A Nanocarbon Cage Could Make Hydrogen Fuel Cells Cheap Enough for Data Centers

Engineers at Washington University in St. Louis built a nanostructured carbon support that keeps platinum-cobalt fuel-cell catalyst particles from clumping even at 1,000°C, solving a long-standing activity-versus-durability trade-off. The catalyst kept 85% of its performance after 150,000 stress cycles, a step toward cheaper, longer-lasting hydrogen power.
