Hydrogen energy monitoring

Program Overview
As the "blood" coolant of the fuel cell cooling system, its "trace element" content is crucial to the normal operation of the system. During the circulation process of the coolant, the "impurities" will continue to increase, resulting in a continuous increase in its conductivity, a decrease in the resistance value, and a decrease in the insulation performance of the system. In order to ensure safety, the electrical insulation performance of the fuel cell cooling system, especially the high voltage electrical insulation performance, is very important, which requires reducing the electrical conductivity of the fuel cell cooling fluid. Therefore, the coolant is required to have high heat dissipation, low corrosion rate, high seal material compatibility and ultra-low conductivity. The industry usually requires the conductivity of the coolant to be less than 5μS/cm, which requires real-time detection of the conductivity of the fuel cell engine coolant.
