Background technique

Deionizers are used in the cooling system of hydrogen fuel cell engines and are mainly used to remove free conductive ions in the coolant. During the operation of the stack system, the bipolar plates will generate high voltage, which requires that the generated high voltage will not be transmitted to the entire cooling circulation channel through the coolant in the middle of the bipolar plates, so the coolant is required to have a low conductivity. state.

In the design and later application of deionizers, how to maximize the exchange capacity of the deionizer within the limited space of the vehicle while controlling the flow resistance of the product within a reasonable design range has become a major issue in industry competition.
