With the coming use of hydrogen-driven vehicles, a highly sensitive and selective hydrogen sensor was required aiming at application like fire warning or leakage-control system.

A novel gas sensitive element for detecting environmental CO 2 was developed.

In the present paper by the dynamic pulse measurent of gas sensitive element the formulae of calcuting the concentration value of gas reaching surface are obtained by Gass Funtion,and the vapour pressure is modified while measuring the vapour above the liquid regent.
