<P>PROBLEM TO BE SOLVED: To provide a reformer in which a heat transfer area and an evaporator area of an evaporator container are formed large and a water volume of the evaporator is made large to enable the stable supply of steam. <P>SOLUTION: A burner, a heat transfer tube, a catalyst tube filled with a catalyst, and an evaporator container are arranged centered on a burner in a concentric shape to the center axis of the burner in a reformer of the fuel cell. A steam exhaust tube to take out steam from the evaporator container is arranged outside the evaporator container. The heat transfer tube heats the catalyst tube and the evaporator, and by mixing hydrocarbon at the exit of the steam exhaust tube, the mixed gas is introduced into the catalyst layer to carry out reforming reaction. The evaporator container has a vertical portion surrounding the burner and a horizontal portion which is inclined extending in horizontal direction at the surrounding of the burner. <P>COPYRIGHT: (C)2007,JPO&INPIT |
