Abstract

A single-chamber solid oxide fuel cell (SC-SOFC) with micropatterned electrodes on the electrolyte has been fabricated by a microfluidic lithography technique. Microchannels formed by contacting the polydimethylsiloxane mold with a polished substrate of YSZ disk were filled with the well-dispersed suspensions of the cathode and the anode. The suspensions solidified upon solvent evaporation through the mold, resulting in the SC-SOFC with interdigitated micropatterned electrodes in an area of 5 × 5 mm in which each electrode had 100 μm line width with anode-to-cathode distances of 50 μm. I-V characteristics of the SC-SOFC were analyzed using a dc source meter.
