title = "Proton conducting silica particles: Relation between morphology and conductivity",
abstract = "The physical properties of sulfonic acid functionalized silica with different degrees of functionalization were studied. These samples were synthesized via a sol-gel route and dried under supercritical conditions to obtain highly porous and well-ordered structures. Morphology was studied via electron microscopy and nitrogen adsorption; impedance spectroscopy was used to measure the proton conductivity. The sample prepared with 25\%SO3H functionalization demonstrated high proton conductivity (30 mS/cm @ 90 °C and 100\% RH) and BET surface area (574 m2/g). This material had good properties for potential use as a fuel cell electrocatalyst support.",
