Abstract
An electrolyzer includes a plurality of vertically stacked electrolysis cells, with one or more electrolyte supply tubes adjacent to said plurality of electrolysis cells and having a plurality of fluid outlets configured to discharge an electrolyte solution from said one or more electrolyte supply tubes to each of said plurality of electrolysis cells. Each of the cells is provided with one or more drain assemblies, each drain assembly comprising a drain basin equipped, with a drain valve, such that some or all drain valves in a given set of assemblies are engaged by a. common control member configured and operable to actuate each of the drain valves between a closed and an open position. A plurality of electrodes is connectable to one or more electrical power sources and configured to pass electric current through the electrolyte solution introduced into said electrolysis cells via said outlets.
Electrolysis techniques and system implementations are disclosed comprising a plurality of reactors, each comprising electrolysis electrodes and configured to carry out a sequence of phases of an electrolysis process phase-shifted with respect to a sequence of phases of the electrolysis process carried out by at least another one of said plurality of reactors, one or more power sources for driving the electrolysis processes carried out by the plurality of reactors, and a control system configured to monitor changes in a power capacity of at least one of the one or more power sources and based thereon perform at least one of the following: (i) activate or deactivate one or more of the electrolysis processes carried out by the plurality of reactors, (ii) adjust a time duration of at least one of the phases of the electrolysis process; (iii) adjust the power supplied to at least one of the plurality of reactors from the one or more power sources; and/or (iv) adjust, remove or introduce, at least one phase of the electrolysis process.
