Abstract
The performance characteristics of a bipolar membrane electrolyser for KOH production designed, fabricated and operated at CECRI are discussed. The bipolar elements have been bonded by a novel technique invented at CECRI. Activated anodes and cathodes developed by CECRI and imported Nafion membranes are being used in this electrolyser. Nafion 961, Nafion 90209 are the different membranes tried. The catholyte concentration, KCl depletion and membrane type on current efficiency, cell voltage and water transport across the membrane are reported
