“…Polymer electrolyte membrane fuel cells (PEMFC) are considered one of the most promising technologies among the various kinds of existing fuel cells due to their high power density and excellent power‐to‐weight ratio. Recently, several groups reported on the benefits of high‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFC) with an operating temperature of 120–200 °C . These high operating temperatures are made possible by a special type of membrane, which does not need to be swollen with water for good proton conduction as its Nafion TM counterpart in low temperature fuel cells .…”

High‐temperature polymer electrolyte membrane fuel cells are promising alternatives to low temperature fuel cells, owing to their higher operating temperatures, which allow for easier water management and enhanced catalytic activity. However, their performance suffers from low oxygen solubility in the electrolyte and phosphoric acid poisoning of catalytically active Pt sites. In this work, we developed new organic additives that provide π‐π stacking of the commercially applied carbon support materials as well as variable substitutable functionalities to interact with the Pt nanoparticles. Different electrochemical methods, such as cyclic voltammetry and linear sweep voltammetry, were performed to test the effect of these organic additives on the onset potential, limiting current, and the number of transferred electrons. It is observed that the limiting currents increase for the additive‐modified Pt/C samples, whereas the onset potential for significant oxygen reduction reaction activity remains unchanged. We conclude that enhanced oxygen solubility at the electrode/electrolyte interface is the reason for the observed behavior.

Summary The aim of this study is to analyze the exergy efficiency of a high‐temperature proton exchange membrane fuel cell. To do this purpose, meta‐heuristic technique has been used. First, the model of a membrane fuel cell is simulated and the polarization diagram shows a potent agreement with empirical data. Then, a new improved version of collective animal behavior algorithm is utilized for evaluating and optimizing the thermodynamic irreversibility, exergy efficiency, and work of the fuel cell. The algorithm uses opposition‐based learning and Lévy flight for improving the algorithm's premature convergence shortcoming. The result of this study shows that by comparison with standard collective animal behavior algorithm, genetic algorithm, and empirical results, the proposed algorithm has better achievements for both terms of optimal value finding and convergence strength.

“…Polymer electrolyte membrane fuel cell (PEMFC) is a potential power source for various applications due to its low operating temperature, high efficiency, high power density and good impermeability (González-Espasandín et al 2019;Rosli et al 2018). A significant component of the PEMFC is the bipolar plates which account for 80% of the total stack weight and 45% of stack cost (Antunes et al 2011;Mohd Radzuan et al 2016).…”

Bipolar plates significantly contribute to the development of the polymer electrolyte membrane (PEM) fuel cells technology due to their ability to produce high electrical conductivity based on the type of materials used. Mismatching of inappropriate materials and manufacture may lead to the inferior performance of PEM fuel cells. Hence, material development was determined crucial to balance the overall performance of PEM fuels including the mechanical properties and electrical conductivity of the materials. Studies on conductive polymer composites (CPCs) offered filler with orientation in terms of filler with aspect ratio and shape as an alternative method to enhance the overall performance of the bipolar plate. Filler orientations permit an excellent conductivity network formation while controlling the filler alignment based on required applications. This paper reviewed various studies of filler orientations including materials used and methods of manufacture of CPC materials for the effective development of bipolar plate. The technique to orientate the filler was highlight in terms of materials processing and its effects on the materials performance.
