Abstract
Metal-supported SOFCs with power densities above 700 mW/cm2 at 750oC
were fabricated by atmospheric plasma spraying, which can be readily automated
and scaled for larger cell areas and production volumes, with no cell sintering
requirement. Porous stainless steel substrates were dip-coated to protect
against oxidation and chromium loss, followed by fabrication of the functional
layers.
Preliminary performance
in hydrogen was found to be stable for 200 hours, with longer durability tests
ongoing. Cells with modified anodes can achieve performances close to those of
standard cells operating in hydrogen, with no evidence of coking in TGA methane
experiments. Fabrication of anodes for hydrocarbon fuels and the results of
scaling up from button cells to 5cm x 5cm cells are discussed.
