Abstract

The invention provides a series-parallel fuel cell thermal management system with a double-ion filter and a method. The system comprises a circulation assembly, a deionization assembly and a switchingassembly, and a first backflow channel, a second backflow channel and a main circulation channel form the circulation assembly together; a first deionizer is installed in the first backflow channel through a first backflow bypass, a second deionizer is installed in the second backflow channel through a second backflow bypass, and a first backflow switching valve is installed between the first backflow channel and the first backflow bypass. A second backflow switching valve piece is installed between a second backflow channel and a second backflow bypass, the first backflow channel and the second backflow channel are made to operate independently or completely by controlling the first switching valve piece and the second switching valve piece, the first deionizer and the second backflow channel are made to operate independently or completely, and the operation mode is flexible and changeable; the real-time adjustment can be performed according to the conductivity test data obtained bythe first tester and the second tester, so that the management efficiency can be improved.

Description

technical field [0001] The invention relates to fuel cell technology, in particular to a thermal management system and method for a double-ion filter series-connected fuel cell. Background technique [0002] The conductivity of the fuel cell heat exchange fluid is a key issue related to the safety of the fuel cell system and the entire vehicle. During the operation of the fuel cell, a high voltage will be generated on the bipolar plate, but at the same time it is required that this high voltage will not pass through the bipolar plate The heat exchange fluid in the middle is transmitted to the entire cooling circulation channel, so the heat exchange fluid is required to be non-conductive. At present, the deionization filter of the commonly used fuel cell cooling system is designed as one, which is installed in parallel or in series with the radiator. When installed in series, the water resistance is large and the energy loss of the system is large, resulting in low system eff...
