GAS SENSOR AND FUEL CELL VEHICLE

WIPO Patent Application WO/2017/037984

A1

This gas sensor detects gas molecules that include hydrogen atoms contained in a gas, the gas sensor characterized in comprising: a first electrode having a first principal surface, and a second principal surface on the opposite side of the first principal surface; a second electrode having a third principal surface facing the second principal surface of the first electrode, and a fourth principal surface on the opposite side of the third principal surface; a metal oxide layer disposed between the first electrode and the second electrode and in contact with the second principal surface of the first electrode and the third principal surface of the second electrode; and an insulating film for covering at least a portion of the first electrode, and at least a portion of the second electrode and a portion of metal oxide layer, at least a portion of the fourth principal surface of the second electrode being exposed to gas without being covered by the insulating film, and the metal oxide layer having a reduced resistance value by the second electrode being in contact with the gas molecules.
