PNNL-led team designs highly active cobalt-based PGM-free catalyst for fuel cells

DECEMBER 15, 2020
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
