Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings, but those skilled in the art understand that the present invention is not limited thereto.

[0034] Such as figure 1 and 2 As shown, the fuel cell system of the present invention includes an online hydrogen supply unit, a fuel cell unit and a water circulation unit.

[0035] Wherein, the online hydrogen supply unit is used to make the reactant block to be hydrolyzed to produce hydrogen contact with water to perform a hydrolyzed hydrogen production reaction to provide hydrogen; the reactant block 42 can be hydrolyzed and produced Those solid-phase objects that react with hydrogen, such as aluminum-gallium-based alloys or sodium borohydride, are preferably aluminum-gallium-indium-tin alloys.

[0036] In one embodiment, the online hydrogen supply unit includes a reaction vessel 4 and a hydrogen buffer vessel 5, wherein the reaction vessel 4 is used to contact the reactant...

Abstract

The invention discloses an on-line hydrogen supply fuel cell system based on water self-circulation. The fuel cell system comprises an on-line hydrogen supply unit which is used for contacting reactant blocks to be hydrolyzed for hydrogen production with water to carry out hydrolysis hydrogen production reaction to provide hydrogen; a fuel cell unit which is used for using the hydrogen from the on-line hydrogen supply unit as fuel and converting chemical energy of hydrogen and oxygen reaction into electric energy; and a water circulation unit which is used for recovering at least part of the water in the gas-water mixture discharged after the fuel cell unit generates electricity and sending the water as hydrolysis hydrogen production reaction water to the on-line hydrogen supply unit for recycling. According to the fuel cell system, the product water generated after electricity generation of the fuel cell through the hydrogen is recovered by the water circulation system and can participate in the hydrogen supply reaction again, thus reducing the raw water demand of the on-line hydrogen supply technology, reducing the volume and weight of the device and greatly improving the practicability and the portability of the on-line hydrogen supply power supply power system.

Description

technical field [0001] The invention relates to a fuel cell system for applying online hydrogen supply based on water self-circulation. Background technique [0002] As an efficient and pollution-free clean energy, hydrogen energy has been widely used in transportation, national defense industry, metal cutting and other fields. Hydrogen energy has the advantages of good combustion performance, high calorific value, non-toxic and non-polluting combustion products, high utilization rate, and can reduce the greenhouse effect. It is an efficient and clean energy that needs to be promoted and used in the world in the 21st century. [0003] The use of online hydrogen supply can avoid the storage and transportation of hydrogen, which is an effective solution. Among them, various metal powders represented by aluminum powder and sodium borohydride are the most common online hydrogen supply materials at present, but these materials have a fast hydrogen release reaction rate and are v...
