摘    要:以硅酸钠或硅酸乙酯与甲醇、硫酸为原料,采用改性溶胶-凝胶法制备了溶胶-凝胶流动相.以SEM观察流动相的形貌,测定了其甲醇渗漏和电化学性能,并研究了流动相的制备温度及组分对成胶速率及甲醇渗漏的影响.结果表明,溶胶-凝胶流动相具有多孔结构,改变了甲醇的传质途径和传质机理,与相同浓度的甲醇和硫酸液相流动相相比,渗漏率下降了9...

关 键 词:直接甲醇燃料电池  溶胶-凝胶流动相  甲醇渗漏

Abstract:The sol-gel flux phase of direct methanol fuel cell was prepared by the modified sol-gel method by using Na2SiO3 or Si(OC2H5)4 and methanol,sulfuric acid.The sol-gel flux phase was characterized by SEM.The methanol permeability,electrochemical characteristics of the sol-gel flux phase,the influence of the preparing temperature and the composition of the sol-gel flux phase on the gel-formed rate and methanol permeability were investigated,which showed that the sol-gel flux phase had porous structure that cha...
Keywords:direct methanol fuel cell  sol-gel flux phase  methanol permeability
