More Information
Summary:A fuel cell stack includes a plurality of solid oxide fuel cell tubes and a heat recuperator. The heat recuperator is formed from sheet metal. The plurality of walls define an exhaust gas channel having an exhaust gas flowing therethrough and an oxidant channel having an oxidant flowing therethrough. The exhaust gas channel is in thermal communication with the oxidant channel such that heat is transferred between the exhaust gas and the oxidant.
