Abstract
Solid oxide fuel cells (SOFCs) are an interesting choice
for an energy production because of their high
effi-ciency, low emission rate and fuel flexibility.
Metallic interconnect (IC) plates, which separate fuel
and oxidant from each other, act as electrical and
thermal conductors between adjacent cells and give
mechanical support to stack structure. Nevertheless,
metallic IC plates suffer from oxidation and degradation
at SOFC operating temperatures of 600 - 800 °C. Thus,
they need protective coatings, of which the spinel
structured MnCo2O4 has drawn attention recently. It has
been previously deposited by ALD onto small sized R&D
(e.g. 2.5 x 2.5 cm2) substrates. Here we report scaling
up the MnCo2O4 ALD process onto 9 x 9 cm2 ferritic
stainless steel interconnect plates for solid oxide fuel
cells applications. Also the deposition efficiency and
cost estimation for the further scaling up is dis-cussed
in detail
