| 内容記述 | An anhydrous proton conductor, 10mol% In^3+ -doped SnP2O7 (Sn0.9In0.1P2O7) , was composed by 1,8-bis(triethoxysilyl)octane (TES-Oct) and 3-(trihydroxysilyl)-1-propanesulfonic acid ((THS)Pro-SO3H) and was characterized by structural and electrochemical analysis. The composite membrane with 90wt% Sn0.9In0.1P2O7 showed high proton conductivities of 0.04Scm^−1 or more between 150 and 200°C in unhumidified air. The packing of the Sn0.9In0.1P2O7 particles in the matrix was relatively uniform, with no formation of pinholes observed. Fuel cell tests verified that the open-circuit voltage was maintained at a constant value of ∼970mV regardless of the electrolyte thickness (60–200μm) , while the Ohmic resistance was decreased to 0.24Ωcm2 by reducing the electrolyte thickness to 60μm . The peak power densities achieved with unhumidified H2 and air were 109mWcm^−2 at 100°C , 149mWcm^−2 at 150°C , and 187mWcm^−2 at 200°C . Furthermore, fuel cell performance was improved by hot-pressing an intermediate layer consisting of Sn0.9In0.1P2O7 , Pt/C , TES-Oct, and (THS)Pro-SO3H between the electrolyte and cathode. | |||||
