For use in a high temperature fuel cell are special requirements for glass solders because of the prevailing high temperatures. glass solders are required when adding individual fuel cells and also when adding individual cells a so-called fuel cell stack. The coincidences the connected components, mostly ceramics and / or Metals have to be stable up to temperatures of 1000 ° C gas-tight and electrically insulating.

For this it is regularly necessary that the thermal Coefficient of expansion of the glass solder used as good as possible to the components to be connected fits.  

As a principle suitable glass for this task lot has the BAS (barium aluminum silicate) glass exposed. It has been found that for the Gasdich activity of the glass solder the crystallization process, the Crystal phases and their proportion and the resulting Porosity are critical. By To MgO could improve the tendency to crystallize sert and the volume crystallization can be increased.

The glass solder according to claim 1 is based on a mixture of BaO, CaO and SiO 2 with the addition of Al 2 O 3 . This mixture is particularly suitable for use in a high-temperature fuel cell as a joining material for a gas-tight and temperature-resistant connection, for example between a ceramic and a metal. The mixture allows by variation of the contents of the individual components to adjust the properties of the glass solder, such as. B. the coefficient of thermal expansion to that of the materials to be joined. This can be used to regularly prevent thermal tensions between the materials, which usually occur during operation and when starting and shutting down a fuel cell.

The glass solders according to the invention can be described in their compositions using a ternary triangle diagram, the three corners of the diagram representing the pure components BaO, CaO and SiO 2 and the content of the fourth component Al 2 O 3 being kept constant.

An advantageous embodiment of the glass solder has a BaO content of 20 to a maximum of 80% by weight, in particular 45 to 55% by weight, in the ternary mixture of BaO-CaO-SiO 2 . Further advantageous compositions of the ternary mixture BaO-CaO-SiO 2 see contents of CaC from <0 to a maximum of 30% by weight, in particular from 7 to 15% by weight, and contents of SiO 2 from 20 to a maximum of 65%. -%, in particular from 35 to 45% by weight. The Al 2 O 3 content is advantageously not more than 10% by weight, based on the four-component mixture.

Another advantageous embodiment of the glass solder sees an addition of oxides with elements, especially right of two and / or trivalent ions of groups VA to VIIA and IIB to VB, to the four-component mixture in front. This can have the beneficial effects, such as for example an increase in the glass transition temperature tur, the softening temperature and in particular the Thermal expansion coefficient can be achieved. more You can regularly add additional oxides the flow properties and the crystallization properties be improved.

Suitable oxides with divalent ions are: SrO, MnO, ZnO and PbO. Suitable oxides with three valuable ions are: B 2 O 3 and La 2 O 3 . However, higher-quality oxides, such as TiO 2 or V 2 O 5 , are also possible as additives. According to the invention, the content of added oxides is limited to a maximum of 20% by weight, based on the overall system.

To produce the glass solder according to the invention the selected components according to their ge desired composition first in powder form mixes (mixed powder) and such a temperature exposed to the fact that there is a perfect up  melting of the particles comes. Typical temperature range che are around 1300 to 1500 ° C. Then will the melted mixed powder (glass solder) cooled. The glass solder can be used both as a fitting or for example also as a massive block the.

For the actual joining process, the solder is between introduced the components to be joined. It can Lot already as a finished molding or as a paste with the glass ground from the block, for example lot applied or arranged accordingly. The actual process takes place in a further temperature step Liche joining process, in which the joint connection and the glass solder to the glass ceramic tallisiert. The temperatures for the joining process are regularly in the range of 700 to 1000 ° C, especially in the range of 800 to 900 ° C, i.e. significantly lower than when melting the mixed powder.

Table 2 advantageous compositions for which he glass solders according to the invention.

In Fig. 1, the coefficient of thermal expansion α tech for various glass solders and the stack components, in particular steel substrate and represented as a function of temperature. An anode material comprising a cermet made of nickel and zirconium oxide was examined as the substrate. With increasing temperature, the thermal expansion coefficient α tech of the materials also increases. Even at low temperatures, the stack components have coefficients of thermal expansion in the range from 10 to 11 × 10 -6 per K, and reach values in the range from 13 to 14 × 10 -6 per K at temperatures of 900 to 1000 ° C partially have an adapted coefficient of thermal expansion. The glass solders presented here achieve thermal expansion coefficients in the range of 11 to 12 × 10 -6 per K at temperatures of 900 to 100 ° C. Furthermore, the temperature range in which the operation of a high-temperature fuel cell takes place (750-950 ° C ), there is no sudden change in the coefficient of thermal expansion.

Fig. 2 shows the coefficient of thermal expansion for the glass solders listed in Table 2 as a function of temperature. All the compositions shown advantageously have a thermal expansion coefficient of more than 11 × 10 -6 per K at temperatures above 800 ° C.

Fig. 3 shows a triangle diagram for the composites of the ternary mixture of BaO-CaO-SiO 2 with the representation of the area which is particularly advantageous for the glass solders according to the invention. For the glass solders according to the invention, the advantageous compositions result from the ternary region shown in the triangular diagram with the addition of up to 10% by weight of Al 2 O 3 , based on the four-component mixture then present.

FIG. 4 shows a section of the phase diagram of the four-substance system BaO-CaO-SiO 2 with 5% by weight Al 2 O 3 . The coefficients of thermal expansion of the constitutional phases in the corners have been taken from the literature. The entire glass formation area in this system was examined both with experimental (adhesion tests, gas tightness tests, heating microscope, dilatometer and X-ray diffraction) and with theoretical methods (calculation of the mineral phases to be expected in the physico-chemical equilibrium state). It was shown that only a certain section of the system provides suitable solders. The glasses in the CaO-SiO 2 corner (CS), for example, are not suitable because of their low coefficient of thermal expansion. Glasses near 2BaO.3SiO 2 (B 2 S 3 ) and 2CaO.BaO.3SiO 2 (C 2 BS 3 ) crystallize too quickly (as observed in the heating microscope) and adhere poorly to the steel 1.4742. The glass compositions near glass 24 adhere well to the steel, but they have a fairly low coefficient of thermal expansion. The most interesting area is hatched horizontally in the picture. Here, both good adhesion and a high coefficient of thermal expansion were found to be advantageous. It is known from the literature that BS 2 and B 2 S 3 have a high coefficient of thermal expansion. In the experiment, that of C 2 BS 3 was also determined to be high at 11.3 × 10 -6 K -1 . Therefore, the selected glass composition should lie in the triangle BS 2 -B 2 S 3 -C 2 BS 3 .

The effects of the various additives examined for glass ceramic solders for the SOFC are summarized in Table 1 below:

Table 2 also gives particularly advantageous compositions in% by weight for which he glass solders according to the invention again, in which the four-component system has additional oxides will give.
