Hydrogen energy fuel cell with self-protection function

Abstract

The invention discloses a hydrogen energy fuel cell with a self-protection function. The hydrogen energy fuel cell comprises a shell, a storage cavity is formed in the shell, a hydrogen storage tank is stored in the storage cavity, the inner wall of one side in the storage cavity is communicated with a through cavity, an air supply assembly is arranged in the through cavity, a fusible plug is placed at one end in the storage cavity, a detection assembly is arranged between the inner wall of the storage cavity and the fusible plug, a first cavity is formed in one end in the shell, a second cavity is formed in the position, located on the lower side of the first cavity, in the shell, a baffle assembly is arranged in the second cavity and can isolate the interior of the second cavity, a temporary storage cavity is formed in the position, located on the upper side of the storage cavity, in the shell, and the temporary storage cavity is filled with inert gas. The hydrogen storage tank is primarily protected by adding inert gas around the hydrogen storage tank, the hydrogen storage tank is prevented from reacting with oxygen, a large amount of inert gas is mixed into the hydrogen while the hydrogen is rapidly released to the outside, the dilution effect is achieved, and therefore when the hydrogen is discharged to the outside, the reaction of the hydrogen with the oxygen in the air can be reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy cells, in particular to a hydrogen energy fuel cell with 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, 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 ...

[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
