Abstract

The invention relates to a leakage preventive hydrogen tank for a hydrogen-powered automobile, belongs to the technical field of new energy automobiles, and aims at solving the problem that a hydrogentank of a hydrogen-powered automobile in the prior art possibly leaks during use and potential risk is caused. The leakage preventive hydrogen tank for the hydrogen-powered automobile comprises an inner layer of the hydrogen tank, an outer layer of the hydrogen tank, a solid hydrogen storing material which is arranged between the inner layer of the hydrogen tank and the outer layer of the hydrogen tank, a hydrogen leakage detecting device and a data receiving and handling system, wherein the hydrogen leakage detecting device is used for detecting whether hydrogen leaks between the inner layerof the hydrogen tank and the outer layer of the hydrogen tank; and the solid hydrogen storing material is used for absorbing the possibly leaked hydrogen. With the adoption of the leakage preventivehydrogen tank for the hydrogen-powered automobile, the technical effects of detecting hydrogen leakage and preventing hydrogen from leaking into air can be achieved; the shortages in the prior art aresolved; and the leakage preventive hydrogen tank for the hydrogen-powered automobile has outstanding substantive characteristics and obvious progress.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a leak-proof hydrogen tank for hydrogen-powered vehicles. Background technique [0002] Hydrogen-powered vehicles are a typical type of new energy vehicles and belong to fuel cell vehicles. Hydrogen fuel cells are currently one of the most promising new-generation energy supply systems. They convert chemical energy into electrical energy efficiently and are widely used in aerospace. , automobiles and many other fields. [0003] Due to the active chemical nature of hydrogen, the storage of hydrogen has become the key to the application of hydrogen fuel cells. At present, the storage and transportation technology of hydrogen has been relatively perfect and has the conditions for production and application, but there are still problems such as poor safety, high price, and limited storage capacity. [0004] The hydrogen tank for storing hydrogen has a slow-release phenom...
