Influence of temperature and humidity on titanium electrodes intended for an above normative conditions sensors

A series of test titanium electrodes, intended for a new generation of hydrogen and hydrogen compounds sensors was prepared. This new generation of hydrogen sensors is expected to operate in above normative conditions. In order to investigate the influence of temperature and moisture on titanium electrodes a series of experiments was conducted. Test samples were exposed to elevated levels of temperature (up to 165°C) and moisture (relative humidity up to 80%). These test allowed to measure resistivity as a function of temperature and to determine the long-term stability of electrical parameters of electrodes. Results of this studies will be used in fabrication of reliable electrodes for a new generation of hydrogen sensors.
