and step 3: and (3) completely disengaging the lock catch, and separating the equipment: the retractable pipe (17) is separated from the threaded pipe (24), the sliding plate (25) is pulled down, the clamping head (21) is separated from the fixing groove (19) at the bottom of the water receiving box (15), meanwhile, the fixing spring (20) in the limiting box (18) is pressed down, then the water receiving box (15) is pulled, and the water receiving box (15) is pulled out of the placing groove (2) through the rolling of the brake wheel (16);
and 4, step 4: complete detection, device recovery: and (3) adopting external special equipment to comprehensively analyze residual hydrogen, air and impurities in water mixed in the water box (15), thereby comprehensively testing the water balance of the hydrogen fuel cell and recovering the device after the test is finished.
2. The hydrogen fuel cell water balance test apparatus according to claim 1, characterized in that: the right side of the top of the working bottom box (1) is fixedly connected with a vertical plate (22).
3. A hydrogen fuel cell water balance testing device according to claim 2, characterized in that: one side of the vertical plate (22) is fixedly connected with a fuel cell body (23) through a connecting plate, and the bottom of the fuel cell body (23) is communicated with a threaded pipe (24).
4. The hydrogen fuel cell water balance testing apparatus according to claim 1, characterized in that: before detection, all professional functions of the machine are detected and qualified, and then the machine is started and heated to enter a standby working state.
