Abstract

The invention relates to a system having high-temperature fuel cells, for example SOFCs. A reformer connected upstream of the high-temperature fuel cells at the anode side, a start burner for the preheating of the cathodes of the high-temperature fuel cells, an afterburner and an operating heat exchanger are present at the system in accordance with the invention. Oxidizing agent can be supplied to the high-temperature fuel cell cathodes through the operating heat exchanger. In addition, it can be heated with the exhaust gas of the high-temperature fuel cells. Exhaust gas conducted through the operating heat exchanger can flow in an exhaust gas line together with environmental air and can then be conducted away into the environment as cooled exhaust gas.
