摘　　要：以吐温80为分散剂,分别以丙烯酰胺和N,N’-亚甲基双丙烯酰胺为单体和交联剂,制备中间相碳微球/石墨(MCMB/G)浆料,采用凝胶注模工艺,制得直接醇类燃料电池管状阴极支撑体素坯,经液态干燥、滚动干燥和埋石墨粉烧结等过程处理制得其样品。所制备的直接醇类燃料电池管状阴极支撑体物理性能为:孔隙率42.7%,电阻率0.0276Ω.cm,抗折强度6.23 MPa,抗压强度16.29 MPa,具有收缩率低、变形量小、石墨化度高、电导率高、力学性能好等特点。Using Tween 80 as dispersant,acrylamide as monomer and bisacrylamide as crosslinking,the mesocarbon microbead/graphite（MCMB/G） slurry was prepared by adopting gelcasting to gain the tubular cathode substrates biscuit of Direct alcohol fuel cell,those samples were perpared by the process of liquid drying,rolling drying,buried graphite sintered and so on.The tubular cathode substrates have the characteristics of low shrinkage rate,small deformation,high degree of graphitization,high conductivity,good mechanics properties and so on.The physical properties of tubular cathode substrates for direct alcohol fuel cell are as follows： porosity is 42.7%,resistivity is 0.0276Ω·cm,flexural strength is 6.23 MPa,compressive strength is 16.29 MPa.
