The main goal of this work is to verify if use of quasi-solid-state electrolyte can improve the performance of the electrochemical gas sensor for detecting the toxic gases. In order to achieve this goal, the quasi-solid-state organic-inorganic hybrid electrolytes with high ionic conductivity are synthesized by using reactive silica particles, tetra(ethylene glycol) diacrylate and sulfuric acid, and their electrochemical properties are investigated. The quasi solid-state electrolytes are then applied to electrochemical gas sensors, and the sensor responses are measured. The results obtained in the gas sensors with quasi solid-state electrolyte are compared with response obtained in conventional electrochemical gas sensors employing liquid electrolyte.
