Technical field
The utility model relates to fuel cell field, is specially a kind of nitrogen purging device that improves fuel battery service life.
Background technology
Fuel cell is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) that chemical energy in fuel and the oxidant is converted into electric energy by the electrocatalytic reaction on the electrode.It is not subjected to the restriction of Carnot cycle, can efficiently chemical energy be converted into electric energy.Characteristics such as Proton Exchange Membrane Fuel Cells (Proton Exchange Membrane Fuel Cell, be called for short PEMFC) is owing to have cold-starting, and is simple in structure, easy to operate are the power sources that the most useful hope is applied to following electric automobile.
(particularly fuel cell electric vehicle) is not to move always in the fuel cell use, but exists frequent startup and docking process.Because in docking process, the air in the atmosphere can penetrate in the galvanic anode gradually, can be full of air in the anode cavities.Hydrogen and air mixed in anode one side in the start-up course can react, and to battery structure and certain corrosion and the destruction of material production, influence the life-span of fuel cell.When stopping once more, air enters anode cavities once more to be mixed with hydrogen and reacts.How the repeatable operation of going round and beginning again like this to the influence of life-span of battery greatly, therefore avoids contacting of hydrogen and air in the anode cavities, is fuel cell start-up and the parking key issue to the influence in life-span.At existing problem in the above-mentioned prior art, the device of a kind of novel raising fuel battery service life of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is the nitrogen purging device of a kind of novel raising fuel battery service life of research and design, the utility model is to purge by carry out nitrogen in fuel cell start-up and docking process, can react at anode one side hydrogen and air mixed in shutdown process thereby solve, to battery structure and certain corrosion and the destruction of material production, influence the problem of fuel battery service life.The nitrogen purging device of raising fuel battery service life described in the utility model is to install nitrogen purging device on fuel cell additional.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.
The concrete course of work of the present utility model is before fuel cell start-up, at first gives the energising of nitrogen electromagnetically operated valve, and nitrogen is sent to the anode cavities of fuel cell, and the air that infiltrates in the anode cavities is discharged, and the time is 3-20 second.The energising of working electromagnet valve is given in nitrogen electromagnetically operated valve outage then, and air (or oxygen) and hydrogen are sent to the negative electrode and the anode of fuel cell respectively, and fuel cell is started working.When operation of fuel cells finishes, working electromagnet valve outage, the energising of nitrogen electromagnetically operated valve is sent to the anode cavities of fuel cell to nitrogen, and the hydrogen in the anode cavities is discharged, and the time is 3-20 second.
The used nitrogen of the utility model also can use other inert gas.
The nitrogen purging device of raising fuel battery service life described in the utility model, be in fuel cell start-up and docking process, to carry out nitrogen to purge, elimination remains in hydrogen in the anode of fuel cell chamber and oxygen reaction to the influence of battery life, improves fuel battery service life.
The utlity model has the advantages such as useful life that novel structure, method are simple, economical and practical, prolong fuel cell, have positive social benefit and remarkable economic efficiency.
Description of drawings
The utility model has an accompanying drawing, wherein
Accompanying drawing 1 improves the nitrogen purging device structured flowchart of fuel battery service life
Among the figure: 1, fuel cell 2, working electromagnet valve 3, nitrogen electromagnetically operated valve 4, nitrogen bottle 5, hydrogen bottle
Embodiment
Specific embodiment of the utility model is to install nitrogen purging device additional on fuel cell 1 as shown in drawings.Nitrogen purging device is made up of nitrogen electromagnetically operated valve 3 and the bottle 4 that nitrogen is housed.The outlet of bottle 4 is connected to the anode inlet of fuel cell 1 through nitrogen electromagnetically operated valve 3.
Before fuel cell 1 starts, at first give the nitrogen electromagnetically operated valve 3 energisings, the nitrogen in the nitrogen bottle 4 is sent to the anode cavities of fuel cell 1, and the air in the anode cavities is discharged, and the time is 15 seconds.Nitrogen electromagnetically operated valve 3 outage gives the working electromagnet valve 2 energisings, and the hydrogen in air and the hydrogen bottle 5 is sent to the negative electrode and the anode of fuel cell 1 respectively, and fuel cell 1 is started working.When fuel cell 1 work stops, 2 outages of working electromagnet valve, 3 energisings of nitrogen electromagnetically operated valve, the nitrogen in the nitrogen bottle 4 is sent to the anode cavities of fuel cell 1, and the hydrogen in the anode cavities is discharged, and the time is 15 seconds.
By nitrogen purging device described in the utility model, can discharge before the fuel cell start-up and when stopping, air that infiltrates in the galvanic anode chamber and residual hydrogen, avoid effectively that hydrogen and air mixed react in the anode cavities, thereby effectively improve the start and stop life-span of fuel cell, that is to say the life-span of having improved fuel cell.
