[0002] As a commonly used energy supply component in modern times, the main function of hydrogen fuel cells is to be installed inside a vehicle, generate electricity through the combustion of hydrogen fuel, and transmit the electricity to the inside of an external vehicle to drive the vehicle. In the existing hydrogen fuel cell production process, it is often necessary to install a shell on the outer surface of the hydrogen fuel cell to protect the hydrogen fuel cell and fix the hydrogen fuel cell to the outer surface of an external fixed platform. However, the existing hydrogen fuel cell shell lacks protective auxiliary components. During the use of the hydrogen fuel cell shell, it is impossible to buffer and protect the hydrogen fuel cell, resulting in damage to the hydrogen fuel cell due to external impact, which in turn affects the user experience of the hydrogen fuel cell.

[0003] Compared with the existing hydrogen fuel cell housing, the utility model adds protective auxiliary components. During the use of the hydrogen fuel cell housing, when the impact force is transmitted to the inside of the hydrogen fuel cell housing through the shock-absorbing layer and the shock-absorbing frame, the impact force can be partially absorbed, preventing the hydrogen fuel cell from a hard collision with the external housing, thereby improving the safety of the hydrogen fuel cell housing.

[0006] The outer surface of the partition is wrapped and connected with a shock-absorbing layer, and the outer surface of the shock-absorbing layer is installed with two groups of shock-absorbing frames.

[0007] Preferably, a plurality of conveying holes are formed through the top of the fixing plate.

[0008] Preferably, ventilation shells are installed on both sides of the fixed shell.

[0009] Preferably, a shielding rod is installed on the inner side of the ventilation shell, and an intercepting net is installed on the inner side of the ventilation shell through a connecting frame, and the intercepting net is located on one side of the shielding rod.

[0011] Preferably, two groups of fixing plates are installed on both sides of the fixing shell, and threaded sleeves are installed through the interior of the fixing plates.

[0012] Preferably, a plurality of ventilation holes are formed through the outer surface of the partition.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is equipped with a shock-absorbing layer and a shock-absorbing frame. The shock-absorbing layer is installed on the outer surface of the partition and is made of sponge material. When the impact force in the external environment is transmitted to the inside of the shock-absorbing layer, the shock-absorbing layer undergoes elastic deformation to preliminarily absorb the impact force to prevent the hydrogen fuel cell from colliding with the partition. The shock-absorbing frame is installed on the outer surface of the shock-absorbing layer and is made of rubber material. When the impact force in the external environment is transmitted to the inside of the shock-absorbing frame, the shock-absorbing frame undergoes elastic deformation to further absorb the impact force to prevent the hydrogen fuel cell from colliding with the fixed shell and the fixed plate, thereby improving the safety of the hydrogen fuel cell.
