摘　　要：采用中间相碳微球(Mesocarbon Microbeads,MCMB)和石墨(Graphite,G)作为原材料,并掺杂氯化铵,利用凝胶注模成型工艺,并通过1000℃埋碳烧结工艺,制备了管状乙醇燃料电池(TDEFC)电极支撑体。研究了不同氯化铵加入量对电极材料的孔隙率、抗压强度、抗折强度和电阻率等性能的影响。结果表明,采用掺杂氯化铵的方式可以制备孔隙分布均匀,孔隙率高的电极支撑体,从而有利于传质和催化效率的提高。Mesocarbon microbeads（MCMB）and graphite（G）were used as raw materials , and ammonium chloride was doped. Electrode substrate bodies of tubular direct ethanol fuel cell（TDEFC）were prepared by gel casting and got by being sintered at 1000℃ in carbon embedding condition. The effect on the properties of electrode material by mixing different contains of ammonium chloride were studied. The experimental results showed that the electrode substrate body of high porosity and uniform holes can be made by mixing ammonium chloride Which was in favor of mass transferring and improving catalytic efficiency.
