Problems solved by technology
However, this method takes up a lot of hardware resources for the speed regulation signal of the fan speed regulation control system, and needs to customize the development of the controller, which increases the cost
In addition, the flow trajectory of the coolant of the existing fuel cell inside the fuel cell is a serpentine flow, which affects the heat dissipation effect and the heat dissipation efficiency is low. In view of this, in-depth research on the above problems led to this case.

The invention discloses a fuel cell of a fuel cell automobile. The fuel cell comprises a fuel cell body, a water cooling structure is arranged on the fuel cell body, an air cooling structure is arranged on the water cooling structure, and a control structure is arranged on the water cooling structure. The fuel cell has the beneficial effects that the water cooling structure is arranged, two rectangular pipes are adopted in the water cooling structure to independently circulate cooling liquid, and the two rectangular pipes are spliced and flatly laid on the upper wall surface of the fuel cell, so that the contact area between the cooling liquid and the fuel cell is enlarged, the cooling liquid directly flows through the surface of the fuel cell, the heat dissipation effect is ensured, and the heat dissipation efficiency is improved; and the air cooling structure and the control structure are also arranged, and a plurality of cooling fans are controlled by using one fan speed regulation signal, so that accurate control on the temperature of the cooling liquid of the fuel cell is realized, the occupied quantity of hardware resources of the speed regulation signal is reduced, the cost is reduced, and the performance and the economic efficiency of the fuel cell are improved.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell for a fuel cell vehicle. Background technique [0002] In a fuel cell, the thermal management of the fuel cell is related to its energy conversion efficiency. The membrane electrode, the core component of the fuel cell stack, is sensitive to temperature. If the temperature is too high or too low, it will affect the performance of the stack. Only the temperature of the cooling liquid is conducive to the full performance of the fuel cell. The fuel cell thermal management system of a fuel cell vehicle mainly includes a power supply module, a radiator and a radiator fan speed control system. [0003] The power supply module provides the energy source for the entire fuel cell thermal management system. The radiator mainly includes a radiator and a radiator fan. The coolant flows through the radiator, and the radiator fan rotates to make the air flow through the radiato...
