Abstract in another language
Dynamic measurement methods are an appropriate tool for the realization of highly selective solidelectrolyte based gas sensors. Three dynamic methods are used in this work to investigate Pt|YSZbased sensors. The polarization of Pt|YSZ sensors with alternating voltage pulses and the measurement of the resulting self-discharge behavior leads to a very sensitive and selective NOx sensor. By using the dynamic cyclic voltammetry method, it is possible to detect H₂ and O₂ simultaneously and selectively in low concentration ranges under certain measuring conditions. The third method, the coulometric measurement method, is used for the determination of the amount of exchanged oxygen during polarization of the system Pt|YSZ. For 400 °C, an uptake of O₂ of the polarized Pt|YSZ sensor was found.
