Claims20
A method of improving hydrogen oxidation rate in a catalyst for use in AFCs comprising the steps of,
- providing a catalyst substrate;
- disposing on the catalyst substrate a material having balanced active sites for adsorption/dissociation of H2 and adsorption of OHad, thereby enhancing the hydrogen oxidation rate for use in AFCs.
A catalytic article of manufacture, comprising:
- a substrate for a catalyst;
- and
- a coating disposed on the substrate wherein the coating comprises an oxophyllic material having a set of active sites providing a balanced adsorption/dissociation for H2 and adsorption of OHad, thereby enhancing the hydrogen oxidation rate.
