TECHNICAL FIELD

[0001] The present application relates to the technical field of fuel cell systems, specifically, a frame fixing structure of a fuel cell system. BACKGROUND

[0002] In recent years, hydrogen fuel cell systems have been increasingly widely used in commercial vehicles, locomotives, power stations and other fields due to their advantages of high efficiency, environmental protection and the like. However, with the diversification of application scenarios, the traditional fixing method of commercial vehicles has been difficult to adapt to the space layout and installation requirements in different fields. For example, the space in scenarios such as locomotives and power stations is more strictly limited, and higher requirements are put forward for the integration and maintainability of the system.

[0003] At present, for hydrogen fuel cell systems in different application scenarios, a customized fixing scheme is usually adopted, which leads to a long design cycle, high development cost, and difficulty in realizing platform application. In addition, the traditional fixing structure is often not conducive to after-sales maintenance, increasing the difficulty and cost of maintenance. Therefore, a fixing scheme with strong universality, high integration and easy maintenance is urgently needed to meet the needs of multi-field applications and reduce production and maintenance costs.
