| Research Abstract |
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.
