As the demand for alternative power sources grows, fuel cells (FCs) are emerging as promising options for zero-emission power. However, the development of highly active and durable catalysts is crucial to improve their efficiency. Platinum is one of the most popular catalysts for proton exchange membrane FCs, but its high cost and scarcity make it necessary to increase its utilization and activity. One way to achieve this is by increasing the active surface area of platinum through the preparation of nanoparticles and dispersing them on support surfaces. However, this approach presents a challenge as the supports must remain stable under the working electrochemical potentials. Thus, finding more electrochemically stable supports is a pressing issue today.
