The invention relates to a method for optimizing the conductivity provided by the displacement of H+ protons and/or OH&#x2212; ions in a conductive membrane made of a material permitting the insertion of steam into said membrane, wherein said method comprises the step of inserting under pressure gaseous flow containing the steam into said membrane in order to force said steam into said membrane under a certain partial pressure so as to obtained the desired conductivity at a given temperature, said partial pressure being higher than or equal to 1 bar, a drop in the operational temperature being compensated by an increase in said partial pressure in order to obtain the same desired conductivity. The invention can be used in particularly interesting applications in the fields of high-temperature water electrolysis for producing hydrogen, of the manufacture of fuel cells using hydrogen fuel, and of hydrogen separation and purification.
