Description
Technical Field

Background
The hydrogen fuel cell is a power generation device which directly converts chemical energy generated by the reaction of hydrogen and oxygen into electric energy through electrochemical reaction, has the advantages of high power generation efficiency, small environmental pollution and the like, and is widely applied to the field of automobiles. The fuel cell generates a large amount of heat, and therefore a heat dissipation system composed of parts such as a radiator and a water pump is required to realize a temperature control function of the stack. Fuel cell engines require coolant ion deposition to be maintained within limits, which requires de-ionization devices integrated into the heat sink system to clean the antifreeze. The performance of the deionization tank of the fuel cell system is continuously reduced in the long-term operation process, so that the conductivity of the antifreeze cannot meet the requirement of the system, and the deionization tank needs to be replaced.
At present, the deionization tank for the fuel cell vehicle is not provided with a monitoring mechanism, so that the replacement period of the deionization tank can only be calculated or replaced regularly according to the running mileage, the performance of the deionization tank cannot be detected, and unnecessary replacement can be caused. Some existing fuel cell hydrogen systems rely on a separate conductivity meter to monitor the conductivity of the coolant in the hydrogen system piping to determine whether the deionization tank needs to be replaced. The deionization tank is judged to need replacement if the conductivity meter measures an increase in the conductivity of the system, which is less rigorous because the increase in conductivity within the system may be due to other reasons than a decrease in the performance of the deionization tank.
In view of the foregoing, it would be desirable to provide a deionization tank performance monitoring apparatus that overcomes the deficiencies of the prior art.
