Observation of produced water on monolithically fabricated miniature fuel cell

展示了在燃料通道底部上的产出水的观察。发现性能差的电池在燃料电池芯片内部显示出水产生的显著变化。一些观察表明，通道底部和催化剂层之间的残留多孔Si通过阻塞燃料供应而对电池性能产生不良影响。尝试去除残留的多孔硅，并且通过消除残留的多孔硅证明了更高的性能。

Observation of produced water on a fuel channel bottom was demonstrated. It was found that poor performance cell showed significant variation of water production inside the fuel cell chip. Some observations suggested that the residual porous Si between the channel bottom and the catalyst layer had bad impact on the cell performance by blocking fuel supply. Removal of the residual porous Si was attempted and higher performance was demonstrated by the elimination of the residual porous Si.
