Description
Technical field
The utility model belongs to hydrogen fuel cell device technical field, specifically hydrogen fuel cell hydrogen gas recovering device.
Background technique
Hydrogen fuel cell be by hydrogen electrode supply hydrogen, while to oxygen electrode supply oxygen.Hydrogen, oxygen are on the electrode
Catalyst action under, water is generated by electrolyte.At this moment there is extra electronics on hydrogen electrode and negatively charged, on oxygen electrode
It is positively charged due to lacking electronics.After connecting circuit, this reaction process for being similar to burning can be carried out continuously.
Fuel is supplied to cathode when work（Hydrogen）, oxidant is supplied to anode（Oxygen）.Catalyst of the hydrogen on cathode
Cation H+ and electronics e- are resolved under effect.Hydrogen ion enters in electrolyte, and then externally circuit shifts to anode to electronics.With
The load of electricity just connects in external circuit.On anode, oxygen absorbs the electronics arrived on anode with the hydrogen ion in electrolyte
Form water.
Hydrogen fuel cell needs constantly to drain at work, what existing water was usually directly discharged by pipeline, and
During water is discharged, the hydrogen discharge that do not react completely is had in drainage channel, the utilization rate of hydrogen is caused to decline.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of hydrogen fuel cell hydrogen gas recovering device, this kind of hydrogen fuel
Battery hydrogen gas recovering device can prevent hydrogen to be discharged in draining, to increase the utilization rate of hydrogen, and structure letter
It is single.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：Hydrogen fuel cell hydrogen
Gas recovering device, including anode, cathode, hydrogen inlet, oxygen intake and discharge outlet, the discharge outlet bending are connected with downwards
Side has the cavity of opening, is hinged with rotation axis on the cavity of the overthe openings, the rotation axis end is provided with
Floating ball, is provided with fork arm in the rotation axis, and the fork arm is equipped with the sealing-plug for blocking the opening, the floating ball from
The sealing-plug blocks the opening when so hanging, and the height of the floating ball is higher than the height of the opening.This kind of hydrogen recycling
Device floating ball sealing-plug that hangs naturally when liquid level is lower than opening blocks the opening, prevents hydrogen from running out of from opening, when
Liquid level pushes floating ball to rise when rising to float position, and sealing-plug is separated with opening, and water is discharged from opening, can using the structure
It effectively prevent hydrogen to run out of from opening, to increase the utilization rate of hydrogen, and structure is simple.
In above-mentioned technical proposal, it is preferred that the cavity upper end is provided with safety overflow valve.It can be prevented using the structure
Fuel cell internal pressure is excessively high, effectively prevent safety accident.
The utility model compared with prior art, has the advantages that：This kind of hydrogen gas recovering device is lower than in liquid level
The floating ball sealing-plug that hangs naturally blocks the opening when opening, prevents hydrogen from running out of from opening, when liquid level rises to floating ball
Push floating ball to rise when position, sealing-plug separates with opening, water from opening discharge, using the structure can effectively prevent hydrogen from
Opening is run out of, to increase the utilization rate of hydrogen, and structure is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing：Referring to Fig. 1, hydrogen fuel
Battery hydrogen gas recovering device, including anode 1, cathode 2, hydrogen inlet 3, oxygen intake 4 and discharge outlet 5, the discharge outlet 5 are curved
It folds down and is connected with the cavity 7 that side has opening 6, be hinged with rotation axis 8 on the cavity 7 of 6 top of opening, it is described
8 end of rotation axis is provided with floating ball 9, and fork arm 10 is provided in the rotation axis 8, and the fork arm 10 is equipped with described for blocking
Opening 6 sealing-plug 11, the floating ball 9 when hanging naturally the sealing-plug 11 block it is described be open 6, the height of the floating ball 9
Higher than the height of the opening 6.This kind of hydrogen gas recovering device floating ball when liquid level is lower than opening sealing-plug that hangs naturally is stifled
Opening is stated in residence, prevents hydrogen from running out of from opening, pushes floating ball to rise when liquid level rises to float position, sealing-plug and opening
Separation, water are discharged from opening, hydrogen can be effectively prevent to run out of from opening using the structure, thus increase the utilization rate of hydrogen,
And structure is simple.
7 upper end of cavity is provided with safety overflow valve 12.Fuel cell internal pressure can be prevented excessively high using the structure, had
Effect prevents safety accident.
