Abstract
The present invention discloses nanowires for use in a fuel cell comprising a metal catalyst deposited on a surface of the nanowires. A membrane electrode assembly for a fuel cell is disclosed which generally comprises a proton exchange membrane, an anode electrode, and a cathode electrode, wherein at least one or more of the anode electrode and cathode electrode comprise an interconnected network of the catalyst supported nanowires. Methods are also disclosed for preparing a membrane electrode assembly and fuel cell based upon an interconnected network of nanowires.
Claims4
A nanowire for use in a fuel cell wherein the nanowire comprises a core which comprises silicon and at least one shell layer which comprises silicon carbide (SiC) having a catalyst metal and/or proton conducting coating deposited thereon.
