This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Low-cost carbon fiber paper structures are used as precursor for preparation of an all-carbon product that has a high electric conductivity and porosity and be processed in a continuous reel-to- reel mode. These paper materials are further impregnated and processed to adjust the final product properties. This all-carbon electrode substrate is not brittle thereby avoiding the main disadvantage of the prior art.

La présente invention concerne des substrats d'électrodes pour piles électrochimiques, notamment pour des piles à combustible basse température et leurs procédés de fabrication. On utilise des structures peu coûteuses en fibres de carbone comme précurseurs pour la préparation d'un produit entièrement composé de carbone, hautement conducteur d'électricité et de porosité élevée pouvant être traité en continu, en mode bobine/bobine. Ces matériaux de papier subissent un traitement d'imprégnation complémentaire et un complément d'ouvraison visant à leur donner leurs propriétés définitives. Lesdits substrats d'électrode ne sont pas cassants et n'ont donc pas les désavantages de l'état de la technique antérieur.
