Water-gas separation device of battery stack test platform

Abstract

The invention discloses a water-gas separation device of a battery stack test platform. The devicecomprises a water-gas separation mechanism, a gas discharge mechanism and a first cooling mechanism, and is characterized in that the water-gas separation mechanism comprises a water-gas separation tank and a heat dissipation coil pipe, the water-gas separation tank is internally provided with an isolation cavity, the heat dissipation coil pipe is arranged in the isolation cavity, two ends of the heat dissipation coil pipe respectively protrude out of the upper end and the lower end of the isolation cavity, the heat dissipation coil pipe is connected with an air outlet of the battery stack through a main loop pipeline, the first cooling mechanism is communicated with the isolation cavity to form a first circulation loop, cooling water circularly flowing in the first circulation loop enters the isolation cavity and exchanges heat with a water-gas mixture in the heat dissipation coil pipe to achieve gas-water separation, and the gas discharging mechanism is connected to the top of the water-gas separation tank and used for discharging separated waste gas. The water-gas separation device is simple in structural design, low in manufacturing cost, low in running cost of water-gas separation, smooth in water drainage and free of water blockage.

Description

technical field [0001] The invention relates to the technical field of fuel cell stack testing, in particular to a water-gas separation device suitable for a hydrogen fuel cell stack testing platform. Background technique [0002] The fuel cell stack is a power generation device composed of multiple single cells in series. The fuel cell stack converts the chemical energy of the fuel into electrical energy. Therefore, it is not limited by the Carnot cycle effect, has high power generation efficiency, and has Due to the advantages of low emission and low noise, fuel cells are widely used in the automotive industry, energy power generation, shipbuilding industry, aerospace, household power supply and other industries. [0003] After the fuel cell stack is assembled, it needs to test its various performances to ensure that the performance of the fuel cell stack meets the factory standard. At the same time, the performance test of the fuel cell stack is also the key to its develo...

AI Technical Summary

Problems solved by technology

[0004] At present, the water and gas separators configured on the fuel cell stack testing platform are basically purchased imported water and gas separators, and the price of imported water and gas separators is very high

Moreover, most of the water-gas separators currently used on the market are mechanical devices inside, with precise design and high cost, and have very high requirements for air flow and pressure, so the scope of use is narrow, and there are also problems of poor drainage and water blocking. question
