Special Issue Information

Dear Colleagues,

Fuel cells are energy-converting devices that generate electricity via an electrochemical process using fuel and oxygen. Water and heat are the by-product of the reaction, hence making this energy-generating medium environmentally friendly. There are several types of fuel cells, and each of them differs from one another based on the type of membrane used and their operating temperature. Proton-exchange membrane fuel cells are one of the types of fuel cells that are gaining much interest because of their suitability for the automotive industry; in particular, they have a number of portable and stationary applications. Cost remains a major setback for this technology, impeding their commercialization.

This Special Issue, therefore, invites novel contributions in terms of numerical and experimental research activities championed to accelerate the commercialization of proton-exchange membrane fuel cells.

Research activities from material characterization of various components in the cell to experimental and numerical investigation aimed at improving the overall performance of the cell are highly welcomed in this Special Issue. Research and review articles are therefore invited in this Special Issue to meet the growing demand for the development of novel, sustainable and environmentally friendly—but less expensive—proton-exchange membrane fuel cells for automotive and stationary applications.

A proton exchange membrane fuel cell (PEMFC) is a more environmentally friendly alternative to deliver electric power in various applications, including in the transportation industry. As PEMFC performance characteristics are inherently nonlinear and involved, the prediction of the performance in a given application for different operating conditions is important in order to optimize the efficiency of the system. Thus, modelling using artificial neural networks (ANNs) to predict its performance can significantly improve the capabilities of handling the multi-variable nonlinear performance of the PEMFC. However, further investigation is needed to develop a dynamic model using ANNs to predict the transient behavior of a PEMFC. This paper predicts the dynamic electrical and thermal performance of a PEMFC stack under various operating conditions. The input variables of the PEMFC stack for the analysis consist of the cathode inlet temperature, anode inlet pressure, anode and cathode inlet flow rates, and stack current. The performances of the ANN models using three different learning algorithms are determined based on the stack voltage and temperature, which have been shown to be consistently predicted by most of these models. Almost all models with varying hidden neurons have coefficients of determination of 0.9 or higher and mean squared errors of less than 5. Thus, the results show promise for dynamic modelling approaches using ANNs for the development of optimal operation of a PEMFC in various system applications. Full article

Commercialization of proton exchange membrane fuel cells can only materials provided its performance is closely related to existing technologies useful in commercial application. Other critical parameters like the utilization of cheaper materials should be taken into account during the manufacturing of the cell. A key component in the cell that has direct correlation to the cell performance is the flow plate. The weight coupled with cost of the cell revolves around the flow plate used in the manufacturing of the cell. This study explores materials ideal for the manufacturing of fuel cells in order to improve the overall cell performance. The investigation highlights the critical impact of varying materials used in the manufacturing of flow plates for PEM fuel cells. Stainless steel (SS), aluminium (Al) and copper (Cu) were the materials considered. The flow plate designs considered were serpentine and open pore cellular foam channel. Machine learning using python for the validation of the results with Linear regression, Ridge regression and Polynomial regression algorithm was carried out. The performance of both flow field channels was compared using different bipolar plate materials. The results show that metal foam flow channels overall performance was better than serpentine flow channels with all the various bipolar plate material used and Al material outperformed Cu and SS material. There is a direct correlation in terms of the outcome of the study and literature based on the data generated experimentally. It can however be concluded that molecules of hydrogen are stable on aluminium plates compared to copper and stainless steel. Full article
