abstract = {For the investigation of the reactivity of alternative
solid oxide cell air electrode materials with forsterite
(Mg2SiO4), a magnesium silicate doped with Zn and Ca, five
different phase materials were chosen: two
Ruddlesden–Popper phase materials: La4Ni3O10 (L4N3) and
La3Ni2O7 (L3N2) and three titanium-based perovskite
materials: SrTiO3 (STO), SrTi0.75Fe0.25O3 (STF25) and
CaTi0.9Fe0.1O3 (CTF). Forsterite was chosen as a support
material for the fuel cell, as it is abundant and therefore
relatively inexpensive. For the investigation of their
reactivity, different types of samples were prepared: mixed
pellets, double-layered pellets and screen-printed electrode
inks on forsterite green substrates, which were subsequently
co-sintered at T = 1300 °C. These samples and their
cross sections were then studied using XRD, SEM, EDS and TEM
lamella point analysis. Consequently, the impedance spectra
were acquired to determine their electro-catalytic
performance. The two Ruddlesden–Popper phase materials
L4N3 and L3N2 are of high interest due to their
thermodynamic stability and high electro-catalytic activity,
resulting in a very low polarization resistance. However,
this polarization resistance is increased when mixing with
forsterite material. In case of the three titanium-based
perovskites, the electro-catalytic activity is of less
interest due to high polarization resistances.},
