Éliashberg theory is generalized to the electronphonon (EP) systems with the not constant density of electronic states. The phonon contribution to the anomalous electron Green’s function (GF) is considered. The generalized Éliashberg equations with the variable density of electronic states are resolved for the hydrogen sulphide SH3 phase under pressure. The dependence of both the real and the imaginary part of the order parameter on the frequency in the SH3 phase is obtained. The Tc = 177 K value in the hydrogen sulfide SH3 phase at the pressure P = 225 GPa has been defined.

The results of the solution of the Eliashberg equations for the Im-3m (170 GPa), Im-3m (200 GPa) and R3m (120 GPa) phases are presented. A peak value Tc = 241 K of the superconducting transition temperature has been predicted.
