Power station with high-temp fuel cell (HTFC) stack and gas treatment plant

摘要

A power generating plant having at least two fuel-cell stacks in which the first stack (1) comprises an internal or an external reformer thermally coupled on to the stack and with at least one gas treatment plant (10) arranged in the combustion gas feed line of the second stack (2). At least three further lines are provided next to the usual output and/or the anode chamber input of the first stack (1) to the input of the gas treatment-plant (10), a second line (9) joining the latter's output to the combustion gas line of the first and/or second stack (1,2) and a third line (5) joining the output of the anode chamber of the second stack to the combustion gas line (14) of the first stack and/or to the first line (4). A further line (6) is specifically provided and joins the cathode off-gas to the oxidant feed line (8) of the first stack so that the off-gas is fed out of the cathode space into the oxidant in feed line (8).
