Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Her stellung einer Brennstoffzellen-Luftelektrode auf einem keramischen Elektrolyten.The invention relates to a method for Her position of a fuel cell air electrode on a ceramic electrolyte.
Hochtemperaturbrennstoffzellen mit Festelektrolyten sind beispielsweise in der DE-OS 39 07 485 beschrieben. Sol che Hochtemperaturbrennstoffzellen weisen auf einer der Hauptflächen eines keramischen Elektrolyten eine soge nannte Luftelektrode auf. Diese Elektrode muß einerseits ausreichend porös und dünn sein, um einen möglichst un gehemmten Sauerstofftransport zu gewährleistet, anderer seits muß sie ein guter elektrischer Leiter sein, um re lativ hohe Ströme führen zu können. High temperature fuel cells with solid electrolytes are described for example in DE-OS 39 07 485. Sol che high-temperature fuel cells point to one of the Main surfaces of a ceramic electrolyte a so-called called air electrode. This electrode must on the one hand be sufficiently porous and thin to be as un as possible inhibited oxygen transport to ensure others on the one hand, it must be a good electrical conductor in order to to be able to carry relatively high currents.
In der DE-OS 39 07 485 ist in Spalte 4, Zeile 32 bis 35 beschrieben, daß die als Luftelektrode ausgeführte Ka thode durch Plasmaspritzen oder Siebdruck auf den Elek trolyten aufgebracht werden kann, wobei eine Schichtdicke von 0,2 bis 1 mm angegeben ist. Diese Schichten werden bisher mit über Festkörperreaktionen hergestellte Pulver aus LaSrMnO3 hergestellt. Solche über Festkörperreaktio nen hergestellte Pulver zeigen eine im Vergleich zum Einkristall sehr geringe Leitfähigkeit. Dies ist vor al lem auf das mäßige Sinterverhalten, d. h. schlechten Schichtzusammenhalt bzw. Inhomogenitäten in der Schicht zurückzuführen. Um diese Nachteile auszugleichen, wurden bisher über Plasmaspritzen mehr als 100 µm dicke Schich ten auf zuvor sandgestrahlten Elektrolytscheiben aufge bracht. Um eine befriedigende Haftung zu erzielen, wurde sehr energiereich gespritzt. Dies führt zum teilweisen Verschluß der Poren und dadurch zu einer Hemmung des Sauerstofftransports und somit zu einer kinetischen Hem mung der Brennstoffzellen-Reaktion.In DE-OS 39 07 485 in column 4, lines 32 to 35 it is described that the air electrode designed as a method can be applied to the electrolyte by plasma spraying or screen printing, a layer thickness of 0.2 to 1 mm being indicated . Until now, these layers have been produced using powder made from LaSrMnO 3 by means of solid-state reactions. Such powders produced via solid-state reactions show a very low conductivity compared to single crystals. This is mainly due to the moderate sintering behavior, ie poor layer cohesion or inhomogeneities in the layer. In order to compensate for these disadvantages, more than 100 µm thick layers have previously been applied to previously sandblasted electrolyte discs by means of plasma spraying. In order to achieve satisfactory adhesion, very high-energy spraying was used. This leads to the partial closure of the pores and thereby to an inhibition of oxygen transport and thus to a kinetic inhibition of the fuel cell reaction.
Davon ausgehend liegt der Erfindung die Aufgabe zugrun de, ein verbessertes Verfahren zur Herstellung einer Brennstoffzellen-Luftelektrode auf einem keramischen Elektrolyten anzugeben.Proceeding from this, the invention is based on the object de, an improved method of making a Fuel cell air electrode on a ceramic Specify electrolytes.
Diese Aufgabe wird durch ein Verfahren gelöst zur Her stellung einer Brennstoffzellen-Luftelektrode auf einem keramischen Elektrolyten, das nachstehende Verfahrens schritte aufweist:This problem is solved by a method for the manufacture position of a fuel cell air electrode on a ceramic electrolyte, the procedure below steps:
- a) Anrühren einer Siebdruckpaste aus einem naßchemisch z. B. durch Spraypyrolyse hergestellten Perowskit des Typs La1-xMx¹M²O₃(Mx¹=Ca, Sr; M²=Mn, Ni, Cr, Co) unter Zusatz von Terpineol, einem Binder, einem Plastifizierer und einer Dispergierhilfe, a) stirring a screen printing paste from a wet chemical z. B. perovskite of the type La 1-x M x ¹M²O₃ (M x ¹ = Ca, Sr; M² = Mn, Ni, Cr, Co) prepared by spray pyrolysis with the addition of terpineol, a binder, a plasticizer and a dispersing aid,
- b) Aufbringen einer dünnen, z. B. 30 µm dicken Schicht der Paste auf eine gesinterte, nicht sandgestrahlte Elektrolytscheibe, undb) applying a thin, e.g. B. 30 micron thick layer the paste onto a sintered, not sandblasted Electrolyte disc, and
- c) Einbrennen der Schicht bei etwa 1400°C.c) baking the layer at about 1400 ° C.
