|A Novel Design of a Planar SOFC with the Anode Supported on the Base Ceramic Structure|
|Keywords: Solid Oxide Fuel Cell, microchannels, supported anode|
|The novel design of a planar SOFC enables to support the anode layer on a base ceramic structure with engraved microchannels of width 250 microns. According to this design, the supporting beams of the microchannels made with the same material as the anode and well bonded to the anode by co-firing increase the mechanical endurance of the anode layer. The anode layer is 100 microns thick. Other functional layers such as electrolyte and cathode layers are deposited further by screen printing and fired separately. The base ceramic structure is equipped also in fuel distributors and manifolds. Fuel, that flows through microchannels just underneath the surface of the anode, has an easy access to the working part of the anode. Commercially available nickel/zirconia cermet (Ni/YSZ) was used for the anode and the base ceramic structure, yttria stabilised zirconia (YSZ) for the electrolyte and lanthanium strontium manganite (LSM) for the cathode. The flat base structure of SOFC simplifies processing of SOFC. Deposition of the electrolyte and the cathode layers can be completed exclusively with screen printing. Proposed new structure of SOFC is convenient for assembly into batteries, and additionally each cell can be tested separately prior assembly. The paper presents the method of processing of a planar ceramic SOFC and reveals the results of measurements of basic electrical parameters. It discusses trade-offs of the new design and suggests its further possible improvements.|
