【摘要】采用三电极结构 ,Nafion 117膜为中间固态电解质 ,研制一种新颖的全固态控制电位电解型SO2 气体传感器。研究表明 :其响应时间、底电流、结构性能等均优于Au Nafion膜作为中间电解质的半固态控制电位电解型SO2 气体传感器与全液态SO2 气体传感器。在SO2 气体间断监测上具有较好的应用前景更多还原

【Abstract】 The paper deals with the derelopment of a new full solid Amperometic SO 2 gas sensors by taking trielectrode structure, nafion 117 as a mid solid electrolyte. The study shows that its response to time, base current and behaviour are all superior to those of semi solid and full liquid ones of Au Nafion with longer service life and better prospects in irregular inspection of SO 2 gas.更多还原
