Claim:
1. A method for determining the concentration of a gas in a two-component mixture at variable pressure comprising: measuring, by a gas sensor, a first characteristic parameter of conduction of said two-component mixture, the first parameter being representative of a high temperature T measuring, by the gas sensor, a second characteristic parameter of the diffusivity of said two-component mixture, the second parameter being representative of a cooling rate pt calculating, by a circuit of the gas sensor, a value of the concentration of said gas and the pressure of said two-component mixture from said parameters with the assistance of a mathematical function and characteristic coefficients of said sensor, outputting, by the gas sensor, the calculated value of the concentration of said gas; wherein said first and second parameters being measured in alternating mode at a given frequency (f), wherein the gas sensor outputs the calculated value, of the gas concentration to an electrolyzer to determine production of energy fuel based at least in part on the calculated value.
