摘要： The present invention relates to a nitrogen oxide detecting element. Although there has been a demand for effecting detection of a nitrogen oxide by using a semiconductor type gas sensor, no semiconductor type sensors have existed which can detect the nitrogen oxide with good selectivity against other interfering gases (CO, H2) for an extended period of time with good durability. Then, by causing a gas detecting portion to include an oxide containing more than a predetermined amount of Bi and maintaining this gas detecting portion at a temperature range where its electron-conductivity is exhibited, it has become possible to detect the nitrogen oxide.

摘要： A fuel cell system includes: a fuel cell stack that is formed of a plurality of serially connected fuel-cell cells that use fuel gas and oxidant gas to generate electric power; a detecting unit that detects an output power generated by each of a first fuel-cell cell group and a second fuel-cell cell group that are grouped on the basis of a power generation performance factor; and an operating condition changing unit that changes an operating condition of the fuel-cell cells on the basis of a rate of deviation between the generated output power of the first fuel-cell cell group, detected by the detecting unit, and the generated output power of the second fuel-cell cell group, detected by the detecting unit.
