  • 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: 7976970
    Abstract: Method and apparatus for establishing a fuel cell unit (10) in the form of an extruded monolith having channels (14), of which every second constitutes a fuel channel (14a) and every other second an oxygen channel (14b). The channels (14) are designed in such a manner that the fuel channels (14a) are displaced laterally in relation to the oxygen channels (14b), in such a way that all the fuel channels (14a) protrude a certain distance from the end points of all the oxygen channels 14b) and all the oxygen channels (14b) protrude a certain distance from the end points of all the fuel channels (14a). The distance is less than the length of respective channels. The invention also relates to a fuel cell device that includes several of the fuel cell units (10) that together establish an enhanced system of fuel cell units that lend themselves to compact.
