采用微流控光刻技术制作了一种在电解质上具有微图形电极的单室固体氧化物燃料电池（SC-SOFC）。通过将聚二甲基硅氧烷模具与抛光的YSZ盘基底接触而形成的微通道填充有分散良好的阴极和阳极悬浮液。悬浮液在溶剂蒸发通过模具时固化，得到具有5 X 5 mm面积的交叉指型微图案化电极的SC-SOFC，其中每个电极具有100 μ π ι线宽，阳极到阴极距离为50 μ π ι。利用直流源表对SC-SOFC的I-V特性进行了分析。
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 X 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.
