Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a hydrogen fuel cell safety protection device for a hydrogen hybrid commercial vehicle, which can buffer and protect the battery stack body by using the water produced during the battery stack operation, and can also assist in cooling the battery stack. At the same time, it can also filter the air entering the battery stack, effectively protect the fuel cell and other advantages, and solve the problem that when the ambient air is poor, there are still more particles that are compressed and transported into the battery stack. Seriously affects the service life of the battery stack. In addition, the battery stack is mostly directly assembled on the vehicle body, which produces a large vibration when the vehicle moves, which is not conducive to the safe use of the battery stack.

Description

technical field [0001] The invention relates to the technical field of fuel cell accessories, in particular to a hydrogen fuel cell safety protection device for a hydrogen-energy hybrid commercial vehicle. Background technique [0002] The working principle of a hydrogen fuel cell vehicle is to send hydrogen to the anode plate of the fuel cell. After the action of the catalyst, an electron in the hydrogen atom is separated, and the hydrogen ion that has lost the electron passes through the proton exchange membrane and reaches the cathode plate of the fuel cell. Electrons cannot pass through the proton exchange membrane. The electrons can only pass through the external circuit to reach the cathode plate of the fuel cell, thereby generating current in the external circuit. After the electrons reach the cathode plate, they recombine with oxygen atoms and hydrogen ions to form water. The oxygen supplied to the cathode plate can be obtained from the air, so as long as hydrogen is...
