Abstract: The primary goal of this research is to predict the cyclic voltammetry and polarization curves of proton exchange membrane fuel cells (PEMFC) without conducting any experiments. For the first time ever, artificial neural network (ANN) is applied to introduce a framework for PEMFC that is composed of various catalyst layers. Carbon-based cathode materials, such as reduced graphene oxide, graphene oxide, graphene nanoplatelets, and carbon black and their hybrids, including various Pt catalyst content, are being investigated. Important properties of cathode materials, such as surface area, Pt percentage, and Pt nanoparticle size were investigated for the classification of various groups. Results showed that total cathode surface area and Pt content are suitable for more precise data classification and are selected as input variables (features), whereas electrochemically active surface area, cyclic voltammetry, and polarization curves are selected as output responses of ANN. In this framework, experimental data for various cathode materials is initially classified using support vector machines and then ANN models are applied to predict the cyclic voltammetry and polarization curves. Results indicate that data are well classified into four main groups, allowing an ANN to achieve the best prediction of curves with a mean square error of less than 0.3% and a relative error of 0.5%. Also, with the help of the polarization curve, the maximum production power vs different voltages can be evaluated. By applying this model, it will be possible to get the necessary electrochemical data for an unknown carbon-based cathode material of a PEMFC. Finally, ANN applications can be proposed as a useful tool for predicting the main cyclic voltammetry and polarization curves of fuel cells.
