Hydrogen oxidation reactions in hydroxide exchange membrane fuel cells have slow kinetics. Switching from platinum group metal (PGM) electrocatalysts to those that are PGM-free is a challenging task as the latter are prone to oxidation. Now, stable and active nickel–molybdenum–niobium catalysts are introduced for this type of fuel cell.
