Abstract: In recent years, considerable attention has been paid to the research and development of chemical sensors based on solid proton conductor electrolytes.Some proton conductors such as solid polymer membrane,zirconium phosphate, antimonic acid and so on, kept relatively high ionic conductivity even at room temperature. In this paper,this type proton conductor sensors for detecting combustible gases of H₂,CO and C₂H₄ at room temperature were fabricated and studied. We here described their structures, sensing mechanisms and performances. The effects of the temperature, humidity, catalytic electrode materials and preparation method of composite electrode on the sensor response were also discussed.These sensors will be extensively applied to the petrochemical industry,environmental protection and daily life.
