摘要：

Polyvinyl alcohol-containing silica gels doped with HClO4, H2SO4, or H3PO4 prepared by the sol-gel method exhibited high proton conductivities of 10(-5)-10(-2) S cm(-1) at room temperature. Totally solid state electric double-layer capacitors fabricated using the gels as an electrolyte and activated carbon powder, ACP, as a polarizable electrode showed large capacitances of 31-44 F/(gram of total ACP), which were comparable to those of the capacitors with liquid electrolytes.
