Fabrication Methods for Planar Solid Oxide Fuel Cells: A Review

As an environmentally friendly technology, the fuel cell is one of the alternative technologies that can replace fossil fuels. Various types of fuel cells are available in the market, including the solid oxide fuel cell (SOFC). The planar and tubular designs of SOFC are the leading designs mentioned in the literature. Several factors such as manufacturing cost, manufacturing process and production scale differentiate between the two main designs. Each cell component can be produced using a number of methods, two of which are the most common, namely dry pressing and screen printing techniques for the making of planar SOFC. This paper thus reviews several works that have utilized each of the fabricating methods mentioned. The processing steps, technical parameters, and results, such as the maximum power density of each method are discussed.
