The utility model proposes a kind of fuel cell generation atmospheric buffer devices.
Referring to Figure 1, the fuel cell generation atmospheric buffer device of the utility model embodiment includes passing through pipeline
Hydrogen storage surge tank 2, pile 3 and the exhaust solenoid valve 4 being sequentially connected, hydrogen in storing and buffer in hydrogen storage surge tank 2, then at
The input end 31 of pile 3 enters in pile and in conjunction with oxygen, and product is flowed to through outlet end and is vented after oxidation of hydrogen reduction reaction
Solenoid valve 4 is finally discharged in exhaust solenoid valve 4 outward.
In order to realize that the fuel cell generation atmospheric buffer device to the present embodiment carries out accurately Pressure monitoring, this
The input end of the hydrogen storage surge tank 2 of embodiment is connected with baroceptor 1, accurate to carry out to the Hydrogen Vapor Pressure entered in pipeline
Detection.
Preferably, the hydrogen storage surge tank 2 of the present embodiment is gasbag-type surge tank, and the material of hydrogen storage surge tank 2 is 304
Stainless steel and internal gas capacity are 3L.Since the prior art is usually diaphragm type surge tank for storing the tank body of gas, but
It is the reliability that the tank body got rusty easily therefore not can guarantee work, the present embodiment can guarantee that hydrogen gas buffering is relatively reliable
Durability is had more later.
Referring to Figure 1, the working principle of the fuel cell generation atmospheric buffer device of the present embodiment are as follows:
Hydrogen enters to inside baroceptor 1 from the quick connector of 1 bottom of baroceptor first, then using
Pipeline and be delivered in hydrogen storage surge tank 2, enter inside pile through piping from the anode of pile 3, and oxygen (or air)
It is then entered to inside pile 3 by cathode, the hydrogen in anode is broken down into two Hydrogen Protons and two electronics, two of them matter
Son becomes water in conjunction with oxygen, and proton then reaches cathode after external circuit forms electric current.In entire redox reaction
In the process, water is the emission of fuel cell displacement, enters to exhaust electricity by pipeline as the water body of form using steam in this way
It is discharged outward in magnet valve 4.
The hydrogen storage surge tank 2 of the present embodiment is the chamber as storage hydrogen, when the Hydrogen Vapor Pressure in pipeline increases, storage
Media collapse gas in hydrogen surge tank 2 be able to enter buffering pulser in, so that hydrogen enter to hydrogen storage surge tank 2 into
Row temporarily storage, and when the Hydrogen Vapor Pressure in pipeline reduces, the compressed gas in hydrogen storage surge tank 2 can then expand, and force hydrogen
Gas is back in conveyance conduit.Therefore it can be avoided the gas pressure change on 90% by the way that hydrogen storage surge tank 2 is arranged, so that defeated
The hydrogen sent can be close to laminar condition.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or
Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
