Description
Xueru Zhao and a large team use pressurised gas in 2026 to rearrange the surface of platinum-nickel fuel cell catalysts for heavy-duty vehicles. Gas pressure during heat treatment decides which metal enriches the surface: low pressure favours platinum, high pressure brings nickel outward. Their high-pressure nitriding route also forms nickel-nitrogen bonds.
Treated catalysts kept strong output after ninety thousand voltage cycles in membrane assemblies, holding a high current density at working voltage. The surface gained nickel while the layer beneath lost it, changing atomic coordination in the ordered alloy. Leaching of cheap metals normally poisons fuel cell membranes, so locking nickel in place matters. The authors offer pressure-driven redistribution as a general design strategy. Durable catalysts, they argue, are essential before fuel cell trucks can compete.
