Abstract

The possible use of thin H_xWO₃ films as a reference electrode in a Nernst type hydrogen sensor is investigated. Thin WO₃ films have been prepared by reactive dc magnetron sputtering from a tungsten target in an oxygen atmosphere. The structure and homogeneity of the films are investigated by x - ray diffraction and ion scattering spectroscopy. After intercalation of hydrogen in the WO₃ films by cathodic reaction in H₂SO₄, we studied the influence on the open circuit potential of the hydrogen concentration in the electrolyte and the hydrogen mole fraction in H_xWO₃.
