Abstract
A fuel cell battery is operated with an afterburning at the periphery of a cell stack. Each cell of the battery has at least one entry point for air or another gas containing oxygen. The afterburning is provided inside a ring-shaped space about the cell stack. The named entry points are communicatingly connected as a totality or in each case group-wise via at least one air space, which extends axially along the cell stack and which stands in direct contact with the latter. Each air space is separated from an afterburner chamber, which likewise forms a space which communicates axially along the cell stack, by at least one wall.
