摘要

报道了基于固体聚合物电解质(SPE)的电化学氧传感器。氧传感器由三个多孔的C/Pt基气体扩散电极(GDE)组成，即工作电极、参比电极和计数电极。在测试气体没有外部加湿的情况下测试传感器的性能。为了实现Nafion膜的内部加湿，利用了氧还原原理和水的反扩散。传感器响应氧浓度从10 ppm到20%。

Performance of solid polymer electrolyte based oxygen sensor without external humidification

The Solid Polymer Electrolyte (SPE) based electrochemical oxygen sensor is reported in this paper. The oxygen sensor consists of three porous C/Pt based Gas Diffusion Electrodes (GDE) namely, working, reference and counter. The performance of the sensor is tested without external humidification of the test gases. In order to achieve internal humidification of the Nafion membrane, the oxygen reduction principle and back diffusion of water, is utilised. The sensor responds to oxygen concentrations from 10 ppm to 20%.
