Title
(DE) ANODENSUBSTRAT FÜR EINE HOCHTEMPERATUR-BRENNSTOFFZELLE
(EN) ANODE SUBSTRATE FOR A HIGH-TEMPERATURE FUEL CELL
(FR) SUBSTRAT D'ANODE POUR PILE A COMBUSTIBLE HAUTE TEMPERATURE
Abstract
(DE)
Die Erfindung bezieht sich auf ein Anodensubstrat (1, 4) für eine Hochtemperaturbrennstoffzelle, die bezüglich der Methan-Dampf-Reformierungsreaktion eine nicht katalytisch wirkende sowie eine katalytisch wirkende Phase aufweist. Bei den bekannten Anodensubstraten läuft die Methan-Dampf-Reformierungsreaktion sehr schnell ab, so daß nachteilhaft große Temperaturunterschiede in der Brennstoffzelle entstehen. Zur Überwindung dieses Problems weist das Substrat erfindungsgemäß Bereiche reduzierter Katalysatorkonzentration zur Verzögerung der Reformierungsreaktion auf.
(EN)
The invention concerns an anode substrate (1, 4) for a high-temperature fuel cell which has a non-catalytic phase and a catalytic phase with respect to the methane - vapour reforming reaction. With known anode substrates, the methane - vapour reforming reaction occurs very rapidly, with the disadvantage that great differences in temperature occur in the fuel cell. In order to overcome this problem, the substrate according to the invention comprises areas in which the concentration of catalyst is reduced, in order to delay the reforming reaction.
(FR)
L'invention concerne un substrat d'anode (1, 4) pour pile à combustible haute température, qui comporte une phase à effet non catalytique et une phase à effet catalytique en ce qui concerne la réaction de reformage méthane-vapeur. Avec les substrats d'anode connus, la réaction de reformage méthane-vapeur se déroule rapidement, ce qui a pour inconvénient d'entraîner d'importantes différences de températures dans la pile à combustible. Pour remédier à ce problème, le substrat comporte, selon l'invention, des zones où la concentration en catalyseur est réduite afin de retarder la réaction de reformage méthane-vapeur.
