Description

technical field [0001] The invention belongs to the technical field of fuel cell cooling circuit testing, and more particularly relates to a cooling circuit testing device for fuel cells used in automobiles. Background technique [0002] The on-board fuel cell must maintain a low conductivity of its cooling circuit during operation. Excessively high conductivity of the coolant will lead to a series of problems such as insulation failure of the vehicle and reduced efficiency of the fuel cell, resulting in the failure of the fuel cell and the vehicle to operate normally, and generate greater safety hazards. It is therefore crucial to test the ionization of fuel cell cooling circuits and treat them accordingly. At the same time, different from the heat dissipation module design requirements of ordinary fuel vehicles and electric vehicles, in order to ensure the stable and efficient operation of the fuel cell system, the on-board fuel cell heat dissipation module not only needs...
