▎ 摘　　要

NOVELTY - Hydrogen fuel cell hydrogen supply system comprises first storage tank (1) for storing hydrogen storage material. A reactor (3) for receiving the hydrogen storage material from the storage tank and performing dehydrogenation reaction. A heat exchanger (2) for storing the hydrogen storage material in the first storage tank before entering the reactor, exchanging heat of the hydrogen storage material of the first storage tank and the material at the outlet of the reactor. A separation tank (4) for separating the hydrogen and the dehydrogenation material from the dehydrogenation reaction of the reactor. A second storage tank (5) for storing the dehydrogenation material separated from the separation tank. A buffer tank for storing the hydrogen separated from the separation tank and conveying to the hydrogen fuel cell. A hydrogen fuel cell, energy storage device for storing hydrogen fuel cell to generate a part of electric energy, and providing energy to the reactor. USE - Used as hydrogen fuel cell hydrogen supply system. ADVANTAGE - The system: combines the hydrogen fuel cell, dehydrogenation and energy storage device of the hydrogen storage material; considers the fuel cell working condition change, the fuel cell redundant energy for storage by flexible energy storage device; supplies hydrogen storage material dehydrogenation reaction process; has simple process, and high energy utilization rate; and is convenient operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for heat utilization method of hydrogen fuel cell hydrogen supply system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the hydrogen fuel cell hydrogen supply system.
