[0002] The packaging structure of an air-cooled fuel cell system refers to a series of protective and functional combination architectures designed to ensure that the air-cooled fuel cell can operate stably and efficiently. It usually includes a shell, sealing components, fixing devices and connecting components. The shell plays a physical protection role to prevent the external environment from damaging the fuel cell. The sealing components ensure that the working environment inside the fuel cell is not disturbed by the outside world and maintain the sealing of gases and liquids. The fixing devices enable the various components inside the fuel cell to be firmly placed in a predetermined position to avoid performance affected by vibration or displacement. The connecting components are responsible for achieving effective connection between the fuel cell and external circuits, pipelines, etc. to ensure the output of electrical energy and the transmission of working media.

[0003] Nowadays, air-cooled fuel cell stacks suffer serious performance loss when stored for a long time. After a period of storage, it takes an extremely long time to reach the rated power when restarted. In the current industry, the commonly used solution is regular startup. However, this method has obvious drawbacks. The startup problem of air-cooled fuel cell stacks has always been a major test faced by the entire industry, especially in low-temperature environments and low-power operation conditions. How to make the air-cooled fuel cell stack reach the target temperature smoothly is an extremely challenging problem. Utility Model Content
