Problems solved by technology
If the conductivity meter measures an increase in system conductivity, it is determined that the deionization tank needs to be replaced. This method is not rigorous, because the increase in conductivity in the system may be caused by other reasons, not because of the decline in the performance of the deionization tank.

Description
technical field [0001] The invention relates to a monitoring device, in particular to a deionization tank performance monitoring device. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy generated by the reaction of hydrogen and oxygen into electrical energy through an electrochemical reaction. It has the advantages of high power generation efficiency and low environmental pollution, so it is widely used in the automotive field. The heat generated by the fuel cell is huge, so it is necessary to realize the temperature control function of the stack through a heat dissipation system composed of components such as radiators and water pumps. Fuel cell engines require that the ionization of the coolant be maintained within a certain range, which requires the integrated deionization device in the heat dissipation system to clean the antifreeze. During the long-term operation of the fuel cell system, the perf...
