  • 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.
