NOVELTY - The apparatus comprises a reactor, a heater (20) having a first portion that is located in the reactor, a dehydrogenation catalyst (21) affixed to the first portion of the heater, a hydrogen release conduit (16) present in communication with the reactor and a fuel cell (32), a chamber (12) containing a hydrogenated carrier (14), an energy source coupled to the heater, a unit for engaging the hydrogenated carrier with the dehydrogenation catalyst, a spent carrier reservoir present in communication with the hydrogenated carrier, and an electrical connection.    USE - The hydrogen storage apparatus is useful for releasing stored hydrogen from a liquid or solid carrier, where the hydrogen is useful as a fuel source in hydrogen powered vehicle and the apparatus is a cartridge such as a power pack for an electric drill.    ADVANTAGE - The hydrogen storage apparatus has lightweight, and is capable of simply and efficiently releasing the hydrogen with high purity in the fuel cell.    DETAILED DESCRIPTION - The apparatus comprises a reactor, a heater (20) having a first portion that is located in the reactor, a dehydrogenation catalyst (21) affixed to the first portion of the heater, a hydrogen release conduit (16) present in communication with the reactor and a fuel cell (32), a chamber (12) containing a hydrogenated carrier (14), an energy source coupled to the heater, a unit for engaging the hydrogenated carrier with the dehydrogenation catalyst, a spent carrier reservoir present in communication with the hydrogenated carrier, and an electrical connection between the fuel cell and the heating element. The engagement unit comprises a collapsible bladder, and a pump. A capillary comprises the reactor and the engagement unit. The heater comprises a gas permeable and liquid impermeable material surrounding an interior channel. The interior channel is present in communication with the hydrogen release conduit. The energy source comprises electricity from a fuel cell, and heat from a chemical reaction. The reactor comprises hydrogen release openings located around a perimeter of the reactor, and a region located within the chamber, and is external to the chamber. Each of the hydrogen release openings is present in communication with the hydrogen release conduit. The spent carrier reservoir is adapted to receive the hydrogenated carrier after the hydrogenated carrier is passed through the reactor. The hydrogenated carrier is adapted to release hydrogen, when the carrier is heated to a temperature of greater than 100 degrees C. An INDEPENDENT CLAIM is included for a method for storing and releasing hydrogen.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a cartridge.
