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 La_0.6Sr_0.4Fe_0.8Co_0.2O ₃-based cathodes. Au or Pt interconnects were used for this initial demonstration.
