以3-环氧丙氧丙基三甲氧基硅烷、正硅酸乙酯和磷酸为原料，制备了以玻璃纸为载体的质子导电无机-有机膜。使用40μ m厚的玻璃纸获得了厚度为80μm的混合膜。通过玻璃纸支撑杂化膜，能够形成具有小厚度和高机械强度的膜。使用由玻璃纸支撑的膜的测试电池的开路电压为0.75V，并且在130°C的电池温度和7%的相对湿度下，在300 mAcm-2的电流密度下获得约85 mWcm-2的功率密度。
Proton conductive inorganic–organic membranes supported by glass paper were prepared from 3-glycidoxypropyltrimethoxysilane, tetraethoxysilane and orthophosphoric acid. Hybrid membranes with a thickness of 80μm were obtained by using 40μm-thick glass papers. Support of the hybrid membrane by the glass paper enables the formation of the membrane with small thickness and high mechanical strength. The open circuit voltage of the test cell using the membrane supported by the glass paper was 0.75V and a power density of about 85mWcm−2was obtained with current density of 300mAcm−2at cell temperature of 130°C and 7% relative humidity.
