Short-period segmented-in-series solid oxide fuel cells on flattened tube supports

Segmented-in-series solid oxide fuel cells (SIS-SOFCs) were prepared on flattened-tube partially stabilized zirconia supports. The distinguishing characteristic of these cells was the short repeat period, 2.4 mm, and small active cell length, 1.3 mm, compared to ≈10 mm in previous SIS-SOFCs. The support tubes, formed by gelcasting, were bisque fired and then screen printing was used to sequentially deposit Ni-YSZ anodes, YSZ electrolytes, and Pt-YSZ composite interconnects. After high-temperature co-firing, LSM–YSZ and LSM cathode layers were screen printed and fired. Each flattened tube side had 12–16 individual cells. For testing, the open tube ends were sealed and humidified hydrogen flowed inside of the tubes; air was flowed over the outside of the tubes. Maximum total power at 800 °C was ≈8 W and maximum power density was ≈0.7 W cm⁻², calculated using cell active area. Good stability was observed during a ≈650 h steady-state test. Excellent stability was also observed over ≈20 redox cycles.

基于“虚拟匹配”的PCB矩形Mark视觉快速检测

针对机器视觉中PCB(PrintedCircuitBoard,印刷电路板)矩形Mark的检测,提出一种“虚拟匹配”的快速检测方法。根据模板匹配的思想,引入一个“虚拟模板”,通过将虚拟模板内所有像素灰度值的累加和作为是否匹配的衡量标准来进行矩形Mark的检测。借助于粗细搜索的模板移动策略,使得检测过程速度快、精度高、抗噪能力强、对图像缩放可调、对检测图像旋转和光线亮度变化等不敏感,在实际应用中取得了满意的检测效果。
