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.
L'invention concerne une plaque conductrice à champ de courant dans une pile à combustible à échange de protons, qui comprend une composition constituée d'une résine et de plusieurs fibres nanotubulaires de carbone présentant un diamètre moyen d'au moins 0,5 nm et jusqu'à 300 nm. Les fibres nanotubulaires de carbone ne dépassent pas une concentration d'environ 85 % en poids. La résine peut être d'un type thermoplastique, d'un type fluoré, d'un type thermodurcissable ou d'un type cristallin liquide.
