Hydrogen oxidation reaction

Nickel catalysts for affordable fuel cells

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.
