Green hydrogen is emerging as a promising alternative to fossil fuels as it has high mass-energy density, low refueling time, and zero emissions. The polymer electrolyte membrane or proton exchange membrane (PEM) fuel cell is an electrochemical device that converts the chemical energy of hydrogen directly into electrical energy. One of the major factors that obstruct the commercialization of green hydrogen technology is its high cost and limited durability. Hence, researchers around the world are extensively working towards improving the performance and reducing the cost of PEM fuel cells by improving the design and employing alternative materials. This paper focuses on providing a comprehensive overview of the performance parameters of the PEM fuel cell and all the recent advancements in the PEM fuel cell design aspects, such as novel flow field designs and their effectiveness, bipolar plate materials, coatings, and their effectiveness. This study also throws light on types of gas diffusion layers and sealing techniques, as well as materials employed in PEM fuel cell and stack development.
