Titanium phosphorus oxide (TiP) and composites with titania (Ti/TiP) were prepared by a sol-gel method. Tip membranes coated on slide glasses showed high electrical conductivities based on surface resistivity measurements at 150℃. The conductivities increased drastically with the partial pressure of water in the range of 0 to 10 kPa, and showed an electrical conductivity as high as 10^<-2> S/cm at a vapor pressure of 2.5 kPa (relative humidity of 0.5 RH%). Two types of membrane-electrode assemblies (MEAs) : a pore-filling-type and a thin-film-type, were constructed using Anodisc【○!R】, a porous alumina membrane (pore size : 100 nm ; thickness 60 μm). The proton transport number through the pore-filling type MEA was found to be approximately one. The two types of MEAs were successfully used in fuel cell experiments in a hydrogen/ air system. The performance of the thin-film-type MEA was superior to the pore-filling-type MEA. Moreover, two types of thin-film type of MEAs were prepared using electrically-conductive porous carbon substrates. MEA-2, which were prepared after fabricating an intermediate layer consisting of mixtures of carbon particles and polyimide, showed a better i-v performance than MEA-1, which were prepared directly on porous carbon substrate.

采用溶胶-凝胶法制备了钛磷氧化物（TiP）及其复合材料（Ti/TiP）。基于150℃下的表面电阻率测量，涂覆在载玻片上的尖端膜显示出高电导率。在0 ~ 10 kPa的范围内，随着水分压的增加，电导率急剧增加，在<-2>蒸气压为2.5kPa（相对湿度为0.5RH %）时，电导率高达10 μ S/cm。使用Anodisc[○！R]，多孔氧化铝膜（孔径：100 nm ;厚度60 μm）。通过孔隙填充型MEA的质子运输数被发现是约1。这两种类型的MEA成功地用于燃料电池实验中的氢/空气系统。薄膜型MEA的性能上级孔填充型MEA。此外，两种类型的薄膜类型的MEA制备使用导电多孔碳基板。MEA-2是在碳颗粒和聚酰亚胺的混合物制成中间层后制备的，其表现出比直接在多孔碳基底上制备的MEA-1更好的i-v性能。
