基于质子导体的燃料电池型气体传感器

某些质子导体如固体高分子膜、磷酸氢锆和锑酸等在室温下对化学传感器有足够的离子电导，研究和开发了在室温下可以检测H₂、CO、C₂H₄等可燃气体的质子导体传感器，研究其结构、敏感机理和特性，并研究温度、湿度、催化电极材料和复合电极制备技术对传感器性能的影响.

GAS SENSOR OF FUEL CELL TYPE BASED ON PROTON CONDUCTOR

In recent years, considerable attention has been paid to t he research and development of chemical sensors based on solid proton conductor el ectrolytes.Some proton conductors such as solid polymer membrane,zirconium phos phate, antimonic acid and so on, kept relatively high ionic conductivity even at room temperature. In this paper,this type proton conductor sensors for detecti ng combustible gases of H_2,CO and C_2H_4 at room temperature were fabricated and studied. We here described their structures, sensing mechanisms and perfor mances. 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 indust ry,environmental protection and daily life.
