てなんら考慮されていなかつた。In the above prior art, a reaction tube is provided in the center of the fuel reformer, and combustion gas is circulated around the reaction tube to surround them with a heat insulating layer to prevent heat radiation. Since the two are adjacent to each other, the heat insulating layer becomes thick and the volume of the heat insulating layer occupying the fuel reforming portion is large. Further, since the combustion gas heats a large area inside the heat insulation layer, no consideration has been given to the loss of heat quantity of the combustion gas due to the heating.
