  • Patent number: 8999016
    Abstract: A fuel processor for generating hydrogen rich gas or cleaned hydrogen rich gas from hydrocarbon fuel includes an inner housing and an outer housing defining a mantel space between them, wherein at least one fuel reformer unit for reforming hydrocarbon fuel to a hydrogen rich gas and optionally a gas-cleaning unit for cleaning the hydrogen rich gas from unwanted by-products are arranged in the inner housing. The fuel processor further includes a processor inlet for introducing hydrocarbon fuel into the inner housing and a processor outlet for releasing cleaned hydrogen rich gas from the inner housing. The outer housing further includes a fluid inlet for introducing a heat transporting fluid into the mantel space. The inner housing includes at least one opening for providing a fluid-connection between the inner housing and the mantel space. A method for operating such a fuel processor is also provided.

  • Patent number: 8936883
    Abstract: An arrangement and a method are provided for generating hydrogen from hydrocarbon fuel, wherein hydrocarbon fuel is supplied to a fuel reformer for producing hydrogen rich gas including hydrogen, carbon monoxide and possibly unconverted fuel compounds, wherein the amount of carbon monoxide and/or the unconverted fuel compounds is reduced with the help of a molten salt reactor arranged downstream the fuel reformer. An auxiliary power unit including such an arrangement is also provided.

  • Patent number: 8641789
    Abstract: A reformer reactor is provided for converting hydrocarbon fuel into hydrogen rich gas by auto-thermal reaction process. The reformer reactor has a preferably cylindrically shaped, double wall housing with an inner wall and an outer wall and two side faces, wherein the inner wall and the two side faces form a reaction chamber. Additionally, the inner wall is charged with a first electric charge which prevents the hydrocarbon fuel molecules injected into the reaction chamber by a fuel inlet from hitting the warm inside surfaces of the reaction chamber and burn to soot, subsequently.

  • Patent number: 7790330
    Abstract: A polymer electrolyte fuel cell structure includes a proton exchange membrane (4). An anode catalyst layer (1,16) is located on one side of the proton exchange membrane. A cathode catalyst layer (7) is located on the opposite side of the proton exchange membrane, and a gas distribution layer (3,5) is arranged on each side of the proton exchange membrane (4). The anode side gas distribution layer (3) is a flat, porous structure having water channels (3a) formed in the surface facing the membrane (4). The anode side gas distribution layer (3) is enclosed by a coplanar, sealing plate (2) with water inlet channels coupled to the water channels (3a) in the gas distribution layer.
