the sixth stop valve (18) is used for controlling the connection and disconnection of the air supply pipeline between the air supply pipeline and the test fuel cell stack (system); the hydrogenation gun (19) is used for being connected with a hydrogenation port of a test vehicle so as to supply hydrogen to the test vehicle; when the device needs to supply hydrogen for a fuel cell automobile in a test, firstly, all the stop valves are ensured to be in a closed state, and then the first high-pressure hydrogen cylinder group (1) and the second high-pressure hydrogen cylinder group (2) filled with hydrogen are well connected with a gas supply pipeline; adjusting the working position of the reversing valve (7) according to the test requirement, and switching on the first mass flowmeter (8) (the test hydrogen supply pressure of the fuel cell automobile is generally below 4MPa and above 2 MPa); opening the first, second and fifth cut-off valves (3, 4, 17) while the third, fourth and sixth cut-off valves (14, 16, 18) continue to remain closed; opening valves of the first high-pressure hydrogen cylinder group (1) and the second high-pressure hydrogen cylinder group (2), and operating the hydrogenation gun (19) to exhaust air in the whole air supply pipeline; the hydrogenation gun (19) is connected with an automobile hydrogenation port; when the test is started, the hydrogenation gun (19) is opened to supply hydrogen for the automobile, and the flow information of the first mass flow meter (8) is recorded; after the test is finished, the hydrogenation gun (19) is closed, valves of the first high-pressure hydrogen cylinder group (1) and the second high-pressure hydrogen cylinder group (2) are closed, and the third stop valve (14) and the fourth stop valve (16) are opened to discharge hydrogen for a hydrogen supply pipeline and the hydrogenation gun (19); after the pressure relief is finished, closing the third stop valve (14), the fourth stop valve (16) and the fifth stop valve (17); disconnecting the gas supply pipeline between the first high-pressure hydrogen cylinder group (1) and the second high-pressure hydrogen cylinder group (2) and the gas cylinder switching and pressure regulating combined valve (5); the hydrogen supply device and the high-pressure hydrogen cylinder are removed, and the test is finished.
