Research On Application Of Backup Power System Based On Methanol Hydrogen Fuel Cell

The fuel cell is increasingly used in substations,communication base stations and other fields as a standby power system,which has the advantages such as zero pollution byproducts,low operating noise,high efficiency,long power supply,and so on.As the main fuel of fuel cell,the disadvantages of hydrogen such as storage,transportation of high pressure pure hydrogen,which has become one of the “bottleneck” for the commercial development of fuel cell technology.How to obtain the hydrogen quickly and safely is becoming an urgent problem for the applications of fuel cell.Based on the above problems,this paper has carried out the research on the modeling and design application of methanol-hydrogen fuel cell backup power system.In this paper,the research status of hydrogen energy,fuel cell technology,backup power system is introduced.Through analyzing the different fuel cells and their characteristics,we can know the advantages of methanol-hydrogen fuel cell are different from others.Based on the analysis of the operating characteristics of methanol-hydrogen fuel cells,the models of methanol reforming to make hydrogen and proton exchange membrane fuel cell are established,and verified by the simulation and experiment.The overall structure of standby power supply system for methanol-hydrogen fuel cell is designed,the working modes are analyzed in detail,and the control strategy of the system is given.On the basis of previous research,a applied to the actual base station with the methanol-hydrogen fuel cell standby power supply system is tested.The testing results show that the design of system is correct and reasonable.Compared with traditional base station backup power system,it solves the problems such as environment and noise pollution,which has an important guiding significance for the future development of methanol-hydrogen fuel cell backup power system applied in the communication base stations and other venues.
