The dependence of EMF E of C|Ag|AgI|glass Ag2GeS3|D|C galvanic cells on temperature is studied in the range of 480-580 K (C are inert (graphite) electrodes; Ag, D are galvanic cell electrodes, D are equilibrium three-phase-of the Ag-Ge-Se system; AgI|glass Ag2GeS3 is a two-layer membrane with purely ionic (Ag+) conductivity). E(T) analytical equations are used for calculation of the values of thermo-dynamic functions for saturated solid solutions of structural modifications of the GeSe, GeSe2, Ag2GeSe3, Ag8GeSe6 phases in a Ag-Ge-Se system in the standard state.
