Patent ID: 7763373

Claim:
A method for producing an electrode arrangement for use in a fuel cell, said method comprising: providing a filament comprising a supporting core and a plurality of webs extending radially from said core and axially along a length of said filament, said filament forming a radially internal, electrically conductive first electrode, said filament comprising a hollow fiber provided with a catalyst, said hollow fiber having an outer envelope surface; providing a membrane over said outer envelope surface, said membrane having a radially internal envelope surface separated from said core by said webs, said membrane and said webs of said filament together forming a plurality of separate flow channels such that said membrane defines a portion of each of said separate flow channels and said filament defines another portion of said each of said separate flow channels; pulling a woven stocking over said filament so that said woven stocking surrounds at least a portion of said filament and fits onto said at least a portion of said filament; and pulling said woven stocking over said membrane, said woven stocking forming a second electrode.
