Embodiment 1

[0026] A fuel cell humidifier test platform includes a dry air generating unit, an air heating unit, an air humidifying unit, a data acquisition system and an automatic control system. among them,

[0027] Dry air generating unit: including air compressor 1, air filter 3. Among them, the air compressor 1 can compress air to above 0.6 MPa; the air filter 3 can filter out moisture, impurities, and oil in the compressed air. The drain valve 17 provided under the air filter 3 can be manually opened to discharge moisture, dust, oil, etc. in the air filter.

[0028] The air heating unit uses finned heaters 6 with two or more. Different numbers of heaters are turned on at different flow rates to meet the requirement that the temperature can reach the corresponding set value at each flow rate. The fin heater 6 is wrapped with a heat insulating material to isolate the influence of the external environment temperature on the performance of the heater and improve the heating effect.

Abstract

The invention relates to a fuel cell humidifier test platform. The fuel cell humidifier test platform is characterized in that the fuel cell humidifier test platform comprises a dry air generating unit, an air heating unit, an air humidifying unit, a data acquisition system and an automatic control system, wherein the dry air generating unit is used for generating dry compressed air having a certain pressure and needed by test; the air heating unit is used for heating the dry compressed air to a test setting temperature; the air humidifying unit is used for generating steam, humidifying the dry compressed air and simulating a humidifying side gas or a humidified side gas of a humidifier to be tested; and the data acquisition system and the automatic control system are used for setting testconditions and collecting test data. The fuel cell humidifier test platform can control the temperature, the relative humidity, the pressure and the mass flow of air before the air flows through thehumidifier and test the pressure drop, the temperature change and the relative humidity change before and after the air flows through the humidifier in order to determine water heat and mass transferin the humidifier, so data bases are provided for the design, optimization and application of the humidifier.

Description

Technical field [0001] The invention relates to the field of fuel cell humidifiers, in particular to a fuel cell humidifier test platform. Background technique [0002] A fuel cell is a battery that converts fuel chemical energy into electrical energy, which is essentially different from a primary battery and a secondary battery. The primary battery needs active material reaction to supply power. Once the reaction is over, the battery is scrapped. Although the secondary battery can be used repeatedly, it cannot be charged. For the fuel cell, as long as it meets the continuous supply of fuel, it can be discharged continuously without being restricted by time and space, and is simple to operate and save manpower. Because of its high energy conversion rate, low noise and close to zero exhaust pollution, it has become a popular research direction. [0003] The working principle of Proton Exchange Membrane Fuel Cell (PEMFC) is the same as that of other fuel cells. It is a kind of powe...
