Abstract: <P>PROBLEM TO BE SOLVED: To provide a gas sensor device capable of greatly improving gas species discrimination ability by enabling to acquire a larger peak value relative to a gas having strong adsorbability.  <P>SOLUTION: A Peltier element 50 as a prescribed cooling element is arranged under a catalytic combustion gas sensor 40, and controlled so that the catalytic combustion gas sensor 40 is cooled at a fixed temperature. A specific gas is discriminated based on a sensor output when a prescribed driving pulse is applied to the catalytic combustion gas sensor 40. Namely, the adsorbability is greatly improved by cooling the catalytic gas sensor 40 at the fixed temperature. When the adsorbability is improved, many gas molecules are adsorbed during the off-time in intermittent driving. Consequently, since many adsorbed molecules are burned at the on-time initial stage, a sensor output having a large peak value can be acquired.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
