Researchers have developed a core-shell catalyst that protects platinum nanoparticles from degradation in hydrogen fuel cells. By using an Fe-N-C protective layer, the catalyst maintains over 97% of its activity after 30,000 stress cycles, significantly outperforming standard commercial options. This advancement addresses the high cost and short lifespan of fuel cell components. Improving catalyst stability is a key step toward making hydrogen power more viable for clean transportation and industrial power applications.
