Solid state protonics is a new reseach field attracting much current attention. One of the most urgent subjects in this field is to create a novel proton conductor, from the viewpoint of developing new energy and energy conservation technologies, including photovoltaic, hydrogen storage and fuel cell technologies. In this work, we report on a proton-conductive organic-inorganic hybrid system, which is a coordination polymer. Such a metal-dimer system with multi-redox property has a large potentiality for the creation of new-functional and high-performance materials in metal-complex solids^1.We have developed several kinds of proton conductors, which are 1-D, 2-D as shown in Figure, and 3-D coordination polymers. From the complex-plane impedance measurements, all the coordination polymers were found to be highly proton-conductive at room temperature. Among them, H_2dtoaCu exhibits highest proton conduction (〜 10^<-2> S cm^<-1>). This value is comparable to that of Nafion, which is famous for a solid electrolyte of fuel cell. The mechanism of proton conduction is discussed in detail. New highly proton-conductive coordination materials and highly-concentrated hydrogen-storage nano-materials are also discussed.

固体质子学是当前备受关注的一个新的研究领域。从开发新能源和节能技术（包括光伏、储氢和燃料电池技术）的角度来看，该领域最紧迫的课题之一是创造新型质子导体。在这项工作中，我们报告了质子导电的有机-无机杂化系统，这是一个配位聚合物。这种具有多重氧化还原性质的金属-二聚体体系对于在金属络合物固体中创造新型功能和高性能材料具有巨大的潜力^[1]。我们已经开发了几种质子导体，如图所示的一维、二维和三维配位聚合物。从复平面阻抗测量，所有的配位聚合物被发现是高度质子导电在室温下。其中，H_2dtoaCu的质子传导率最高，为100 μ <-2>S·cm ~（-1<-1>）。该值与以燃料电池固体电解质而闻名的Nafion相当。详细讨论了质子传导的机理。并对新型高质子导电配位材料和高浓度储氢纳米材料进行了讨论。
