Description

Technical Field

[0001] This utility model relates to the field of titanium alloy fuel cell technology, specifically to a cathode-enclosed titanium alloy fuel cell structure. Background Technology

[0002] In recent years, with the booming development of the hydrogen energy industry, fuel cell stacks have become a key development direction. Fuel cell stacks are developing towards higher power, longer lifespan, and higher power density. In high-power stacks, the number of bipolar plates is increasing. Because there is a sealed elastic structure between the bipolar plates, the more layers there are, the worse the internal stability of the stack becomes, which brings many problems and affects the performance and lifespan of the stack. Continuous improvement is still needed.

[0003] However, it still has some drawbacks. For example, the fuel cell stack consists of many layers of bipolar plates, insulating gaskets, and insulating plates, sometimes numbering in the hundreds. These layers are sealed with adhesive lines and other sealing structures. However, since each layer is independent, the fuel cell stack will inevitably experience collisions during use. These collisions can cause deformation of the stack, affecting its performance and the sealing structure, leading to leaks and, in severe cases, even safety accidents.

[0004] To address the aforementioned issues, this application proposes a cathode-enclosed titanium alloy fuel cell stack structure. Utility Model Content

[0005] The purpose of this invention is to provide a cathode-enclosed titanium alloy fuel cell stack structure to address the problems mentioned in the background section of the prior art, where the fuel cell stack consists of numerous layers of bipolar plates, insulating gaskets, and insulating plates, sometimes numbering in the hundreds. These layers are sealed with adhesive lines, but because each layer is independent, the fuel cell stack inevitably experiences collisions during use. These collisions can cause deformation of the stack, affecting fuel cell performance and the sealing structure, leading to leaks and, in severe cases, even safety accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cathode-enclosed titanium alloy fuel cell stack structure, including a fuel cell stack, an insulating partition between each group of fuel cell stacks, anti-collision plates fixedly connected to the outer surfaces of the front and rear ends of the fuel cell stack, a connecting block fixedly connected to the upper outer surface of the anti-collision plate, and end plate one and end plate two fixedly connected to the outer surfaces of the left and right sides of the fuel cell stack, with end plate one located on one side of end plate two.

[0007] Preferably, a connecting plate is provided between each group of connecting blocks, and a slot is provided on the upper outer surface of the connecting plate. A conical block is provided between the connecting plate and the connecting block.

[0008] Preferably, the upper outer surfaces of the first end plate and the second end plate are provided with positioning grooves, one outer surface of the first end plate and the second end plate is provided with a groove, and a conical locking block is engaged on the inner surface of the positioning groove, and a fixing bolt is provided on the inner surface of the groove, and the fixing bolt passes through one outer surface of the second end plate.

[0009] Preferably, the outer surface of one side of the conical block has a threaded hole, and the threaded hole is threadedly connected to the fixing bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, through the inclusion of anti-collision plates, prevents the fuel cell stack from being damaged during collisions, thereby reducing the occurrence of fuel cell stack deformation and leakage, and providing protection for the fuel cell stack.

[0012] This invention, through the design of conical locking blocks one and two, allows us to easily and evenly stack each group of fuel cells together, preventing displacement of each group of fuel cells in the event of a collision. At the same time, it allows for quick positioning and assembly during the assembly process, making the operation convenient and simple, and resulting in better stability of the assembled fuel cells.
