Abstract

The invention relates to an integrated hydrogen supply system for controllable hydrolytic hydrogen release for fuel cells, which comprises a hydrolytic hydrogen release unit, a control unit, a fuel cell unit and a hydrogen utilization unit, and is characterized in that a hydrogen output port of the hydrolytic hydrogen release unit is communicated with a gas path hydrogen input port of the control unit, a gas inlet of the fuel cell unit is communicated with a gas path output port of the control unit, the hydrogen utilization unit is in power output connection with the fuel cell unit, and the load of the hydrogen utilization unit should be matched with the power of the fuel cell unit. The integrated hydrogen supply system has multiple paths for hydrogen supply which can be independently used or be simultaneously used to increase the amount of hydrogen supply and can also serve as gas storage tanks to increase the reliability of the whole system. The on-off, namely, the proceeding and stopping of reaction, of the hydrogen supply system and the on-off of fuel cells of the hydrogen utilization system can be controlled at any time and place.

Description

technical field

[0001] The invention belongs to the technical field of gas supply, and in particular relates to an integrated hydrogen supply system for a controllable hydrolysis hydrogen supply suitable for a fuel cell. Background technique

[0002] "Hydrogen" has long been considered an ideal secondary energy source because of its abundance, pollution-free and renewable, and high energy density. However, hydrogen energy is limited in terms of hydrogen production, hydrogen storage and hydrogen transportation. The above-mentioned problems can be avoided by realizing the integration of hydrogen supply. Hydrogen fuel cell is known as the fourth-generation power generation technology after hydropower, thermal power, and nuclear power. It can convert hydrogen energy into electrical energy in real time and its power generation is not limited by the Carnot cycle. The power generation efficiency can reach 85-90%. It is 2 to 3 times higher than domestic internal combustion engines...
