For electrochemical gas sensors, solid electrolytes play increasingly significant role in improving stability, life-span and other properties. One new but emerging solid electrolyte LaF3 is attractive because of its possible application at room temperature, in addition to other advantages and it has been investigated for measuring various types of gases. Since Pt/LaF3 sensitive interface is a core part of this kind of gas sensor, reasonable design and fabrication Pt working electrode micro-structure is a crucial approach to improve sensitivity, reduce response time of the sensor. In this paper, micro SO2 gas sensor based on Pt/LaF3 is proposed, and fluid dynamic simulation software Fluent was used to simulate gas flow around gas/Pt/LaF3 three-phase-boundary (TPB). Pt micro-structure at different micro-scales simulated by Fluent indicates that the scale influences gas-flow status around three-phase-boundary, and actually determines sensitivity and response property.
