Claim 3:
4. A method of operating an electrochemical system comprising:
providing a self-cleaning electrochemical cell comprising:
a plurality of electrodes disposed concentrically in a housing about a central axis of the housing;
a fluid channel defined between adjacent electrodes of the plurality of electrodes and extending parallel to the central axis; and
an electrical connector positioned at a distal end of at least one of the plurality of electrodes and electrically connected to the at least one of the plurality of electrodes,
the electrical connector being dimensioned to allow fluid flow through the fluid channel and provide an even current distribution to the at least one of the plurality of electrodes while maintaining a zone of reduced velocity having less than a predetermined length within the fluid channel downstream of the electrical connector, the zone of reduced velocity defined by a region in the fluid channel in which fluid flow velocity deviates from a mean fluid flow velocity in the channel by within 20%;

introducing electrolyte solution into the self-cleaning electrochemical cell at an average flow velocity through the fluid channel of about 2 m/s or greater;
applying a current across the plurality of electrodes at a voltage sufficient to generate a product compound from the electrolyte solution in the self-cleaning electrochemical cell; and
continuously operating the electrochemical system for a predetermined period of time.
