Abstract :
The characteristics of an optical hydrogen sensor based on tungsten oxide film are studied. It is shown, that on velocity of initial change of light transmission of sensor in H2-air mixture it is possible to define concentration H2 rapidly. The mean of rapidly periodic decoloration of an optical sensor by transient activation of WO3/Pt film in contact with electrolyte is offered.
