Abstract

The invention provides a hydrogen supply system and a hydrogen supply method. The hydrogen supply system comprises a raw material supply unit, a hydrogen production unit and a separation unit which are connected in sequence. The hydrogen supply system further comprises a control unit used for controlling the hydrogen generation rate, and the control unit is electrically connected with the raw material supply unit and the hydrogen generation unit. Based on a formic acid catalytic hydrogen production principle, formic acid is decomposed to generate carbon dioxide and hydrogen under the action ofa catalyst, and compared with a hydrogen supply system utilizing hydrogen in a gas storage tank, the hydrogen supply system provided by the invention has the advantages that the hydrogen generation rate is controlled through the control unit, hydrogen can be produced and used immediately without being stored in a high-pressure storage tank, and the danger of hydrogen leakage or hydrogen storage tank explosion is avoided. Besides, the hydrogen production raw material (namely formic acid) is stored by adopting the raw material supply unit, a storage place and a reaction place of the hydrogen production raw material are separated, and a continuous and controllable hydrogen production process is realized under the control of the control unit.

Description

technical field [0001] The invention belongs to the technical field of gas generation, and relates to a hydrogen supply system and a hydrogen supply method, in particular to a hydrogen supply system and a hydrogen supply method which adopt a control unit to control the hydrogen generation rate. Background technique [0002] Hydrogen is an important clean energy. But hydrogen is difficult to liquefy and difficult to store. Traditional hydrogen production methods include electrolysis of water hydrogen production method, water gas hydrogen production method, catalytic reforming hydrogen production method, etc. However, the equipment used in these hydrogen production methods is complex in structure, bulky, difficult to miniaturize, and often requires hydrogen tanks for supporting use. [0003] CN206817171U discloses a vehicle-mounted hydrogen supply system suitable for fuel cell electric vehicles. The hydrogen supply system includes a bracket for placing gas cylinders and a fi...
