FUEL CELL POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent precipitation of carbon at the fuel pole of an internal reforming solid electrolyte type fuel cell and prevent poisoning of the fuel pole by sulfide, in the fuel cell generation system having the internal reforming solid type electrolyte fuel cell.

SOLUTION: The fuel cell generation system (1) is constructed of a pre-reformer (5) and an internal reforming solid electrolyte type fuel cell (7) or the like. The pre-reformer (5) reforms hydrocarbon having two or more of carbons in the material gas into CH4. The pre-reformer (5) has a tube having a hollow part and a catalyst is provided in the hollow part. The catalyst is formed of a precious metal catalyst. The pre-reformer (5) is jointed to a fuel cell (7) by a jointing member (6) formed of Cu. The pre-reformer (5) is connected to a fuel chamber (39) of the internal reforming solid electrolyte type fuel cell (7) through a third passage (17).
