FUEL CELL POWER GENERATION SYSTEM WITH GASIFIER

摘要

A fuel cell system employs a thermally and chemically integrated gasification reactor. The fuel cell (1) converts a part of the gaseous fuel (12) passing through its cell structure to electricity and heat. A part of the depleted fuel (11) is fed into a gasification reactor (8) containing solid carbonaceous material (9). The anode exhaust gas (11) provides the chemical reactants for the gasification process. The anode exhaust gas (11) also provides all or part of the required heat for the endothermic gasification pro cess. The heat from the oxidant gas (5) and the exhaust gas (11) is transferred indirectly to the gasification reactor. The oxidant (5) does not enter the gasification reactor, unless required for heat balancing during operation of the system. A second fuel cell and/or and afterburner may optionally be provided downstream of the first fuel cell.
