100W直接甲醇燃料电池堆的设计

北京理工大学珠海学院2020届本科生毕业设计Design of 100W direct methanol fuel cell systemAbstractDirect Methanol Fuel Cell (DMFC)is a kind of proton exchange membrane Fuel Cell,which uses methanol as fuel.Compared with other fuel cells,it has the advantages of simplersystem structure,high energy density and convenient fuel storage,etc.It is especially suitablefor power supply of portable devices and has a broad application prospect in the field of microand small mobile power supply.Most conventional proton exchange membrane fuel cells useNafion membrane as the proton exchange membrane,but since Nafion membrane is notsuitable for the fuel cells using methanol as fuel,this design will use sulfonated polyimideproton exchange membrane as the proton exchange membrane of the battery.This designrefers to the literature related to the design of hydrogen-empty proton exchange membranefuel cell system,and designs a 100W direct methanol fuel cell reactor based on the sulfonatedpolyimide proton exchange membrane.Keywords:Methanol:Sulfonated polyimide proton exchange membrane:Fuel cell,:Batterystack
