Abstract

PURPOSE: To easily detect hydrogen gas, by using Pd-Sn-SnO2 group material.
CONSTITUTION: PdCl2 (1wt%), Mg(NO3)2 (1wt%) and Rh (6wt%) are mixed with SnO2 and said mixture is crushed after precalcining at 800°C for one hour and paste is made by dispersing the obtained powder in alcohol uniformly. Then, said paste is applied on the Al2O3 substrate which has been printed Pt-Au electrode and is calcined at 100°C for one hour. Hereby, the terminal voltage of element is set at 40V and output voltage of detected resistance connected with the element in series is set at 4V and then, the output voltage after contact of gas is read. The temperature of the element is 97°C and is lower than the normal element and then, the oscillation frequency is high and also, the oscillation phenomenon in H2 gas is observed. Thus, expected purpose can be attained.
