High-temperature operating fuel-cell module

A high-temperature operating fuel-cell module comprising:

• a fuel-cell stack that generates power by utilizing an electrochemical reaction of oxidant gas supplied to a cathode and reformed gas supplied to an anode;
• a fuel-cell stack container in which the fuel-cell stack is contained, cathode off-gas discharged from the cathode of the fuel-cell stack flowing in a space of the fuel-cell stack container in which the fuel-cell stack is contained;
• a cathode off-gas collector that is provided in the fuel-cell stack container, the cathode off-gas collector being a space in which the cathode off-gas is collected;
• an anode off-gas passage through which anode off-gas discharged from the anode of 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 that is a space in which the anode off-gas and the 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 collected in the cathode off-gas collector into the combustion chamber.
