For application scenes of a small air-cooled fuel cell system with the power of less than 5kW, such as a base station standby power supply, a low-speed two-wheel vehicle, a portable power supply and the like, the scenes need relatively convenient application experience, and convenient maintenance and quick replacement are needed.
For example, the present invention disclosed in publication No. CN107264710A provides a saddle-ride type vehicle having an air-cooled fuel cell unit mounted on a vehicle body frame behind a vertical pipe and in front of a pivot frame, the fuel cell unit having an intake port for taking in outside air toward the front below the vertical pipe and an exhaust port toward the rear above the pivot, and being used for supplying oxygen and cooling equipment, the seat frame being attached to a main frame and having a shell structure having a shape of an exhaust pipe for guiding exhaust gas discharged from the fuel cell unit to the rear of a passenger seat.
On the other hand, when the cathode open-air-cooled fuel cell system utilizes the fan to dissipate heat, the air flow flowing to different areas through the fan is not uniformly distributed, so that the inside of the cell module is easily subjected to local overheating, the performance of the cathode open-air-cooled fuel cell system is greatly reduced after the cathode open-air-cooled fuel cell system operates for a period of time, and the normal use of the cathode open-air-cooled fuel cell system is influenced.
For example, the patent application with publication number CN111477915A discloses a cathode open air-cooled fuel cell system, which includes a cell assembly, a fan assembly and a spoiler, wherein the fan assembly and the cell assembly are arranged at an interval, and the fan assembly is used for drawing an air flow to the cell assembly so as to make the air flow exchange heat with the cell assembly; the spoiler sets up between battery pack and fan assembly, and the spoiler is used for just disturbing the air current that flows to battery pack through fan assembly suction to the distribution homogeneity of the air current of each different region of reinforcing flow direction battery pack. However, the spoiler disclosed in the above-mentioned prior art has room for improvement.
