As a clean power generation technology, fuel cells can be used as portable power generation equipment, but the fuel cell power generation process needs to consume hydrogen continuously. The common method is to carry hydrogen bottles or physical and chemical adsorption hydrogen storage equipment, but there are many methods for the above methods. Disadvantages: firstly, the safety is not high; secondly, the source of hydrogen is not solved, that is, the problem of hydrogen production

For the metal hydride hydrogen production system for portable power supply, the technical problems that need to be solved include: (1) The flow rate of the alkali metal borohydride solution supplied to the catalytic reactor needs to be adaptively and automatically controlled according to the change of the hydrogen consumption of the fuel cell (2) Direction independence, that is, the flow of the fluid in the system has nothing to do with the direction of the container; (3) The reaction waste is automatically recovered; (4) The fuel solution is fed and the reaction waste is discharged easily; (5) When the system is closed, the fuel The alkali metal borohydride solution in the container will slowly hydrolyze and release hydrogen, so the pressure in the container or system will continue to increase and cause safety problems, requiring an effective solution

[0005] The core of the technical solution of US Patent Publication No. US 2006 / 0236606 A1 is the use of gas permeable membrane technology. This solution proposes a conceptual design that requires the gas permeable membrane to be elastic and able to withstand pressure. The membrane needs to be sealed with a solid container Connection, the above requirements are extremely difficult to achieve technically, even if the design concept can be realized, the cost of its realization is very high, and the elastic gas permeable membrane ages quickly, so the service life is short