Mit dem erfindungsgemäßen Verfahren hergestellte Luft elektrodenschichten zeigen eine Reihe von Vorteilen. Die erfindungsgemaß hergestellte und verwendete Siebdruckpa ste ist sehr sinteraktiv und führt bei relativ niedriger Sintertemperatur zu einer extrem gut haftenden Schicht. Es ist keine Vorbehandlung der Unterlage durch Sand strahlen erforderlich. Mit einem Rasterelektronen-Mikro skop angefertigte Schliffbilder lassen selbst bei 2000facher Vergrößerung keine Korngrenzen erkennen. Dies läßt darauf schließen, daß eine merkliche Ausbil dung von Verunreinigungen enthaltenden Korngrenzen unter blieben ist. Eine solche, als Zeichnung beigefügte Auf nahme zeigt eine für einen hinreichenden Sauerstoff transport benötigte Porösität von etwa 50%. Außerdem zeigt die REM-Aufnahme die Ausbildung ausgedehnter, für die elektrochemische Umsetzung wesentlicher 3-Phasen grenzen.Air produced with the method according to the invention Electrode layers show a number of advantages. The Screen printing pa produced and used according to the invention ste is very sinter active and performs at relatively low Sintering temperature to an extremely well adhering layer. It is not pretreatment of the surface with sand blasting required. With a scanning electron micro Skop-made micrographs allow themselves 2000 times magnification no grain boundaries detect. This suggests that a noticeable training grain boundaries remained. One such, attached as a drawing Acceptance shows one for sufficient oxygen transport required porosity of about 50%. Furthermore the REM image shows the training for extended the electrochemical implementation of essential 3 phases limit.
Ein anderer Vorteil ist darin zu sehen, daß für die sehr dünnen Elektrodenschichten nur eine kleine Materialmenge erforderlich ist.Another advantage is that for the very thin electrode layers only a small amount of material is required.
Die elektrische Leitfähigkeit der nach dem erfindungsge mäßen Verfahren hergestellten Schicht ist besonders gut. In Versuchen wurde bei einer Betriebstemperatur von 1000°C eine Leitfähigkeit von 225 Scm-1 gemessen.The electrical conductivity of the layer produced by the method according to the invention is particularly good. In experiments, a conductivity of 225 Scm -1 was measured at an operating temperature of 1000 ° C.
Nachstehend wird ein Ausführungsbeispiel für das erfin dungsgemäße Verfahren beschrieben. An embodiment of the invention is described below described method according to the invention.
In dem Ausführungsbeispiel wurde ein Perowskit-Pulver aus La0,84Sr0,16MnO₃ der Firma Merck verwendet, das durch Spraypyrolyse hergestellt wurde. Dieses Pulver ist aufgrund seiner Feinheit extrem sinteraktiv. Wegen sei ner hohen Reinheit wird eine Ausbildung von Korngrenzen mit hohen Widerständen nicht beobachtet. Aufgrund der hohen Homogenität des Ausgangspulvers sind die Bulk-Ei genschaften (Leitfähigkeit, Zusammensetzung etc.) über die komplette Elektrode sehr einheitlich. Das Pulver wurde mit Terpineol, Ethocel 10 der Fa. Dow Chemicals als Binder, Triolein als Plastifizierer und Dibutylphtha lat als Dispergierhilfe zu einer Siebdruckpaste ange rührt. Der Feststoffgehalt lag idealerweise bei 65%, er kann aber auch nach oben bis etwa 80% und nach unten bis etwa 55% variiert werden.In the exemplary embodiment, a perovskite powder made of La 0.84 Sr 0.16 MnO₃ from Merck was used, which was produced by spray pyrolysis. This powder is extremely sinter-active due to its fineness. Because of its high purity, the formation of grain boundaries with high resistances is not observed. Due to the high homogeneity of the starting powder, the bulk properties (conductivity, composition, etc.) are very uniform across the entire electrode. The powder was mixed with terpineol, Ethocel 10 from Dow Chemicals as a binder, triolein as a plasticizer and dibutyl phthalate as a dispersing aid to form a screen printing paste. The solids content was ideally 65%, but it can also be varied up to about 80% and down to about 55%.
Die so hergestellte Paste wurde dann auf eine gesinter te, nicht sandgestrahlte Elektrolytscheibe mit einer Dicke von etwa 30 µm im grünen Zustand aufgetragen und bei 1400°C eingebrannt. Es wurde eine etwa 10 µm dicke, gut haftende Schicht erzielt.The paste thus produced was then sintered te, not sandblasted electrolyte disc with a Thickness of about 30 microns applied in the green state and Baked at 1400 ° C. It was about 10 microns thick well adhering layer achieved.
Da die Schicht eine hohe elektrische Leitfähigkeit auf weist, kann sie z. B. als stromführende Schicht einer im Sinne der Patentanmeldung P 41 04 838.5 zweigeteilten Luftelektrode verwendet werden.Because the layer has high electrical conductivity points, it can e.g. B. as a current-carrying layer in In terms of patent application P 41 04 838.5 two-part Air electrode can be used.
