Abstract
An anode for hydrogen oxidation in a fuel cell is formed from a host matrix including at least one transition element which is structurally modified by the incorporation of at least one modifier element to improve its catalytic properties. The catalytic body is based on a disordered non-equilibrium material designed to have a high density of catalytically active sites, resistance to poisoning, and long operating life. Modifier elements, including Ti, Mo, Zr, Mg, V, Si or Al, structurally modify the local chemical environments of a nickel or other transition element host matrix to form the catalytic materials of the anode. The improved low overvoltage catalytic materials of the anode of the present invention increase the operating efficiencies of fuel cells employing such anodes. The catalytic materials can be deposited as a layer on the surface of porous electrode substrates to form a gas diffusion anode or can be formed as a gas diffusion electrode.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
