摘　　要：针对直接甲醇燃料电池(DMFC)催化剂活性低和甲醇渗透等问题,利用Pd的催化阻醇性能,以油胺表面活性剂为添加剂,还原Pd络合物,合成基于Pd的催化阻醇纳米材料,并涂覆到质子交换膜上,与阴极、阳极构成四合一复合膜电极组件(MEA)。与常规三合一MEA相比,复合MEA的质子电导率更高,甲醇渗透率降低了20%,电池性能得到提升。在30℃、60℃和80℃温度下,复合MEA制备的电池性能均高于常规MEA制备的,最高输出功率密度达152.32 mW/cm^(2)。In order to solve the problems of low catalytic activity and methanol permeability in direct methanol fuel cell(DMFC),Pd-based catalytic methanol barrier nanomaterials were synthesized by using the catalytic methanol barrier performance of Pd and reducing Pd complex with oleylamine surfactant as additive.A four-in-one composite membrane electrode assembly(MEA)with cathode and anode was fabricated by coating Pd nanomaterials on proton exchange membrane.Compared with conventional three-in-one MEA,the composite MEA had higher proton conductivity,the methanol permeability was reduced by 20%,thus the performance of the cell was improved.Under the temperature of 30℃,60℃and 80℃,the performance of cell prepared by the composite MEA was all higher than that prepared by conventional MEA,the maximum output power density reached 152.32 mW/cm^(2).
