Specific embodiment：
Embodiment：As shown in Fig. 2,3, fuel cell moisture trap, including web plate 1, air water is provided with tank body 2 enter
Mouth 2a, web plate 1 are fixed with tank body 2, and valve body 3 is fixed on the bottom of tank body 2, and valve body centre bore 31, runner is formed on valve body 3
32, runner 32 is molded on valve body 3 and is mutually connected with valve body centre bore 31；
Float 4 is placed in tank body 2, and float sleeve hole 41 is formed on float 4,5 sleeve of valve element in valve body centre bore 31,
Guide rod 6 is fixed with valve element 5, in float sleeve hole 41, the top molding of guide rod 6 can be fixed with gear cap 7 to 6 sleeve of guide rod；
Valve body centre bore 31 is to form the stepped hole of step 311, and drain pipe 9 is spirally connected or is weldingly fixed on valve body centre bore
At 31, O-ring seal 8 is fastened between the upper surface of step 311 and drain pipe 9, and the outer wall of valve element 5 is connected with O-ring seal 8
Touch sealing to coordinate.
The web plate 1 is the plate with filtering holes.
The web plate 1 is to be fixed with filter screen structure on plate framework.
The float 4 is the float that hollow metal or plastic material are manufactured, and valve element 5 is conical, and valve element 5 is metal material
Manufacture and form.
Operation principle：During original state, the outer wall of valve element 5 is connected to sealing with O-ring seal 8 and is coordinated, now, in tank body 2
Water will not be flowed out by drain pipe 9.
The hydrogen produced in fuel cell and the pressure of the mixture of water less, the hydrogen produced in fuel cell and water
Mixture directly enter in tank body 2 from air water import 2a, web plate 1 filters out the impurity in the mixture of hydrogen and water, water and
After hydrogen is entered in tank body 2, water can produce buoyancy to float 4, work as tank in the top of tank body 2, water in the bottom of tank body 2, hydrogen
When water in body 2 reaches a certain amount, float 4 floats in water, and 4 pairs of gear caps 7 of float produce active force, so as to guide rod 6 is pulled
Valve element 5 is moved upwards, and outer wall and the O-ring seal 8 of valve element 5 are separated, and now water can flow into valve body centre bore from runner 32
After 31, then flow out from drain pipe 9, when pour off a certain amount of water after, the height of float 4 can be reduced, and valve element 5 can from gravity
In the presence of fall after rise downwards, when valve element 5 fall back to the outer wall of valve element 5 and O-ring seal 8 contact sealing coordinate when, then tank body 2
No longer outwards draining, in whole process, no hydrogen is discharged from tank body 2, and the hydrogen being so deposited in tank body 2 just can be again
Recycle, so as to improve the hydrogen utilization ratio of fuel cell, reduce the power supply cost of fuel cell.
When the water product in tank body 2 is to certain height, valve element 5 can be opened and allow 9 draining of drain pipe, row of the present utility model
Water is step mechanical type Auto-drainage, need not artificial timing manual drainage, without wanting Electronic Control draining.
In drainage procedure, valve element 5 remains sleeve in valve body centre bore 31, in order to ensure valve element 5 is remained
In valve body centre bore 31, the height of web plate 1 can be designed the correct position in tank body 2 to sleeve by us, it is ensured that gear cap 7 is encountered
During web plate 1, in valve body centre bore 31, simply the outer wall of valve element 5 is separated the still sleeve of valve element 5 with O-ring seal 8.
