Abstract

The fuel cell battery (1) for liquid fuels has the following components: a cell stack (2) which is arranged along an axis (2a) and within a periphery (2b); a distributor passage (21) on the stack axis (2a) via which a reformed fuel gas can be fed in into cells (20) of the stack (2); afterburner chambers (22) at the stack periphery (2b); furthermore an auxiliary burner (3) for a start-up operation. A reaction device (3) is in connection with the cell stack and is provided for the treatment of the liquid fuel by reforming with partial oxidation to form a fuel gas which contains CO and H.sub.2. A heat exchanger system (4) is integrated into the reaction device, by means of which, in a current delivering operation of the battery (1)--using hot exhaust gas from the afterburning chambers--the liquid fuel can be vaporized and a gaseous oxygen carrier can be heated up. Via an infeed point (6) which is part of the heat exchanger system, vaporized fuel can be brought into contact with a heated up oxygen carrier for forming the reformed fuel gas. This fuel gas can be fed in from the reaction device into the distributor passage of the cell stack.
