Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a protection mechanism for fuel cells. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. It is also called an electrochemical generator. It is the fourth power generation technology after hydroelectric power generation, thermal power generation, and atomic power generation. In addition, fuel cells use fuel and oxygen as raw materials and have no mechanical transmission parts, so they emit very little harmful gas and have a long service life.

[0003] In actual use, the existing fuel cells are installed without buffering in contact with the shell. When the shell is subjected to severe impact or vibration, the fuel cell is often impacted and may rupture. In addition, the fuel cell will release a large amount of heat during the conversion process, causing the fuel cell discharge power to decrease.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a protection mechanism for a fuel cell is proposed. Utility Model Content

[0008] Furthermore, the battery limiting assembly is provided with four groups, and the four limiting plates are respectively arranged on the front side, the rear side, the left side and the right side inside the battery protection box.

[0009] Furthermore, a movable slider is slidably connected inside the slide rail, and the vertical center axis of the limit plate is consistent with the vertical center axis of the positioning key.

[0010] Furthermore, the left and right ends of the balance board are fixedly connected to the adjustment seat, and the positioning hole is opened on the top outer wall of the battery mounting base.

The heat-conducting plate is in close contact with the outer wall of the fuel cell to conduct the heat generated during use, thereby accelerating the heat conduction rate. The heat-dissipating column increases the contact area between heat and air, thereby accelerating the heat exchange between heat and air. The rotation of the heat-dissipating fan drives the air flow inside the battery protection box.
