NOVELTY - A hydrogen supply-storage apparatus (1) has a raw material tank (2), reaction container (3), and recovery tank (4) at the exit side of container. The container is at sufficient temperature for raw material to contact the catalyst (13) by passing through the interval of the catalyst in a gaseous state. The catalyst required for dehydrogenation or hydrogenation is packed in the path in which the raw material goes.    USE - For supply-storage of hydrogen (claimed), for use as fuel for motor vehicles.    ADVANTAGE - The novel hydrogen supply-storage apparatus suppresses evaporation of hydrocarbon group substance, and improves the reaction efficiency of hydrogenation and dehydrogenation. The waste heat derived by combustion of raw material is used effectively.    DETAILED DESCRIPTION - The hydrogen supply-storage apparatus (1) supplies hydrogen by dehydrogenation of hydrogen supply material which discharges hydrogen, or stores hydrogen by hydrogenation of hydrogen storage material bonding with hydrogen. The apparatus has a raw material tank (2), a reaction container (3), and a recovery tank (4) at the exit side of the reaction container. The raw material tank stores the hydrogen supply material or the hydrogen storage material. The reaction container is at a sufficient temperature for the raw material to contact the catalyst (13) by passing through the interval of the catalyst in a gaseous state. The catalyst required for dehydrogenation or hydrogenation is packed in the path in which the raw material goes from the inlet to the exit. The reaction container includes a heater (11) for heating the catalyst. The recovery tank recovers the product of dehydrogenation or hydrogenation. The catalyst is platinum, palladium, ruthenium, iridium, rhenium, nickel, molybdenum, tungsten, vanadium, osmium, chromium, cobalt and/or iron.    An INDEPENDENT CLAIM is included for a hydrogen supply-storage method.
