  • NICKEL-BASED CATALYST FOR FUEL CELL ANODE
    Publication number: 20240128472
    Abstract: A catalyst which is suitable for use in an anode of a fuel cell. The catalyst comprises, in at least partially reduced form, (i) nickel and (ii) molybdenum and, optionally, (iii) rhenium and/or (iv) at least one transition metal which is different from nickel, molybdenum and rhenium, supported on (v) electrically conductive carbon modified with one or more elements selected from the lanthanides, yttrium, tin and titanium. The weight ratio (i):((ii)+(iii)+(iv)) is at least 2:1.
