A metal foam supported solid oxide fuel cell (SOFC) with yttria-stabilized zirconia (YSZ) and gadolinium doped ceria (GDC) bi-layer electrolyte is proposed. The prepared cells are supported by NiCrAl metal foam, which has been impregnated with La-substituted SrTiO3 (LST) as electrical conductive material. An LST-GDC anode functional layer was tape cast into green tape and then laminated onto the metal foam support. The measured thickness of the anode functional layer is approximately 20 μm after calcination at 1000 oC. Gas-tight YSZ electrolyte layers were deposited by vacuum plasma spray (VPS). Alternatively, porous YSZ layers were dip-coated with a fine suspension containing YSZ nanoparticles in order to obtain thin-film electrolytes. Successively, a gas-tight GDC electrolyte was deposited by EB-PVD method. The thickness of the gas-tight VPS YSZ electrolyte and the thin film YSZ-GDC bi-layer electrolyte was approximately 100 μm and 3 μm, respectively. The pore size distribution of NiCrAl foam supported substrates was characterized by mercury porosimetry analysis, the microstructure was demonstrated with SEM and the gas-tightness of the half cells was evaluated.
