| 摘要 |
<p>The present invention discloses porous fuel cell electrode structures, assemblies, and systems having one or more conformal metallic layers selectively deposited on one or more pore surfaces, as well as to various methods relating thereto. In one embodiment, the present invention is directed to an electrode structure for a fuel cell system, such as a hydrogen or a direct hydrocarbon fuel cell system, wherein the electrode structure comprises a substrat (210) or support structure having one or more discrete bulk porous matrix regions (220) disposed across a top surface (230) of the substrate. In this embodiment, each of the one or more discrete bulk porous matrix region is defind by acicular pores (240) that extend through the substrate or support structure. These pores define inner pore surfaces, which have a conformal electrically conductive layer thereon, as well as a plurality of catalyst par ticles.</p> |
