Solid Oxide Fuel Cells (SOFC) are leading the way in distributed clean energy generation. In order to operate efficiently and reliably, a fuel cell needs to remain very stable at high operating temperatures. Oerlikon Metco’s solutions — state-of-the-art plasma spray equipment and advanced ceramic materials — provide a cost-efficient and flexible processing method for SOFC production.

Clean and Efficient Power with SOFC Thermal Spray Solutions

Prevention of cathode poisoning by chromium (Cr) ion transport from the interconnect, unwanted cathode-electrolyte reactions, and stable oxygen reduction reaction (ORR) in the cathode-electrolyte triple phase boundary (TPB) are essential for the high performance of a fuel cell.

Plasma spray coatings with advanced perovskite-type materials, such as Lanthanum Strontium Manganite (LSM) and Manganese Cobalt Oxide (MCO) allow production of cathodes and barrier layers with required porosity levels. Also, dense electrolytes can be produced with Yttria Stabilized Zirconia (YSZ) and Gadolinia-Doped Ceria (GDC).

SOFC are often based on a YSZ electrolyte and a lanthanum- and/or strontium-containing cathode material, such as LSM. Electronic conductivity, catalytic activity as well as thermal and chemical compatibility need to be combined with controlled porosity and cost-effective productivity levels.
