  • Modular electrochemical cell
    Patent number: 7335284
    Abstract: A modular electrochemical cell having two interchangeable assemblies each with a support structure defining a cylindrical recess and having a fitting for connecting a pipe to the assembly. A disc-shaped electrode is arranged inside each recess and the assemblies are arranged relative to each other so that their respective electrodes face each other. A modular insert is inserted between the assemblies to define an open space between the electrodes and to distribute fluid to a plurality of openings spaced from each other along an edge of this open space. Securing members secure together the two assemblies and the modular insert, and passages in the support structures convey fluid between the fittings and the modular insert.
