Description

Technical Field

[0001] The utility model relates to the technical field of test benches, and more particularly to a fuel cell stack test bench. Background Art

[0002] In existing technologies, existing test benches have obvious deficiencies in height adjustment. The fixed height design severely limits the adaptability of the test bench and cannot meet the testing requirements of fuel cell stacks of different sizes and types. This limitation not only increases the difficulty of the operator's work, but may also affect the accuracy of the test.

[0003] Secondly, the existing test bench lacks flexibility in battery fixing, which is another urgent problem that needs to be solved. The lack of an effective adjustable fixing mechanism means that the test bench is difficult to adapt to fuel cell stacks of different sizes, shapes and structures. The limitations of this fixing method not only increase the time and complexity of replacing and installing battery stacks, but may also affect the accuracy of the test.

[0004] Finally, existing test benches have limited capabilities for conducting pressure tests, which severely restricts the comprehensive evaluation of fuel cell stack performance. Pressure testing is a key step in evaluating the performance and durability of fuel cell stacks, but existing equipment often lacks flexible and precise pressure control mechanisms. This limitation makes it difficult for researchers to simulate the performance of fuel cells under different operating conditions, especially in extreme or changing pressure environments.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a fuel cell stack test bench with the following beneficial effects:

[0018] 1. The height adjustment assembly achieves precise height adjustment through the ingenious coordination of the fixed platform, mobile platform, bolts, rotating rod, rotating handle and worm gear. The meshing design of the half gear and worm gear provides a stable transmission mechanism, while the combination of the connecting rod, mobile wheel and triangular plate ensures a smooth lifting process. The connection between the mobile rod and the operating panel further optimizes the adjustment accuracy. This design not only improves the adaptability of the test bench and can accommodate fuel cell stacks of different sizes, but also greatly enhances the convenience and safety of operation.

[0019] 2. The fixing assembly adopts a combination design of a fixing plate, a fixing rod and a first spring, which greatly improves the fixing effect and flexibility of the fuel cell stack. The design of the pull plate and handle enables the operator to easily adjust the fixing force, while the addition of the second spring and the buffer plate provides buffer protection, effectively preventing damage to the fuel cell stack. This elastic fixing mechanism can not only adapt to fuel cell stacks of different sizes and shapes, but also provide continuous and stable pressure during the test. At the same time, the design also facilitates the rapid replacement and adjustment of the fuel cell stack, improving the test efficiency. The overall design of the fixing assembly fully considers the operational convenience and safety, providing reliable support for fuel cell stack testing.

[0020] 3. The pressure assembly realizes precise and controllable pressure testing function through the combination of mounting plate, top plate and cylinder. The design of guide rod ensures the stability and accuracy of the pressure plate during movement, effectively preventing deviation and tilt. The cylinder-driven pressure plate can provide continuous and stable pressure, making the test process more accurate and reliable. This design can not only simulate the performance of fuel cell stacks under different pressure conditions, but also perform pressure resistance tests, providing important support for performance evaluation and quality control of fuel cell stacks. The addition of the pressure assembly significantly improves the functionality of the test bench, enabling it to conduct more comprehensive and in-depth fuel cell stack performance analysis.
