Modeling of Artificial Neural Networks for Hydrogen Production via Water Electrolysis

Abstract

Artificial neural networks have emerged as a promising tool for estimating hydrogen production process variables for reaction condition optimization. Here we aim to predict complex nonlinear systems that use of artificial neural networks for modeling hydrogen production via water electrolysis and to evaluate the common challenges that arise. 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. Furthermore, 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.

“…Artificial intelligence (AI), a subset of computer science combining advanced computing and statistics, is the ability of a machine to receive inputs and produce a behavior or reaction similar to that of an intelligent person. While humans have natural cognitive skills and learn through experience, artificial intelligence (AI) is based on data and algorithms [133]. Figure 25 shows the input parameters needed to produce hydrogen using artificial intelligence [134].…”
