiency. The fuel processing subsystem preferably comprises a furnace for providing heat to a plurality of components disposed within the furnace. In one embodiment, a reformer, a fuel stream humidifier, and a heat exchanger are all disposed within the furnace vessel, with the outlet of the humidifier fluidly connected to the inlet of the reformer and the outlet of the heat exchanger fluidly connected to a desulfurizer located external to the furnace. The fuel processing subsystem may further comprise a shift reactor that exchanges heat with a cathode exhaust stream directed to the shift reactor from the power generation subsystem. After passing through the shift reactor, the cathode exhaust stream is preferably directed to the furnace burner.

摘要： The fuel cell apparatus has a fuel-producing unit (2) for producing hydrogen-enriched fuel (6) and a fuel cell or fuel cell stack (1) for production of electrical energy from the hydrogen-enriched fuel and air. It also includes at least one compressor (5,7; 17) for providing the fuel cell or fuel cell stack with an over-pressure, in order to decisively reduce the danger due to leakage and to guarantee reduced energy consumption and reduced costs for supply of the apparatus. Since at least one operating pressure is less than atmospheric air pressure, the apparatus provides these advantages. The apparatus also preferably includes at least one burner unit (9) for consuming excess hydrogen-containing fluid. In a preferred embodiment one compressor unit is arranged between an outlet of the fuel cell or fuel cell stack and an outlet of the apparatus for exhaust gas in order to provide a low pressure to draw in hydrogen-enriched fuel. Another separate compressor unit is optionally arranged upstream of an entrance to the fuel cell for a second oxygen-containing fluid stream.
