| 摘要 |
A fuel cell power plant utilizing hydrogen and carbon oxide rich feed gas (4) and comprising a hydrogen-carbon oxide consuming fuel cell (2) with an anode compartment (2a) and a cathode compartment (2c), means for supplying feed gas (8, 10, 12) to the anode compartment (2a), compression means (41) for supplying the cathode compartment (2c) with compressed cathode oxidant gas (44), and means for recirculating fuel cell exhaust gas (46, 50, 42) to the cathode compartment (2c), which fuel cell power plant further comprises a methanation unit (9) for converting the hydrogen and carbon-oxide rich feed gas (4) into a methanated gas, a reforming catalyst bed (13) adapted to receive and reform the methanated gas to anode process gas (14) by absorbing waste heat from said fuel cell (2). |
