Comparison of experimental results with simulation of a PEM Electrolyzer powered by a horizontal wind turbine

摘要

In this paper, one small wind turbine is used to power an Electrolyzer unit to separate the water into hydrogen and oxygen gases. Two volt voltage and 1 amp current were supplied to the Electrolyzer in order to produce hydrogen through the fuel cell unit. 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 hydrogen production was measured during the tests and evaluated running the simulation in order to compare the simulated and experimental results. The hydrogen amount is measured to be 6.99 (ml/min A) from the experimental set up as well as the model to be 7.24(ml/min A). The DC-DC buck converter was added to the Horizon kit to regulate the voltage to be 2 volts. The experimental and simulation results featured an error of 3.6 %.
