      abstract     = {One way to improve the mechanical properties of solid oxide
                      fuel cells is the development of metal supported designs.
                      This type of SOFC offers improved thermal shock resistance,
                      reduced temperature gradients due to the greater thermal
                      conductivity of the metal, and lower operating temperatures.
                      Switching from ceramic supports to metal supports also
                      allows the uses of conventional metal joining and forming
                      techniques and could significantly reduce the material and
                      manufacture costs. However, one persistent problem needs to
                      be solved: inter-diffusion of chemical elements contained in
                      the metal substrates and in the anodes of SOFC leads to
                      degradation, which is to be prevented by protective
                      coatings. In order to address the issues of sintering and
                      delamination for metal supported SOFC, the deposition of
                      gadolinia doped ceria on metal substrates made of Crofer 22
                      APU has been done by electron beam evaporation and reactive
                      spray deposition technique, as two direct deposition
                      techniques that will not require a sintering step,
                      respectively. Additionally, the effect of ion-assistance on
                      layers made by electron beam evaporation was studied.
                      Because metal supported fuel cells aim at low/intermediate
                      operating temperatures, reducing the thickness of these
                      protective coatings is crucial, since layer thickness is
                      directly correlated to its ohmic resistance. A layer of
                      nickel was applied by magnetron sputtering to prove the
                      effectiveness of the deposited diffusion barrier layers. (C)
