ABSTRACT:
A fuel-air cell comprising an anode of readily corrodable metal such as aluminum or magnesium, a porous substantially non-corrosive cathode spaced from the anode and a caustic fluid electrolyte between and contacting the anode and cathode, said electrolyte is a mixture of a base having equivalent ionic conductance value of 180 or higher when tested in concentrations of 0.5 M and an acid having equivalent ionic conductance values of 100 or higher when tested in concentrations of 0.5 M and proton transfer reactance (PK1) values less than 1.0; whereby no corrosion of the anode occurs when, by varying the proportioning of the base and acid, the PH of the electrolyte is at or below 7, no appreciable corrosion of the anode occurs when the PH of the electrolyte is between 7 and 14; and minor corrosion of the anode occurs when the PH of the electrolyte is above 14.
