Abstract
A three-electrode solid electrolyte hydrogen gas sensor is explored in this paper. The sensor utilized phosphotungstic acid as the electrolyte material and adopted platinum, nickel and tungsten as the three-electrode materials respectively. In real applications, platinum was used as the measuring electrode, nickel was used as the adjusting electrode and tungsten was used as the reference electrode. In order to compare the performance of the new sensor with that of the traditional two-electrode sensor, the hydrogen concentrations were adjusted so as to detect the output of the two-electrode sensor and the three-electrode sensor. The dynamic range between the measuring electrode and the reference electrode is about 0.65V and the highest detectable limit is 12% for the three-electrode solid hydrogen gas sensor. While the dynamic range is about 0.25V and and the highest detectable limit is 1% for the two-electrode solid electrolyte gas sensor. The results demonstrate that the three-electrode solid hydrogen gas sensor has a higher resolution and detectable limit than the two-electrode sensor. abstract environment.
