摘要
The operating principles and characteristics of solid-state electrochemical hydrogen sensors built with proton-conducting solid electrolytes were discussed. Selection criteria for the electrolyte, reference electrode, and working electrode were reported. It was shown that in hydrogen-air mixtures, the steady-state response of a platinum electrode to changes in hydrogen concentration is determined by hydrogen ionization and oxygen ionization, and depends on the oxidation state of the platinum surface. The major characteristics of the potentiometric sensors were reported.
