Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Katalysators.The The invention relates to a catalyst for in a fuel cell stack arranged fuel cell according to the preamble of the claim 1. Furthermore, the invention relates to a process for the preparation such a catalyst.
Bei Brennstoffzellen, welche in Form eines Brennstoffzellenstapels angeordnet sind, gibt es eine Anzahl von in unterschiedlicher Weise ausgebildeten Katalysatoren zur internen Reformierung eines den Brennstoffzellen zugeführten Brenngases innerhalb des Brennstoffzellenstapels. Die interne Reformierung des Brenngases dient einerseits zu dessen Aufbereitung in eine von den Brennstoffzellen nutzbare Form und andererseits einer internen Kühlung der Brennstoffzellen aufgrund des endothermen Charakters der am Katalysator stattfindenden Reformierungsreaktion. Unter Katalysator wird hier und im Folgenden ein Katalysatormaterial und Trägerstruktur umfassendes Bauteil verstanden.at Fuel cells, which arranged in the form of a fuel cell stack There are a number of differently engineered catalysts for the internal reforming of a fuel cell supplied Fuel gas within the fuel cell stack. The internal reform the fuel gas serves on the one hand for its preparation in one of the fuel cell usable form and on the other hand an internal Cooling of the fuel cells due to the endothermic nature the reforming reaction taking place on the catalyst. Under catalyst is here and below a catalyst material and support structure comprehensive Component understood.
Die
Die Aufgabe der Erfindung ist es, einen Katalysator der eingangs genannten Art zu schaffen, welcher eine hohe Effektivität aufweist. Weiterhin soll ein Verfahren zur Herstellung eines solchen Katalysators angegeben werden.The The object of the invention is a catalyst of the aforementioned To create kind, which has a high effectiveness. Furthermore, a method for producing such a catalyst is given become.
Durch die Erfindung wird ein Katalysator für in einem Brennstoffzellenstapel angeordnete Brennstoffzellen, welcher zur internen Reformierung eines den Brennstoffzellen zugeführten Brenngases innerhalb des Brennstoffzellenstapels angeordnet ist, mit in Form von langgestreckten Stäben ausgebildeten Katalysatorelementen und einem Basisteil, das eine Anzahl von jeweils zur Aufnahme der Katalysatorelemente vorgesehenen Raumbereichen aufweist, geschaffen, wobei die Katalysatorelemente zum Austausch in ihrer Längsrichtung aus dem Brennstoffzellenstapel entnehmbar und in diesen einsetzbar sind.

According to the invention it is provided that the catalyst elements define a rod shape Carrier element with an applied on it in the form of a layer Include catalyst material.
Gemäß einer Ausführungsform der Erfindung ist es vorgesehen, dass das Trägerelement durch eine Drahtwendel gebildet ist.According to one Embodiment of the invention it is provided that the Carrier element is formed by a wire coil.
Die Ausbildung des Trägerelements in Form einer Drahtwendel ist strömungstechnisch vorteilhaft, da sie eine große katalytisch wirksame Oberfläche bei geringem Strömungswiderstand aufweist.The Formation of the carrier element in the form of a wire helix is aerodynamically advantageous because it has a large catalytically active surface with low flow resistance having.
Gemäß einer anderen Ausführungsform der Erfindung kann das Trägerelement durch ein Glasröhrchen gebildet sein. Ein Vorteil hiervon ist eine hohe thermische Stabilität des durch das Glasröhrchen gebildeten Trägerelements.According to one Another embodiment of the invention, the support member be formed by a glass tube. An advantage of this is a high thermal stability of the through the glass tube formed carrier element.
Das Katalysatormaterial kann durch einen Haftvermittler mit der Oberfläche der das Trägerelement bildenden Drahtwendel verbunden sein, wobei der Haftvermittler insbesondere ein Emailpulver oder ein anorganischer Klebstoff sein kann.The Catalyst material can by a bonding agent with the surface the wire helix forming the carrier element is connected, wherein the adhesion promoter in particular an enamel powder or an inorganic Adhesive can be.
Auch bei der Ausbildung des Trägerelements in Form eines Glasröhrchens kann das Katalysatormaterial durch einen Haftvermittler mit der Oberfläche desselben verbunden sein.Also in the formation of the support member in the form of a glass tube can the catalyst material by an adhesion promoter with the Surface of the same be connected.
Alternativ kann das Katalysatormaterial direkt mit der Oberfläche des Glasröhrchens verbunden sein.alternative The catalyst material can be directly connected to the surface be connected to the glass tube.
Das Katalysatormaterial kann auf die äußere Oberfläche des Glasröhrchens aufgebracht sein.The Catalyst material can affect the outer surface be applied to the glass tube.
Das Katalysatormaterial kann auch auf die äußere und die innere Oberfläche des Glasröhrchens aufgebracht sein.The Catalyst material can also affect the outer and applied the inner surface of the glass tube be.
Das den Katalysator aufnehmende Basisteil kann durch einen Anodenstromkollektor der Brennstoffzelle gebildet sein.The The catalyst receiving base may be replaced by an anode current collector be formed of the fuel cell.
Weiterhin werden durch die Erfindung Verfahren zur Herstellung eines Katalysators der vorgenannten Art geschaffen, wobei es vorgesehen ist, dass das Katalysatormaterial durch Pulverbeschichtung auf die Oberfläche des Trägerelements aufgebracht wird.Farther The invention relates to processes for the preparation of a catalyst of the aforementioned type, wherein it is provided that the Catalyst material by powder coating on the surface the carrier element is applied.
Bei Verwendung eines Haftvermittlers kann es vorgesehen sein, dass zuerst der Haftvermittler auf die Oberfläche des Trägerelements aufgetragen wird, und dass dann das Katalysatormaterial auf den Haftvermittler aufgebracht wird.at Using a primer it can be provided that first the adhesion promoter on the surface of the support element is applied, and then that the catalyst material on the bonding agent is applied.
Alternativ kann es vorgesehen sein, dass das Katalysatormaterial mit dem Haftvermittler gemischt und dann die Mischung auf die Oberfläche des Trägerelements aufgebracht wird.alternative It may be provided that the catalyst material mixed with the bonding agent and then the mixture on the surface of the support member is applied.
Bei Verwendung eines Glasröhrchens als Trägerelement kann es vorgesehen sein, dass das Glasröhrchen bis zum Erweichen erhitzt wird, und dass das Katalysatormaterial auf die erweichte Oberfläche des Glasröhrchens aufgebracht wird.at Use of a glass tube as a carrier element it can be provided that the glass tube until the Softening is heated, and that the catalyst material on the softened surface of the glass tube applied becomes.
Im Folgenden werden Ausführungsbeispiele des erfindungsgemäßen Katalysators und seiner Herstellung anhand der Zeichnung erläutert. Es zeigen:in the Below are embodiments of the invention Catalyst and its preparation explained with reference to the drawing. Show it:
