  • Hydrogen sensor, hydrogen detecting system and method
    Patent number: 8409869
    Abstract: A hydrogen sensor comprises a substrate having a surface coated with a hydrogen absorbing material and a temperature sensitive luminophore such that when the temperature sensitive luminophore is excited, it generates a fluorescent light, the luminescence of which is changed by an exothermic heat resulting from the adsorption of hydrogen through the hydrogen absorbing material. A hydrogen detecting system and a method of detecting hydrogen using the hydrogen sensor are also disclosed.
