PNNL-led team designs highly active cobalt-based PGM-free catalyst for fuel cells A multi-institutional research team led by materials scientists from Pacific Northwest National Laboratory (PNNL) has designed a highly active and durable catalyst that doesn’t rely on costly platinum group metals (PGM) to spur the necessary chemical reaction. The new catalyst contains cobalt interspersed with nitrogen and carbon. When compared to a similarly structured catalyst made from iron—another promising, well-studied platinum substitute—the team found that the cobalt catalyst achieved a similar rea...

Stronger cobalt for fuel cells PNNL leads effort to improve reaction activity, increase durability of cobalt as a fuel cell catalyst DOE/Pacific Northwest National Laboratory By Mary Ann Showalter A multi-institutional research team led by materials scientists from Pacific Northwest National Laboratory (PNNL) has designed a highly active and durable catalyst that doesn't rely on costly platinum to spur the necessary chemical reaction. The new catalyst contains cobalt interspersed with nitrogen and carbon. When compared to a similarly structured catalyst made from iron--another promising, well...
