The subject matter of the invention is a double-sided adhesive metal-based tape for use as contacting aid for SOFC fuel cells. The new adhesive tape means a significant simplification in comparison to the present use of a liquid adhesive. The simple, low-cost production without special tools and the simplicity of use in a fuel cell stack provide an excellent option for minimizing costs during assembly and permitting large- scale production. The double-sided metal-based adhesive tape is suitable for simplifying the construction of cell bundles. The advantages of the metal-based adhesive tape in comparison to conventional contacting are a better control of the layer thickness, a cleaner and more accurate application without curing time and the potential for automation of large-scale production.

L'invention concerne une bande métallique adhésive double face s'utilisant comme moyen de mise en contact dans des piles à combustible à oxyde solide (SOFC). La nouvelle bande adhésive apporte une importante simplification par rapport à l'utilisation actuelle d'une colle liquide. Sa fabrication simple et économique sans outil particulier et son application facile dans un empilement de cellules électrochimiques offrent une bonne possibilité de production à l'échelle industrielle et de minimisation des coûts de conception. La bande métallique adhésive double face est appropriée pour simplifier la conception de groupes de cellules. Les avantages de la bande métallique adhésive par rapport aux systèmes de mise en contact classiques sont un meilleur contrôle de l'épaisseur des couches, une application propre et précise sans temps de durcissement et la possibilité d'automatisation lors d'une production à l'échelle industrielle.
