Abstract: A high-temperature operating fuel-cell module includes a fuel-cell stack; a fuel-cell stack container in which the fuel-cell stack is contained and cathode off-gas discharged from the fuel-cell stack flows; a cathode off-gas collector that is provided in the fuel-cell stack container and in which the cathode off-gas is collected; an anode off-gas passage through which anode off-gas discharged from the fuel-cell stack flows; and a combustor that combusts the cathode off-gas collected in the cathode off-gas collector and the anode off-gas flowing through the anode off-gas passage, the combustor comprising: a combustion chamber in which the anode and cathode off-gas are mixed and combusted, an ejector that is connected to the anode off-gas passage and ejects the anode off-gas into the combustion chamber, and a diffusion plate that surrounds the ejector so that the ejector is located at the center of the diffusion plate, and ejects the cathode off-gas into the combustion chamber.
