A galvanic cell generates hydrogen and has a metal or plastic housing and having one or more apertures for an interchange of gases. The cell has a hydrogen storage electrode and a gas electrode in an alkaline electrolytic solution. The storage electrode is a nickel alloy powder or such powder embedded in an electrically-conducting matrix. A galvanic cell generates hydrogen and has a metal or plastic housing and having one or more apertures for an interchange of gases. The cell has a hydrogen storage electrode and a gas electrode in an alkaline electrolytic solution. The storage electrode is a nickel alloy powder or such powder embedded in an electrically-conducting matrix. The gas electrode is a porous, twin-layer electrode of polytetrafluroethylene powder mixed reactively with Raney metal powder from the eighth column of the periodic table. The storage electrode incorporates alloys which are lower down the periodic table than hydrogen or nickel. Prior to installation within the cell, the nickel alloy is activated by electro-chemical means, subjecting it repeatedly to at least plus 200 mV. An independent claim is included for a manufacturing process in which the storage electrode is heated to between 400 and 850 [deg]C and homogenised. |
