Investigations of Pulse and Continuous WaterrnElectrolysis by Taguchi Method

摘要

This study applied the Taguchi method to investigate the effects ofrntwo sets of designed factors on water electrolysis. The first set is primarilyrnused to determine the pulse current effect on water electrolysis. The secondrnset is to determine the effects of electrolysis time, current density,rnelectrolyte concentration and electrode space on continuous waterrnelectrolysis. Results of pulse water electrolysis show that the effect of pulserncurrent on water electrolysis is small, which is verified and confirmed byrnquantitative experiments. In both studies, the current density and electrolyternconcentration play the most important role on water electrolysis among therndesigned factors. They together contribute about 70% on water electrolysis.rnResults of continuous water electrolysis show that, as expected, the smallerrnthe current density and electrode space, and the larger the electrolyternconcentration is, the smaller the applied voltage is. Nevertheless, therndecrement of applied voltage is small as the electrolyte concentration isrnhigher than 5%.
