“…High proton conductivity and great mechanical characteristics may be achieved through in situ polymerization, although reaction conditions can be tricky to manage. Layer-by-layer assembly: using this method, polyelectrolyte layers are alternately deposited to create a membrane [ 42 , 43 ]. Multilayer membranes can be made with fine control over their composition and thickness via layer-by-layer assembly, although the process can be time-consuming and expensive.…”

Hydrogen energy is converted to electricity through fuel cells, aided by nanostructured materials. Fuel cell technology is a promising method for utilizing energy sources, ensuring sustainability, and protecting the environment. However, it still faces drawbacks such as high cost, operability, and durability issues. Nanomaterials can address these drawbacks by enhancing catalysts, electrodes, and fuel cell membranes, which play a crucial role in separating hydrogen into protons and electrons. Proton exchange membrane fuel cells (PEMFCs) have gained significant attention in scientific research. The primary objectives are to reduce greenhouse gas emissions, particularly in the automotive industry, and develop cost-effective methods and materials to enhance PEMFC efficiency. We provide a typical yet inclusive review of various types of proton-conducting membranes. In this review article, special focus is given to the distinctive nature of nanomaterial-filled proton-conducting membranes and their essential characteristics, including their structural, dielectric, proton transport, and thermal properties. We provide an overview of the various reported nanomaterials, such as metal oxide, carbon, and polymeric nanomaterials. Additionally, the synthesis methods in situ polymerization, solution casting, electrospinning, and layer-by-layer assembly for proton-conducting membrane preparation were analyzed. In conclusion, the way to implement the desired energy conversion application, such as a fuel cell, using a nanostructured proton-conducting membrane has been demonstrated.

To decarbonize the energy system, proton exchange membrane fuel cells (PEMFCs) have been proven to be the most viable device. Electrocatalysts used in the membrane electrode assembly (MEA) are vital parts facilitating the electrochemical reactions determining the overall performance of PEMFCs. The exposure of triple phase boundaries (TPBs) where these electrochemical reactions occurred is mostly dependent on electrode structure. Along with the promising aspects of PEMFCs, some issues regarding electrode durability, lower catalyst utilization, circuitous mass transport pathways in conventional electrodes are also raising concern. Unfortunately, half of the cost of a single cell is covered by electrocatalysts, which triggers the importance of its maximum utilization. The deployment of an innovative design in the electrode structure can eliminate those issues. Researchers have been trying to achieve higher power density and durability by modifying the architecture of the electrode introducing the different fabrication techniques. In this review, we attempted to illustrate current efforts to upgrade electrode architecture, highlighting the advanced design from macro-scale to nanoscale of electrode modification. The current status of the most common types of modified electrode structures, such as, template-based pattern, porous agglomerates, 3D ordered pattern, macropattern, micropattern, thin film, electrospinning, pore augmentation of the electrodes are discussed in details in this review. A brief description is also included to guide future R&D regarding the electrodes of PEMFCs. In addition, the functional mechanism of the modified electrode, fabrication routes, and comparative performance are also covered in detail. At the end, a summary of current research work is discussed with the aim of guiding future research prospects to upgrade electrodes for next generation PEMFC applications.
