Title (EN) TUBULAR SOLID OXIDE FUEL CELL CURRENT COLLECTOR
(FR) COLLECTEUR DE COURANT POUR PILE A COMBUSTIBLE A OXYDE SOLIDE TUBULAIRE
Abstract:
(EN) A tubular electrochemical reactor includes a porous metal support tube (19) coated on the inside with a porous first electrode (21), the first electrode coated on the inside with a dense electrolyte (23). The dense electrolyte (23) is coated on the inside with a second electrode (25), wherein the second electrode provides a tubular inner surface. A tubular spring coil current collector (27) is disposed concentrically within the second electrode (25) and in tangential electrical contact with the tubular inner surface. The spring coil has an elastic modulus between 1,000,000 and 50,000,000 psi, a diameter between 0.4 to 0.8 inches larger in its normal state than a diameter of the inner surface, and a number of rums per inch (pitch) of 1 to 35 per inch.
(FR) Un réacteur électrochimique tubulaire comprend un tube support en métal poreux (19), revêtu intérieurement d'une première électrode poreuse (21), la première électrode étant enrobée intérieurement par un électrolyte dense (23). L'électrolyte dense (23) est revêtu, sur l'intérieur, d'une seconde électrode (25), cette dernière constituant une surface intérieure tubulaire. Un collecteur de courant à spire de ressort tubulaire (27) est disposé concentriquement à l'intérieur de la seconde électrode (25) et en contact électrique tangentiel avec la surface intérieure tubulaire. La spire de ressort a un module d'élasticité compris entre 1.000.000 et 50.000.000 psi, un diamètre de l'ordre de 0,4 à 0,8 pouce, supérieur, dans son état normal au diamètre de la surface intérieure, et un nombre de tours par pouce (pas) de 1 à 35 par pouce.
