  • Patent number: 11398630
    Abstract: The present disclosure relates to a method of generating energy. This method involves providing a fuel cell comprising anode and cathode electrodes; a separator positioned between the anode and cathode electrodes; and anode and cathode catalysts. The anode catalyst comprises (i) a low-loading of platinum group metals (PGMs) supported on a Group 4-6 transition metal carbide (TMC) or nitride (TMN); (ii) an alloy or physical mixture comprising a Group 10 transition metal selected from Pt, Pd, and Ni and one or more of the following elements: Pt, Pd, Ni, Ir, Rh, Ru, Fe, Re, Sn, W, Mo, Ta, and Nb; or (iii) mixtures thereof. According to the method, a liquid anode fuel comprising one or more hydrazide compounds is added to the fuel cell to generate energy from the liquid anode fuel. Also disclosed is a fuel cell for generating energy from a liquid anode fuel comprising one or more hydrazide compounds.
