Patent ID: 8147661

Claim:
A unit for the electrolysis of water comprising: a first lateral housing wall provided with an inlet for water from a reservoir; a second lateral housing wall provided with an outlet for a product of the electrolysis; a plurality of stacked conductive plates separated from each other by a non conductive sealing ring and wherein the first lateral housing wall and the second lateral housing wall are separated from the following conductive plate by a further non conductive sealing ring as well: at least one of the stacked conductive plates functioning as an anode; and a plurality of other conductive plates functioning as a cathode, wherein the number of cathodes double the number of anodes; further conductive plates of the plurality of stacked conductive plates, not functioning as anode or cathode, being arranged such that between the at least one anode and each of the cathodes at least one further conductive plate of the further conductive plates is positioned; and between each outermost cathode and the first lateral housing wall and the second lateral housing wall at least one additional conductive plate is positioned.
