Abstract
The invention relates to a high-temperature fuel cell system which can be operated with at least one hydrocarbon compound, preferably with methane or a gas containing methane such as natural gas or biogas. It is the object of the invention to increase the efficiency of high-temperature fuel cell systems and to allow a more flexible operation. In the system in accordance with the invention, individual fuel cells are present which are connected electrically in series and form the stacks. The stacks are flowed through after one another by fuel gas which contains hydrogen and which flows into a first stack of the system from a reformer and a suitable hydrocarbon compound is supplied via further connection lines in the flow direction of the introduced fuel gas sequentially into further stacks to the respective stack for a direct internal reforming of a hydrocarbon compound at anodes of the fuel cells of the stack and air is supplied as an oxidation means at the cathode side to the individual fuel cells of the system.
