1. In a magnetohydrodynamic thermal-to-electrical energy conversion apparatus, a duct provided with a working fluid containing conductive gas products, at least a pair of anode and cathode electrodes disposed in the duct adjacent to the fluid and cooling means provided in the duct for cooling the anode and cathode electrodes to temperatures lower than about 1,500* C., the improvement being characterized in that said cathode electrode is made of an alloy consisting of a refractory metal having a melting point of about 300* C. higher than the surface temperature of the cathode and an adhesive metal having a melting point higher than the surface temperature of the cathode, a specific resistance smaller than about 10 X 10 6 Omega -cm at 20* C. and a thermal conductivity larger than about 0.16 cal. cm. 1sec 1deg 1 at 20* C., each of the metals having a sufficiently small mutual solubility, whereby the grains of said refractory metal are dispersed in a matrix of said adhesive metal.
