Fundamental experiments for a single-chamber solid oxide fuel cell were conducted. A premixed gas of methane, oxygen, steam and balance nitrogen was supplied to the cellplaced in a rectangular test channel and the exhaust gas compositions and the surface temperature distributions of the electrode were measured. Particular attention was paid to the effects of steam on the various reactions occurring in the cell. It was found that the oxidation of methane prominently proceeded near the upstream edge of the Ni-YSZ cermet followed by steam reforming reactions downstream. An open circuit voltage of 0.9V was achieved at 600oC.

进行了单室固体氧化物燃料电池的基础实验。将甲烷、氧气、蒸汽和余量氮气的预混合气体供应至放置在矩形测试通道中的电池，并测量废气成分和电极的表面温度分布。特别关注蒸汽对电池中发生的各种反应的影响。研究发现，甲烷的氧化在 Ni-YSZ 金属陶瓷的上游边缘附近显着进行，随后在下游发生蒸汽重整反应。在 600oC 时实现了 0.9V 的开路电压。
