Title
(EN) REFORMING CATALYST PATTERN FOR FUEL CELL OPERATED WITH ENHANCED CO2 UTILIZATION
(FR) MOTIF DE CATALYSEUR DE REFORMAGE POUR PILE À COMBUSTIBLE FONCTIONNANT AVEC UNE UTILISATION AMÉLIORÉE DU CO2
Abstract
(EN)
A reforming element for a molten carbonate fuel cell stack and corresponding methods are provided that can reduce or minimize temperature differences within the fuel cell stack when operating the fuel cell stack with enhanced CO2 utilization. The reforming element can include at least one surface with a reforming catalyst deposited on the surface. A difference between the minimum and maximum reforming catalyst density and/or activity on a first portion of the at least one surface can be 20% to 75%, with the highest catalyst densities and/or activities being in proximity to the side of the fuel cell stack corresponding to at least one of the anode inlet and the cathode inlet.

L'invention concerne un élément de reformage pour un empilement de piles à combustible à carbonate fondu et des procédés correspondants qui peuvent réduire ou réduire au minimum les différences de température à l'intérieur de l'empilement de piles à combustible lors du fonctionnement de l'empilement de piles à combustible avec une utilisation améliorée du CO2. L'élément de reformage peut comprendre au moins une surface sur laquelle est déposée un catalyseur de reformage. Une différence entre la densité et/ou l'activité du catalyseur de reformage minimale et maximale sur une première portion de ladite surface peut être de 20 % à 75 %, les densités et/ou activités de catalyseur les plus élevées se trouvant à proximité du côté de l'empilement de piles à combustible correspondant à au moins l'une parmi l'entrée d'anode et l'entrée de cathode.
