Abstract
The experimental work is based on the PV solar powered membraneless KOH alkaline sono-electrolyzer using indirect continuous sonication under real meteorological conditions. The site of the study (36.9 N, 7.77 E) is located at the extreme North-East of Algeria, covering the semester ranging from March to September. A validated semi-empirical model for the dynamic assessment of
the global incident solar radiation is adopted, in association with a fundamental model based on the electrical analogy of the electrolytic cell. The experimental setup and measurements coupled to the preliminary numerical model led to a fraction of electrode coverage of 37% with a maximum recovery of 13%and10%inohmicandcellvoltages, respectively. The characterization of the sonication system through the calorimetric technique demonstrated an acoustic efficiency of 13.7%.
