摘要: Abstract A system for hydrogen production via water electrolysis using solar energy has been designed and is presented in this paper. Investigations were related to the experimental measurements modeling of 60 W electrolyzer 100 W PV module separately and, subsequently, as coupled system. The goal paper was increase efficiency while simplifying system's design. Electrolyzer features operating temperature, voltage electric current investigated detail. In mathematical model electrolyzer, important parameters determined based on UI characteristics, which included electrolyte ohmic resistance, electrode overvoltage, active surface. Experimentation allowed authors improve electrolyzer. It clear explains phenomena variable temperature real conditions due new steady state higher profile developing process continues. This statement presents main contribution work. supported with experiments explained detail through With 77.06% systems are be roughly compatible each other. emphasis describe both systems. All models programmed Simulink/MATLAB software.
