NOVELTY - The honeycomb-type hydrogen generator has a hydrogen-production cell (10), a unit (16) for supplying a fuel, a unit (17) for supplying an oxidizing agent, and a unit (23) for generating and removing hydrogen-containing gas from the fuel-electrode side. The hydrogen-production cell comprises, in a honeycomb form, reaction tubes comprising a cylindrical separating membrane (11), a fuel electrode (12) provided on the inner or outer side faces of the membrane, and an oxidizing electrode (14) provided on the other side face.    USE - For fuel cell power generators used for electric vehicles and submarine boats, and for hydrogen supply systems (all claimed).    ADVANTAGE - The honeycomb-type hydrogen generator produces hydrogen-containing gas at a low temperature using a compact structure. The energy required for modification is reduced. The need for a heat-insulating material for interrupting heat generated by the reformer is eliminated. The produced hydrogen-containing gas is supplied easily to a fuel cell without cooling and mixing of nitrogen.    DETAILED DESCRIPTION - The honeycomb-type hydrogen generator has a hydrogen-production cell (10), a unit (16) for supplying a fuel containing organic matter and water, a unit (17) for supplying an oxidizing agent, and a unit (23) for generating and removing hydrogen-containing gas from the fuel-electrode side. The hydrogen-production cell comprises, in a honeycomb form, reaction tubes comprising a cylindrical separating membrane (11), a fuel electrode (12) provided on the inner or outer side faces of the membrane, and an oxidizing electrode (14) provided on the other side face. Unit (16) supplies the fuel into the fuel electrode, and unit (17) supplies the oxidizing agent into the oxidizing electrode. A region where the amount of oxidizing agent supplied is insufficient, is provided on the oxidizing-electrode side.    INDEPENDENT CLAIMS are included for the following:    (1) fuel cell power generator;    (2) electric vehicle;    (3) submarine boat;    (4) hydrogen supply system; and    (5) reaction tube.
