| 520 | _ | _ | |a Planar Solid Oxide Fuel Cells (SOFCs) are usually sealed and joined using glass solder. The sealing material needs to be electrically isolating, mechanically stable at working temperature and during thermal-cycling, and the thermal expansion coefficient needs to be adapted to the materials connected. Glass solder has evolved as the primary sealing material, since it serves the demands best. The sealing of SOFCs is done in a furnace. The sealing and joining temperature must not be significantly higher than the working temperature of the SOFC, otherwise it would get damaged. The choice of glass solders is therefore limited. Furthermore, furnace joining takes a lot of time. Aiming at an economical production, the application of a laser as a heat source for successful joining was examined. This was done to industrialize the SOFC, in the scope of an EU-project for the development of MMLCR=SOFCs (Working towards Mass Manufactured, Low Cost and Robust Solid Oxide Fuel Cell stacks). Without preparation, laser joining can theoretically be done in a few minutes, which bears the potential of cheaper joining. Within this thesis, it was examined how joining with a laser could be done with the same quality of bonds as in furnace joining. The glass solders for laser joining do not need to be the same as those for furnace joining. Thus, higher joining temperatures can be reached with a laser without damaging the SOFC. In this way, glass solders with higher transformation temperatures can be used. Such glass solders can have better properties regarding other demands. Joining of glass solder and steel with a laser was successfully done. The geometry of the steel frames of an SOFC is a big challenge for laser joining, since wetting by glass solder is hardly possible. Successful sealing with a laser also requires thicker steel sheets than those used in mass production. |
