[0002] The hydrogen fuel cell stack is the core component of the hydrogen fuel cell system, and its technical level directly affects the overall performance of the battery system, hydrogen fuel cell vehicles, and other hydrogen fuel cell equipment. Currently, with the rapid development of hydrogen fuel cell stack technology, hydrogen fuel cell stack performance has greatly improved. Existing single-unit stack power can reach over 260kW, and the stack height has also increased to over 1000mm. Therefore, the stability of the stack during and after assembly is crucial.

When the stack is tall, the positioning rods are prone to bending, making it difficult to ensure the overall stability of the high-power stack. Furthermore, due to machining errors in the positioning holes, the positioning rods are difficult to remove after assembly. Furthermore, after assembly, the stack still requires a press, which can cause stress and deformation under different operating conditions, directly impacting the safety and service life of the stack.
