A power generation system with flat fuel cells of solid electrolyte of simple construction permissible of building up a large capacity system, which comprises a train of pile units (5) of flat fuel cells of solid electrolyte disposed in a horizontally extending fuel gas duct (1) adapted to supply said train of pile units of flat fuel cells with the fuel gas (103). each of said pile units of flat fuel cells having, on the one hand, horizontal flat flow paths for the fuel gas each disposed above each fuel-side porous electrode sheet and opening freely at both path ends on the opposing side faces of the pile unit and, on the other hand, horizontal flat flow paths for the oxidant gas each disposed beneath each oxygen-side porous electrode sheet separately from the fuel gas flow paths and each connected at both path ends to either a supply line (109) or to an exhaust line (L) for the oxidant gas, an after-burning region (125) disposed downstream of said train of pile units of flat fuel cells for burning at least a part of the spent fuel gas which has passed through the fuel cell using at least a part of the spent oxidant gas which has passed through the fuel cell, for generating a heat of combustion for use for preheating at least either one of the feed gases to be supplied to the fuel cell. <IMAGE> |
