The device is composed of two electrolytic cells. The left one is hydrogen elimination chamber (anode chamber). A constant potential is applied on the anode surface of the specimen. The hydrogen atoms diffused from the cathode surface are oxidized on the anode surface.The right cell is the hydrogen charging chamber (cathode chamber). During hydrogen charging, the cathode current is applied on the cathode surface.
