Abstract

A heat exchange cell and to a method of utilizing the waste heat of an air-cooled fuel cell battery is described. The heat exchange cell is of a configuration similar to that of the fuel cell and, in the stack, should directly adjoin the fuel cell battery, so that the spent cooling air is utilized to heat a medium without an intermediate line.
