This study introduces innovative advancements in catalyst and membrane technology to improve fuel cell performance and reduce costs. Platinum-group metal (PGM)-free iron-nitrogen-carbon (Fe-N-C) catalysts achieved a 0.85 W/cm2 power density, a 19.88% improvement over traditional PGM-free catalysts, with stable operation exceeding 1000 hours. Nanostructured carbon supports enhanced oxygen reduction reaction activity by 30.13% and current density by 25.02%. Additionally, a novel proton exchange membrane with superior ionic conductivity and durability increased fuel cell efficiency by 10.12% while significantly reducing hydrogen crossover rates. These advancements represent a breakthrough in developing cost-effective, high-performance fuel cell systems.
