Description
Technical Field
The invention relates to the field of fuel cells, in particular to a fuel cell water temperature control system and a control method thereof.
Background
The temperature distribution of the fuel cell stack has a significant impact on the safety and life of the fuel cell. To maintain a desired temperature inside the stack, the heat generated by the electrochemical reactions of the stack must be dissipated, requiring thermal management of the system. Generally, circulating cooling liquid flows among the single cells of the electric pile to achieve the purpose of heat dissipation and cooling, a heat management subsystem of the electric pile is structured as shown in fig. 1, and a water pump 7 drives the cooling liquid to circulate to dissipate heat in the electric pile 1. The cooling liquid circulation is divided into a large circulation flow path and a small circulation flow path, the large circulation flow path 4 flows through the heat dissipation part 3, and the heat dissipation part 3 rotates to force air convection to enhance heat dissipation; the flow rate of the small circulation flow path 6 is automatically adjusted and distributed by the thermostat 12 according to the water temperature without passing through the heat radiating member 3.
According to the operating temperature condition requirement of the fuel cell, the heat management is realized by controlling the temperature T of the cooling liquid in the stackinTemperature difference between pile entering and pile exitingc=(Tout-Tin) And (5) realizing. Wherein the temperature T of the cooling liquid in the reactor is controlledinThe normal operation of the stack 1, especially under low temperature conditions, can be ensured. At the same time, in order to realize the uniform temperature distribution in the galvanic pile 1, the temperature difference TcShould be as small as possible, but with a temperature difference ofcSmaller will result in greater coolant flow, thereby increasing parasitic power consumption and reducing system efficiency. On the other hand, temperature difference Δ TcLarger will result in a lower temperature to which the cooling liquid needs to be cooled, which will be limited by the ambient temperature and the performance of the heat-radiating member 3. Temperature difference TcIs a variable associated with the coolant flow.
When the temperature of the cooling liquid in the reactor does not meet the target temperature TinIn this case, the controller 9 adjusts the flow rate distribution relationship of the large and small circulation flow paths by controlling the opening degree of the thermostat 12 according to an algorithm. However, although the distribution proportion of the large and small circulating flow paths can be changed by adjusting the opening degree, the total flow of the two cooling liquids in the large and small circulating flow paths can be increased or decreased instantly due to the change of the flow resistance characteristics of the two paths of the large and small circulating flow paths when the opening degree is changed, so that the temperature difference of the system generates large fluctuation, and the problem of unstable temperature and temperature difference control occurs.
Therefore, it is desirable to provide a water temperature control system for a fuel cell and a control method thereof to solve the technical problem of unstable temperature and temperature difference control in the prior art.
