An electrochemical cell has an inner, titanium-rod electrode ( 1 ) mounted coaxially within an outer, titanium-tube electrode ( 2 ) with a porous, ceramic tube ( 3 ) mounted coaxially between them to define coaxial, annular passageways ( 4,5 ) for liquid flow in separate streams lengthwise of the cell between respective pairs of inlet/outlet ports ( 6, 6; 7, 7 ). A cup-shape fitting ( 8 ) having a stepped-down internal diameter is clamped onto the rod electrode ( 1 ) at each end of the cell, with the tubular electrode ( 2 ) at that end held tightly sealed in the mouth ( 14 ) of the fitting ( 8 ). Each end of the ceramic tube ( 3 ) projects into the larger-diameter cavity-part ( 10 ) of the fitting ( 8 ) at that end and has a radial flange ( 17 ) that provides a sliding seal within this cavity-part ( 10 ) for keeping the inlet/outlet ports ( 6,7 ) for the respective liquid streams at that end, divided off from one another as well as allowing the ceramic tube ( 3 ) limited freedom for longitudinal sliding relative to the electrodes ( 1, 2 ).
