Background technology
Current global energy anxiety, oil price is surging, and the searching new forms of energy are the task of top priority as the substitute of fossil fuel.Fuel cell be considered to after waterpower, firepower and nuclear electric power generation the 4th generation generation technology, it is directly changed into electric energy by electrocatalytic reaction with the chemical energy of Oxidizing and Reducing Agents, is a kind of efficient, safety, cleaning, new-generation technology flexibly.Proton Exchange Membrane Fuel Cells wherein is because it has the efficient height, energy density is big, reaction temperature is low, noiselessness, remarkable advantage such as pollution-free are with a wide range of applications at aspects such as terrestrial power generation station, electric motor car and compact powers.Fuel battery inside mainly is made up of proton exchange membrane, electro chemical catalyst, diffusion layer and bipolar plates.When operation of fuel cells, it is inner, and following course of reaction takes place: reacting gas spreads in diffusion layer, when reacting gas arrives Catalytic Layer, is adsorbed by catalyst in Catalytic Layer and electrocatalytic reaction takes place; The proton that anode reaction generates is by being delivered to cathode side in the proton exchange membrane, electronics arrives negative electrode through external circuit, with oxygen molecule reaction bonded Cheng Shui, emits heat simultaneously.Electrode reaction is:
Anode (negative pole): H
2→ 2H
++ 2e
Negative electrode (positive pole): 1/2O
2+ 2H
++ 2e → H
2O
Cell reaction: H
2+ 1/2O
2→ H

Stand-by power supply mainly is in order to prevent that digital product from outage taking place or do not have standby power supply under the electric condition in long-time use.Conventional stand-by power supply is to be fuel with the lead-acid battery, but the environmental pollution of lead-acid battery own, and must change in 3 years, cost also will increase substantially.Society is all advocating environmental protection at present, seeks new forms of energy and replaces.So the new forms of energy fuel cell produces.The fuel cell principle is to be raw material with hydrogen and oxygen, directly produces electric energy by electrochemical reaction.Because the colorless and odorless of hydrogen fuel own, and has lower burning-point, so seem most important in the hydrogen safe handling.Supply with the safe hydrogen-feeding system of hydrogen that must have a cover and fuel cell to be complementary for ensureing fuel cell stand-by power supply hydric safe.
Hydrogen-feeding system on the market is simpler and easy at present, after changing the maintenance of hydrogen bottle and pipeline, the air in the pipeline is not purged, make hydrogen mix with air in the pipeline and cause potential safety hazard, use so present hydrogen supply bus-bar is not suitable for fuel cell stand-by power supply hydrogen supply system.
The nitrogen purging device that improves fuel battery service life in the patent No. 200720015229 is to install nitrogen purging device additional at fuel cell.Its structure is that nitrogen purging device is made up of nitrogen electromagnetically operated valve and the bottle that nitrogen is housed.The outlet of bottle is connected to the anode inlet of fuel cell through the nitrogen electromagnetically operated valve.Nitrogen purging device is discharged the air that infiltrates in the anode cavities before fuel cell start-up; When operation of fuel cells stops, hydrogen residual in the anode cavities is discharged.Effectively prevented hydrogen and air haptoreaction in the anode cavities, thus the useful life of having improved battery.This patent is mentioned the nitrogen purging and is only purged at the fuel cell pipeline, hydrogen supply bus-bar and homogeneous tube road is not carried out the nitrogen purging, is not suitable for the fuel cell stand-by power supply.
Self-generated nitrogen blowing and cleaning system at the patent No. 200710157420 protection fuel battery car engines, comprise fuel cell and air supply system thereof and hydrogen feed system, also comprise an air deoxidation jar in the self-generated nitrogen blowing and cleaning system, air deoxidation jar respectively with the hydrogen feed system, air supply system is connected with fuel cell, the beneficial effects of the utility model are: when fuel cell is, residual hydrogen in the hydrogen air chamber of fuel cell pack is by nitrogen replacement, prevented that fuel cell is corroded, improved the useful life of Proton Exchange Membrane Fuel Cells; Realized the automation of online preparation nitrogen and purging; Utilize fuel cell tail row hydrogen that the deoxidier of air deoxidation jar is regenerated, realized effective utilization of the energy, cost is low; Purging system simple in structure, easy to operate, the efficient height, the life-span is long, and applicability is wide, can be widely used in the Proton Exchange Membrane Fuel Cells automobile engine.This patent mention self-generated nitrogen blowing and cleaning system only at the residual hydrogen in the fuel cell pile hydrogen air chamber by nitrogen replacement, but can't purge hydrogen supply bus-bar pipeline, be not suitable for the fuel cell stand-by power supply.
The utility model content
Because the problems referred to above that prior art exists, the purpose of this utility model are to propose a kind of fuel cell stand-by power supply hydrogen supply bus-bar nitrogen purging system, it is a kind of safe and reliable hydrogen-feeding system that can be used for the fuel cell stand-by power supply.
For achieving the above object, the utility model is solved by the following technical programs:
A kind of fuel cell stand-by power supply hydrogen supply bus-bar nitrogen purging system, comprise the unidirectional valve that is connected with nitrogen cylinder, one manual exhaust-valve is connected with this unidirectional valve respectively with high-pressure pressure-reducing valve, one high pressure gauge and middle pressure table are respectively with after this high-pressure pressure-reducing valve is connected, be connected to low-pressure relief valve by this high-pressure pressure-reducing valve by pipeline again, a low-pressure meter is by successively being connected with snap joint with electromagnetically operated valve by pipeline behind this low-pressure relief valve.
