Progress in the Design and Fabrication of a Planar Solid Oxide Fuel Cell

The principal technical challenge in the development of the planar solid oxide fuel cell (PSOFC) is the fabrication of the thin cell components and formation of a stacked cell. A single cell planar solid oxide fuel cell system has been fabricated and is being run using hydrogen/steam as a fuel. To achieve higher power outputs, however, a multi-cellular system must be used. In this paper, the design of a stacked planar solid oxide fuel cell system is discussed. The synthesis and fabrication of the cell components; the cathode, the anode, and the interconnect materials, are also discussed.11Nsciescopu
