  The reforming unit has a structure including a vaporizer that vaporizes the hydrogen raw material and a catalyst layer that reforms the hydrogen raw material vaporized by the vaporizer. When kerosene is used as the hydrogen raw material, the reforming unit includes Requires an operating temperature of approximately 800 ° C. Therefore, a combustion part (combustion device) for heating the reforming part is indispensable for the purpose of maintaining the operating temperature at the start of the fuel cell and during the power generation operation.

  As shown in FIG. 4, the combustion section (combustion device) raises the temperature of the reforming section by burning hydrocarbon fuel such as kerosene when starting the fuel cell, and discharges it from the hydrogen electrode of the fuel cell during power generation operation. The reformed part is maintained at a predetermined temperature by burning the hydrogen electrode exhaust gas (off-gas) as fuel.

For example, as shown in Japanese Patent Application Laid-Open No. 2007-120856, this combustion apparatus has a flame plate disposed in a burner cylinder so as to close the upper part of the burner cylinder, and combustion gas and primary air vaporized by a vaporizer A mixed gas supply section for supplying a mixed gas for combustion onto the flame plate is provided so as to communicate with a mixed gas injection hole provided at the center of the flame plate, and this mixed gas for combustion is jetted onto the flame plate.

It is configured to be supplied onto the flame plate and burned reliably.

  The exhaust gas supply unit is not provided directly on the flame plate, but is provided through an exhaust gas chamber so that exhaust gas is uniformly ejected from each of the exhaust gas ejection holes provided in a large number so as to surround the mixed gas ejection hole at the center of the flame plate. As a configuration, the exhaust gas is jetted onto the flame plate from the exhaust gas jet hole through the exhaust gas chamber from the exhaust gas supply unit.

  Specifically, the exhaust gas chamber forming member provided with a cup-shaped exhaust gas chamber forming recess is welded to the lower surface of the flame plate so that the upper opening of the recess communicates with the exhaust gas ejection hole of the flame plate. The exhaust gas supply unit is continuously provided in the recess, and the mixed gas supply unit is provided through the center of the recess.
