Water recovery type NaBH4 hydrogen production device

Abstract

The invention discloses a water recovery type NaBH4 hydrogen production device which comprises a recovery container, a liquid preparation container, a liquid storage container, a reactor and a timing switch control unit, the recovery container is communicated with the fuel cell two-way pipeline; the recovery container is communicated with the liquid preparation container through a water inlet pipeline; the water inlet pipeline is also provided with a first pump; the liquid preparation container is communicated with the liquid storage container through a liquid discharge pipeline, and the liquid discharge pipeline is also provided with a second pump; the liquid storage container is communicated with the reactor through a liquid inlet pipeline; the reactor is communicated with a recovery container pipeline; the timing switch control unit controls on-off of the first pump and the second pump. According to the invention, fuel cell cathode reaction water is recovered through a fuel cell reaction water recovery mode, and the recovered water is used as a hydrolysis reaction raw material and a hydrolysis reaction hydrogen product cleaning solution; and the hydrolysis catalytic reactor and the radiator are integrated, so that the light weight effect is achieved, the weight of the NaBH4 hydrogen production device is reduced, and the hydrogen storage density of the device is effectively improved.

Description

technical field [0001] The invention belongs to the field of hydrogen production devices, in particular to a water recovery NaBH 4 Hydrogen plant. Background technique [0002] Due to its advantages of high energy density, low noise, no pollution, high efficiency, long life, low infrared radiation and electromagnetic radiation, hydrogen fuel cells are gradually being applied in aerospace and military fields, but due to the problem of hydrogen sources, hydrogen fuel cells have not been Effectively solve and limit its further supporting development. [0003] For small aerospace military equipment, compared with other hydrogen storage methods, NaBH 4 Hydrogen production by hydrolysis has the advantages of high hydrogen purity, high energy utilization rate, high safety, and recyclable by-products. According to 35% saturated NaBH 4 The theoretical material hydrogen storage density of the solution is 7.56%, but the current NaBH 4 The hydrogen storage density of the aqueous sol...

[0003] For small aerospace military equipment, compared with other hydrogen storage methods, NaBH 4 Hydrogen production by hydrolysis has the advantages of high hydrogen purity, high energy utilization rate, high safety, and recyclable by-products. According to 35% saturated NaBH 4 The theoretical material hydrogen storage density of the solution is 7.56%, but the current NaBH 4 The hydrogen storage density of the aqueous solution hydrogen production device can only reach about 3wt%, which has no advantages compared with the high-pressure gas hydrogen storage system
