Abstract
An electrically conductive flow-field plate in a proton exchange membrane fuel cell comprises a composition made of a resin and a plurality of carbon nanotubular fibers having an average diameter is at least about 0.5 nm and up to about 300 nm. The carbon nanotubular fibers are present at not more than about 85 wt. %. The resin can be of a thermoplastic type, a fluorinated type, a thermosetting type and a liquid crystalline type.
