High temperature potentiometric hydrogen sensor based on BaCe0.6Zr0.3Y0.1O3-α-ZnO

One of the alternatives to carbon-based fuels is hydrogen. Hydrogen isotopes are expected to be used as a fuel for nuclear fusion power. The measurement of these isotopes in high-temperature environments (>350 °C) is of great interest. Electrochemical sensors based on solid-state electrolytes hav...

Electrochemical sensors based on solid-state electrolytes have been proved to be able to operate at elevated temperatures, with great physical and chemical stabilities.
