Green Hydrogen Generation from the PEM Electrolyzer Powered by Solar Panel

Abstract

Over the last decade, industries and the international scientific community have been interested in producing hydrogen by water electrolysis. Renewable energy sources (wind, solar, and hydraulic) are promising solutions to minimize the environmental impact in the pathways for producing hydrogen. This paper proposes a mathematical model of a PEM electrolyzer powered by the solar panel to know the system behaviour. A MATLAB/simulation platform is used to simulate the model. It can be seen that the amount of electrolytic hydrogen generated varies linearly with the input current. At the same time, the efficiency of the system varies nonlinearly with input electrical power. The hydrogen production rate under varying temperature and pressure conditions has also been observed. An example has been taken and hydrogen production rate from theoretical calculation is found which agree with simulation results.
