FABRICATING SOLID OXIDE FUEL CELLS

摘要

A method for making a solid oxide fuel cell component includes depositing a cathode material directly onto a metallic interconnect. The interconnect may comprise stainless steel or another suitable metal. The cathode material may comprise a ceramic. Examples of cathode materials are yttria-stabilized zirconia (YSZ) and mixtures of YSZ with other ceramics such as lanthanum strontium manganate. The cathode material may be deposited by plasma spraying. A pore former may be plasma sprayed together with the cathode material to provide a porous cathode. Electrolyte and anode materials may be deposited on the cathode material also by plasma spraying. Plasma conditions may be selected to provide a dense electrolyte layer.
