ABSTRACT:
A high-temperature fuel cell includes two chambers to be acted upon by a reaction gas. A partition is formed of an oxygen-conducting ceramic material with a given coefficient of thermal expansion. The partition separates the chambers from one another and defines outer walls of the chambers opposite the partition and side walls of the chambers contacting the partition. Electrodes are each disposed at a respective side of the partition. The outer walls are formed of a soft metal sheet having at least one corrugation for compensation of expansion and the side walls are formed of a material with the given coefficient of thermal expansion. A high-temperature fuel cell stack may include a plurality of series-connected high-temperature fuel cells.
