Abstract
The plant () with high-temperature fuel cells () includes a clamping device for a cell stack () and axially aligned chambers () for an after-burning. Clamping bars () of the clamping device are disposed between the afterburning chambers. Exhaust gas passages connect the after-burning chambers to a heat exchanger () acting as a heat sink. A clamping element () of the clamping device is in heat conducting connection with the heat exchanger. Compression springs () are respectively mounted on the clamping bars between an end of the clamping bar and a lug () of the clamping element. In this arrangement they exert a clamping force onto the clamping bars. The compression springs are shielded by the clamping element from the cell stack so that, thanks to the heat sink, the compression springs are only exposed to moderate temperature at which the clamping force is maintained.
