METHOD FOR ACTIVATING SOLID ACID SALT, HIGH-CAPACITY CAPACITOR USING SAME, AND FUEL CELL

摘要

There is provided a method for activating a solid acid salt electrolyte capable of enhancing the proton conductivity of solid acid salts at a temperature at or below a point of phase transition to the super proton conducting phase, through humidity control, by taking advantage of this phenomenon. The method for activating a solid acid salt electrolyte, comprising the steps of preparing a solid acid salt electrolyte composed of cations and anions, and forcibly keeping the surface of the solid acid salt electrolyte at humidity in a range of 10 to 100 % at temperature in a range of 10 to 80°C, whereby proton conductivity in the solid acid salt electrolyte is improved.
