Background
With the continuous development of modern social economy, scenic spots, forest zones, wetland parks, forest parks, natural protection areas and the like bring people leisure and entertainment, but potential safety hazards also bring people worries, and environmental protection also needs to be managed and controlled; on the basis, various intelligent network monitoring systems are applied, and all-weather and all-around 24-hour monitoring needs to be implemented. But the monitoring system cannot be powered off and will also provide night lighting when necessary. Due to the remote geographical locations of these places, the geographical environment is complex. The cost is very high when the commercial power AC220V or AC380V is laid, the application cost of solar energy is high, and the effect is not good; the power supply is seriously influenced in rainy days or haze days, and trees and the like are more in the areas, which are not favorable for sunlight irradiation. A methanol water reforming hydrogen fuel cell generator system is used for supplying power.
Hydrogen energy is a clean secondary energy source. In recent years, with the gradual maturity of the development of hydrogen energy application technology and the continuous increase of global pressure to cope with climate change, the development of the hydrogen energy industry is receiving attention in countries around the world, and developed countries such as the united states, germany and japan successively promote the development of the hydrogen energy industry to the high degree of the national energy strategy. Moreover, "hydrogen energy and fuel cell technology innovation" ranks the country in the initiative plan of energy technology revolution innovation, which indicates that the hydrogen energy production has been incorporated into the energy strategy of China. The hydrogen has the safety technical bottlenecks of 'preparation, storage, transportation' and the like; under the background, the system is produced as an industry for producing hydrogen at any time and generating power at any time, namely a power generation system combining methanol water reforming hydrogen production with a hydrogen fuel cell!
The principle of the hydrogen production combined hydrogen fuel cell generator by reforming methanol and water is that mixed solution of methanol and deionized water according to the mass ratio of about 60% is used as raw material, hydrogen-rich (C0, CO2 and H2) is generated after catalytic reforming, H2 with the purity of 99.99% is generated after purification, H2 with the normal temperature and low pressure is obtained after passing through a heat exchanger when the raw material enters, H2 enters a fuel cell to be converted into electric energy, and stable electric energy output is obtained after voltage stabilization treatment by DC-DC. The hydrogen-rich purified C0, CO2 and H2 are introduced from the other outlet of the purifier to a combustion chamber below the reforming chamber for combustion, and the generated energy provides proper temperature guarantee for the subsequent reforming chamber and the purifier. The pool off-gas is discharged after three-way catalytic treatment (small amount of CO2 and H2O steam).
According to the scheme, H2 generated by the hydrogen production part is in a normal-temperature low-pressure state, so that the danger caused by a hydrogen high-pressure steel cylinder is avoided; the raw material is a mixed solution of methanol and deionized water, so that the application danger of pure methanol is avoided; the scheme solves the safety technical bottlenecks of 'preparation, storage, transportation' and the like of hydrogen.
In addition, the methanol-water reforming hydrogen cell generator system is provided with a 40L (changeable) low-pressure (maximum 25psi) hydrogen buffer tank, and when the pressure of H2 is equal to 25psi, the hydrogen production machine automatically stops feeding liquid and is in a hot standby state; when the pressure is lower than 15ps, the hydrogen can be automatically fed into the liquid to produce hydrogen, and the hydrogen enters the fuel cell after passing through a pressure reducing valve (50-70 KPa). Thus, the whole system needs more electricity to generate more hydrogen, and a closed loop application is formed. Under rated power, the consumption rate of the system raw materials is lower than 0.85 kg/KWh; the total system produced only a small amount of CO2 and H2O in the cell bleed air. The system has the characteristics of energy conservation, environmental protection and the like;
in conclusion, the methanol-water reforming hydrogen fuel cell power generator system scheme is provided. The distributed energy source scheme not only solves the safety technical bottlenecks of 'preparation, storage, transportation' and the like of hydrogen, but also is energy-saving, environment-friendly and stable and is not influenced by severe conditions such as typhoon and the like.
