Abstract
Phosphosilicate glasses and thin films with different nanopores were prepared via sol-gel method, and those proton conductions are presented. These glasses have large amount of –OH groups, and proton conductivity increases by absorption of water molecules. Proton transfer occurs with accompanying water molecules, and proton dynamics are affected significantly by a confinement effect of nanopores. Pore structures, especially pore size, are therefore one crucial aspect for fast proton conduction. In the case for thin films, direction of pores can be easily controlled, and proton conductivity changes by the ordered pores. Proton conduction of glasses prepared via conventional melt-quenched method is also shown as comparison.
