“…[ 82,498 ] Roudbari et al. [ 508 ] reported that in half‐cell experiments, CCMs hot‐pressed at 110 °C resulted in the best performance. Again, these conflicting reports highlight that the performance of a particular MEA system is highly dependent on the materials of choice and operating conditions.…”

Polymer electrolyte fuel cells (PEFCs) are a promising replacement for the fossil fuel–dependent automotive and energy sectors. They have become increasingly commercialized in the last decade; however, significant limitations on durability and performance limit their commercial uptake. Catalyst layer (CL) design is commonly reported to impact device power density and durability; although, a consensus is rarely reached due to differences in testing conditions, experimental design, and types of data reported. This is further exacerbated by aspects of CL design such as catalyst support, proton conduction, catalyst, fabrication, and morphology, being significantly interdependent; hence, a wider appreciation is required in order to optimize performance, improve durability, and reduce costs. Here, the cutting‐edge research within the field of PEFCs is reviewed, investigating the effect of different manufacturing techniques, electrolyte distribution, support materials, surface chemistries, and total porosity on power density and durability. These are critically appraised from an applied perspective to inform the most relevant and promising pathways to make and test commercially viable cells. This holistic view of the competing aspects of CL design and preparation will facilitate the development of optimized CLs, especially the incorporation of novel catalyst support materials.

A bipolar membrane fuel cell (BPMFC) is a novel hydrogen/oxygen (H 2 /O 2 ) fuel cell consisting of two-layer membranes. The design of BPMFC is still in an early stage, and it requires profound research to explore its functions, working operations, and improve its performance. This review article systematically described the previous manipulations made in developing BPMFC in terms of process design and electrolyte materials. These two criteria are the most important in the design of BPMFC. Several modifications and manipulations were made, and the improvements observed over the years are also presented in this study in terms of electrochemical performance and properties. For instance, modifications and rearrangements of BPMFC components, new electrolyte materials, and different membrane layer integration techniques have been proposed. Different effects on BPMFC properties and performance were discovered when modifications were made. Some of the BPMFC managed to perform without any issues, whereas some encountered water management issues, lack of cell stability, and degradation of power output. To date, the optimal reported power density of the BPMFC was about 327 mW/cm 2 and it managed to operate successfully for 40 h without showing any signs of degradation. In this regard, the commercialization of BPMFC for fuel cell performance is recommended as it displays a high potential for improving electrochemical cell performance and ensuring high cell durability.

Cost reduction together with durability represent the primary challenges for cathode catalysts in polymer electrolyte membrane fuel cells (PEMFCs). The catalyst is often supported by carbon, which suffers from parasitic corrosion, particularly during start‐up and shut‐down operations. Transition metal carbides (TMCs) have attracted attention as a potential replacement for carbon supports because some of them have electronic structures likened to noble metals. Mo2C has shown promising activity as platinum support for the oxygen reduction reaction (ORR) but can suffer from oxidation and dissolution. Here, Mo2C supports are modified by surface tantalum (Ta) treatment using a variety of DC magnetron sputtering operating parameters. All supports modified by Ta showed improved corrosion resistance compared to the untreated support. Pt/Mo2C modified with Ta using a 500 V bias, 6 mTorr working pressure, and 2 min sputter time additionally showed improved kinetic current density and mass activity. Ta sputtering under these conditions were applied to the cathode side of a Pt/Mo2C membrane electrode assembly and showed significantly improved durability when subjected to an accelerated stress test. Ta‐modified Pt/Mo2C cathodes showed resistance to void formation and loss of electrochemical surface area. Ta magnetron sputtering can therefore be considered a viable surface treatment for improving the activity and stability of PEMFCs using Mo2C‐based supports.
