A hydrogen energy fuel cell with self-protection function

Abstract

The invention discloses a hydrogen energy fuel cell with self-protection function, comprising a shell, a storage cavity is arranged in the shell, a hydrogen storage tank is stored in the storage cavity, a through cavity is communicated with an inner wall of one side of the storage cavity, and the through cavity is An air supply assembly is provided, a fusible plug is placed at one end of the storage cavity, a detection assembly is arranged between the inner wall of the storage cavity and the fusible plug, and a first cavity is opened at one end of the shell, and the shell is located on the lower side of the first cavity A second cavity is opened, and a baffle assembly is arranged in the second cavity. The baffle assembly can isolate the second cavity. A temporary storage cavity is arranged in the shell and located on the upper side of the storage cavity, and the temporary storage cavity is filled with Inert gas, the present invention preliminarily protects the hydrogen storage tank by adding inert gas around the hydrogen storage tank to prevent it from reacting with oxygen, and at the same time, while the hydrogen is rapidly released to the outside world, a large amount of inert gas is mixed into the hydrogen. , to achieve the dilution effect, so that the reaction with oxygen in the air can be reduced when it is discharged to the outside world.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy cells, in particular to a hydrogen energy fuel cell with a self-protection function. Background technique [0002] Compared with pure electric vehicles, hydrogen energy batteries have obvious advantages and disadvantages. Hydrogen energy batteries last longer than lithium batteries and are more environmentally friendly. However, compared with stability, lithium batteries are more stable than hydrogen energy. The battery is stronger. During the development of hydrogen energy batteries, spontaneous combustion of hydrogen energy vehicles and explosions of hydrogen refueling stations will occur. However, for hydrogen storage tanks that can be used in vehicles, they have strong stability and can store The hydrogen tank itself is well protected. In the event of a hydrogen leak, the hydrogen will be discharged to the outside in a very short time. However, there are hidden dangers in this method. ...

Problems solved by technology

[0002] Compared with pure electric vehicles, hydrogen energy batteries have obvious advantages and disadvantages. Hydrogen energy batteries last longer than lithium batteries and are more environmentally friendly, but compared to stability, lithium batteries are more stable than hydrogen energy batteries. The battery is stronger. In the process of hydrogen energy battery development, hydrogen energy vehicles will spontaneously ignite and hydrogen refueling stations will explode. However, for hydrogen storage tanks that can be used in vehicles, they are more stable and The protection of the hydrogen tank itself is good. When a hydrogen leak occurs, the hydrogen will be discharged to the outside in a very short time. However, there are hidden dangers in this method. When the hydrogen is discharged to the outside, it is easy to chemically react with the oxygen in the outside air, resulting in flames. , and hydrogen will explode when exposed to an open flame
