FIELD: physical chemistry.
SUBSTANCE: invention relates to the field of gas analysis, more precisely to the determination of the ionic transference number of solid electrolytes with proton conductivity. The essence of the invention is that the method for determining the ionic transference number in solid electrolytes with proton conductivity additionally contains a step at which the ionic transference number of a proton-conducting solid electrolyte is determined by the formula:
I2 (limiting)/I1(limiting), where: is the ionic transference number of a proton-conducting solid electrolyte at a known temperature and concentration of hydrogen in a gas mixture of hydrogen and an inert gas; I2 (limiting) – the limiting current flowing through a hydrogen-conducting electrochemical cell; I1 (limiting) – the limiting current flowing through an oxygen-conducting electrochemical cell.
EFFECT: expansion of the field of practical application of solid electrolytes with proton conductivity.
