Abstract
In the conversion of chemical energy into electric energy by the electrochemical reaction of a gaseous anodic reactant and a gaseous cathodic reactant through the medium of a heteropoly acid solid electrolyte, the life of the solid electrolyte is notably increased by passing each reactant through pools of a saturated aqueous solution of a specific salt bordering on closed empty spaces thereby allowing the reactants to acquire prescribed humidities prior to the contact thereof with the anode and cathode.
Claims1
A method for the conversion of chemical energy into electric energy by the continuous electrochemical reaction of an anodic reactant held in contact with an anode and remaining in a gaseous state at room temperature with a cathodic reactant held in contact with a cathode and remaining in a gaseous state at room temperature through the medium of a heteropoly acid solid electrolyte, which method is characterized by incorporating a step of passing said anodic reactant and cathodic reactant through pools of a saturated aqueous solution of a selected salt each bordering on a closed empty space and retained within a fixed temperature range and releasing said anodic reactant and cathodic reactant into successive closed empty spaces thereby enabling said reactants to acquire fixed relative humidities prior to the contact thereof with the anode and cathode.
