Attorney, Agent or FirmInternational ClassesC25C 007/08C25C 001/16 C25C 007/00 C25D 017/00 AbstractAn electrolytic cell (10) comprises a plurality of cathodes (12) interspersed among a plurality of anodes (16). The plurality of cathodes and plurality of anodes form a plurality of electrodes spaced and suspended in parallel fashion in an electrolyte solution (35). The electrolytic cell further comprises a plurality of scrapers (14). Each scraper of the plurality of scrapers is placed between each of the plurality of electrodes in parallel fashion and the scraper moves a minimal distance relative to the plurality of electrodes. |
