Patent number: 8641789Abstract: 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.Type: GrantFiled: July 13, 2007Date of Patent: February 4, 2014Assignee: Powercell Sweden ABInventors: Bård Lindström, Lars Pettersson, Staffan Lundgren
