Abstract (en)

[origin: WO2007082522A1] The invention relates to a method and a system for operating a high-temperature fuel cell. The system comprises at least one fuel cell, a reformer, an afterburner and a heat exchanger. The aim of the invention is to increase the overall efficiency of high-temperature fuel cells. For this purpose, fresh air supplied to the fuel cell(s) on the cathode side is heated in several steps by means of a high-temperature heat exchanger with heat from post-combustion and from the heated air carried away from the fuel cell on the cathode side.
