Phosphosilicate Gels as a Solid State Proton Conductor at Medium Temperature and Low Humidity

open access: yesPhosphosilicate Gels as a Solid State Proton Conductor at Medium Temperature and Low Humidity
Phosphosilicate (P2O5-SiO2) gels with a P/Si molar ratio of 1.0 heat-treated at 150°C were found to retain a high conductivity of 1.5×10-2S·cm-1 even after holding at a temperature of 130°C at a relative humidity of 0.7% for about 400 min. On the other hand, the conductivity of the porous silica gels impregnated with 5M H3PO4 largely decreased from 1 ...
