Some examples of a method for manufacturing an electrode material for electrolytic hydrogen generation are described. Tungsten salt and nickel salt are mixed in a determined molar ratio on a carbon support by effectively controlling synthesis temperature and composition. Water and adsorbed oxygen, produced by mixing the tungsten salt and nickel salt are removed. Then, methane gas is flowed over the mixture resulting in the electrode material. The electrode material is suitable for use as a catalyst in electrolytic hydrogen generation processes, for example, at an industrial scale, to produce large quantities of hydrogen.

A supported catalyst includes a plurality of support particles that each include a carbon support and a layer disposed around the carbon support. The layer is selected from a metal carbide, metal oxycarbide, and combinations thereof. A catalytic material is disposed on the layers of the support particles.

A fuel cell supported catalyst includes an underlying support structure having at least one of a metal oxide and a metal phosphate. Catalyst particles are arranged onto and in engagement with the support structure. An intermediate conductive, corrosion-resistant layer, such as boron-doped-diamond, is arranged onto and in engagement with the support structure to surround the catalyst particles. The supported catalyst is produced by depositing the intermediate layer onto the support structure after the catalyst particles have been deposited on the underlying support structure, in one example. In another example, voids are provided in the intermediate layer, which has been deposited onto the underlying support structure, to subsequently receive the catalyst particles.

The incorporation of tungsten-containing hydrogen spillover materials into a composite fuel cell anode can be helpful in preserving the carbon catalyst support materials in the fuel cell cathode during periods of hydrogen starvation. Preferred examples of such tungsten-containing hydrogen spillover materials are tungsten oxides and tungsten silicides. These materials, when physically mixed with catalyst-loaded carbon support particles in a composite anode, have shown the ability to promote hydrogen storage in amounts that, during a disruption of hydrogen gas flow, can postpone an anodic potential excursion into the oxygen evolution region for a period of at least several seconds.
