MATLAB/Simulink modelling and experimental results of a PEM electrolyzer powered by a solar panel

In this paper, the solar panels are used to power an electrolyzer to separate the water into hydrogen and oxygen gas. The electrical equivalent circuit for the proton exchange membrane electrolyzer was developed and implemented in MATLAB/Simulink along with the atmospheric hydrogen storage tank. The voltage (2 volt) and current (1 ampere) were supplied in a similar manner in order to compare the simulated and experimental results. The hydrogen amount is calculated to be 7.345 (ml/min A) from the model as well as the experimental set up. The experimental and simulation results were matched.
