PURPOSE:To provide the title reformer so designed that a plurality of catalyst beds are multicylindrically formed and heating beds are located between adjacent catalyst beds so that both the beds are each alternately arranged, thereby making the whole system compact and improving catalyst packing efficiency leading to increasing thermal efficiency. CONSTITUTION:A fuel gas vaporized at an evaporator 1 is collected to a collection chamber 8, distributed into respective catalyst tanks 3a, 3b, and reacted during descending through these catalyst beds into a reformed gas consisting mainly of hydrogen gas. This gas is then collected to a second collection chamber 9 and then fed via a pipe 10 into a fuel cell main body. The heating gas generated by a burner 2 partly enter a heating bed 5a, another part thereof entering a heating bed 5b through the space between a reaction vessel 3a and the collection chamber 9, and a third part entering a heating bed 5c through communicating ports 11 provided on the outer peripheral side of the collection chamber 9. The heating gas then rises up through the heating beds 5a-5c so as to be put to countercurrent to the reaction gas in the catalyst beds 4a, 4b, and then exhausted via an exhaust pipe 12. |
