With the development of society and the progress of science and technology, the application range of new energy is gradually expanded and traditional fossil fuels are gradually replaced, and fuel cells in the new energy are widely applied to the fields of fixed power generation, transportation, portable power supplies and the like due to the advantages of high efficiency, low noise, low starting temperature, zero pollution and the like.
The cooling system in the fuel cell requires the electrical conductivity to be in a very low range to ensure proper operation of the fuel cell. However, during the operation of the fuel cell, ions are inevitably generated due to the abrasion of metal components and the corrosion of piping and the like by gas and liquid, and particularly, a large amount of ions are precipitated from the radiator. And in the operation of the fuel cell, it is required that a high voltage generated at the bipolar plate is not transferred to the entire cooling circulation flow channel through the coolant in the middle of the bipolar plate, and thus, the coolant is required to be nonconductive. The deionizer is used for removing ions in the cooling liquid, so that the cooling liquid keeps low conductivity within a safe range.
As the fuel cell operates, the deionizer has a gradually diminishing ability to remove ions, and needs to be replaced in time when it fails to meet the conductivity requirement. Existing testing techniques typically employ the addition of some ion-containing material (e.g., salt) to the cooling fluid and record the conductivity of the cooling fluid at that time and record the process time as the conductivity drops below 5 mus. However, in the galvanic pile with different powers, the flow rate and pressure of the cooling liquid are different, the temperature is slightly different, and ions are continuously precipitated when the galvanic pile is operated. The existing testing technology can not accurately simulate the process and the quantity of cooling liquid ion separation, and has great difference with the process of generating ions by a fuel cell, so that the performance and the service life of the deionizer can not be accurately tested.
