This paper describes the operation of a bipolar alkaline electrolyser which is at least 60% efficient at evolving a hydrogen/oxygen mix. The electrolyser consists of 12 stainless steel (SS316L) electrodes of area 5400 cm2 in a sealed polypropylene unit. A pulsed potential waveform is applied to the electrodes in 0.12 M KOH electrolyte yielding on the order of 320 dm3/kWh of the hydrogen/oxygen mix...
