Abstract: Title: INTERNAL ELECTRICAL CONNECTIONS FOR CONCENTRIC TUBULAR ELECTROCHEMICAL CELLS (57) : Self-cleaning electrochemical cells, systems including self-cleaning elec- 1240 trochemical cells, and methods of operating self-cleaning electrochemical cells are dis- closed. The self- cleaning electrochemical cell can include a plurality of concentric elec- trodes disposed in a housing, a fluid channel defined between the concentric electrodes, and an electrical connector positioned at a distal end of a concentric electrode and electri- cally connected to the electrode. The electrical connectors may be configured to provide a substantially even current distribution to the concentric electrode and minimize a zone of reduced velocity occurring downstream from the electrical connector. The electrical connector may be configured to cause a temperature of an electrolyte solution to increase by less than about 0.5 °C while transmitting at least 100 W of power.
