    • Y02E60/521
    • PROBLEM TO BE SOLVED: To provide a mesoporous electrolyte in which both of a mesoporous structure and high acid group density can be kept and consequently high proton conductivity can be exhibited even under a non-humidified condition.SOLUTION: The mesoporous electrolyte includes: a mesoporous body which comprises silica and has meso pores; and organic sulfonate groups each modifying the inside surface of the meso pore and has 2.0-4.0 pieces/nmacid group density. The mesoporous electrolyte is obtained by subjecting a first precursor for forming a skeleton of the mesoporous body and a second precursor for modifying the inside surface of the meso pore by the organic sulfonate group to a copolycondensation reaction in the coexistence of a surfactant and a catalyst to obtain a complex in the meso pore of whose mesoporous body the surfactant is packed, performing skeleton strengthening treatment for strengthening the skeleton of the mesoporous body on the complex, and removing the surfactant from the complex.
    • 要解决的问题:为了提供即使在非加湿条件下也能够保持介孔结构和高酸基密度都能够显示出高质子传导性的介孔电解质。溶解性:介孔电解质包括:介孔 其包含二氧化硅并具有中孔; 和各自改性内孔的内表面的有机磺酸盐基团,具有2.0-4.0个/ nm酸组密度。 介孔电解质是通过将表面活性剂和催化剂共存的将介孔体的骨架的第一前体和用有机磺酸盐基团改性内孔的内表面进行共缩聚反应的第二前体 在表面活性剂填充的介孔体的介孔中获得复合物,进行骨架强化处理,以增强络合物上的介孔体的骨架,并从络合物中除去表面活性剂。
