Modeling of Artificial Neural Networks for Hydrogen Production via Water Electrolysis

Abstract

Received: 11.09.2022 Accepted: 11.01.2023 Abstract: Artificial neural networks (ANN) have emerged as a promising tool for estimating hydrogen production process variables for reaction condition optimization. The objective of the study was to predict complex nonlinear systems using ANN for modeling hydrogen production by water electrolysis and to evaluate the common challenges encountered. To estimate the effect of different electrolyzer systems input parameters such as electrolyte material, electrolyte type, supplied power (voltage and current), temperature, and time on hydrogen production, a predictive model was developed. The percentage contributions of the input parameters to hydrogen production and the best network architecture to minimize computation time and maximize network accuracy were shown. The results show that the hydrogen production parameters from electrolysis and the predicted safety explosive limit are 7% of the average Root Mean Square Error (RMSE). Furthermore, the coefficient of determination value was found 0.93. This predicted value is very close to the observed values. The neural network algorithm developed in this study could be used to make critical decisions in the electrolysis process for parameters affecting hydrogen production.
