Abstract
Segmented-in-series solid oxide fuel cell (SOFC) arrays typically feature cell widths ≥1 cm. We consider here the advantages and disadvantages of decreasing the cell width to 1–2 mm. The calculation results indicate that electrode resistance losses can be minimized via reduced widths, even for relatively thin electrodes. Initial results are presented for screen printed arrays, with 1-2 mm wide individual cells, on porous partially stabilized zirconia supports. The cells consisted of Ni-YSZ anodes, YSZ electrolytes, and cathodes. Au or Pt interconnects were used for this initial demonstration. © 2004 The Electrochemical Society. All rights reserved.
