An electrolytic cell, a method for manufacturing the cell, and a method of operating same. The electrolytic cell has at least two bipolar plates, at least one fluid inflow and outflow, as well as at least one laminated core arranged between the at least two bipolar plates. The laminated core is constructed from laminations which are stacked one on top of the other. At least two laminations have recesses which are designed to extend through the entire thickness of the respective lamination. The at least two laminations are arranged one on top of the other in such a way that recesses in adjacent laminations overlap partially, but not completely, as a result of which ducts, which are continuous in the direction of the plane of the lamination, are formed.

Power is supplied to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. An AC transformer is used, and triggering of the coil is performed via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associate device, thus preventing losses when power is supplied and especially when the power is discharged.

Method for supplying and discharging power to and from a resistive-inductive load, and rectifier used therein

A magnet wheel and a stator winding which are necessary for an excitation device are included in a synchronous machine. Energy is transferred to the magnet wheel through inductivity, preferably, energy to a super-conductive coil, by the excitation device. Protection against the magnetic field produced by the current in the winding head is provided in the form of a specific system which is used to reduce the corruptions of the interfering fields of stator and rotor winding.
