FIELD: chemistry.
SUBSTANCE: sensitive element of a hydrogen sensor in gas mixtures is made in the form of a hard electrolyte tablet, with the comparison electrode made of silver being baked onto one surface and the working electrode being baked onto the opposite surface; the working electrode is made of a mixture of an oxide compound with high electron conductivity and silver with its content in the mixture of 8-15 wt %.
EFFECT: increase of accuracy of hydrogen measurement, stability of readings, increase of the temperature range of measurements and simplification of technology of the sensitive element production.
