NOVELTY - Multiple component glass material contains titanium oxide, niobium oxide and/or tungsten oxide. The material has function which discharges dissoluted hydrogen as water vapor molecule by reaction with oxygen in atmosphere. The water molecule is decomposed, and produced hydrogen atom is selectively dissolved. Hydrogen is decomposed, and produced hydrogen atom is dissolved, by increasing partial pressure of hydrogen.    USE - For hydrogen processing to produce hydrogen processed composite material, hydrogen selection film and hydrogen production apparatus (all claimed), such as hydrogen atom sensor, hydrogen molecule sensor, hydrogen separation-and-refinement apparatus and hydrogen storage apparatus.    ADVANTAGE - The multiple component glass material has function which discharges hydrogen. The laminated composite material which consists of the glass material and hydrogen occlusion alloy, is useable in hydrogen processing apparatus by strengthening the hydrogen processing function of the material. The material and the composite material have the function which is dependent on hydrogen concentration in atmosphere, and absorbs or discharges hydrogen reversibly, and hence high hydrogen separation-and-refinement apparatus and hydrogen sensing system of high durability and cost competitiveness are provided by utilizing the material or composite material.    DETAILED DESCRIPTION - Multiple component glass material contains at least one of titanium oxide, niobium oxide and tungsten oxide. The glass material has function which discharges dissoluted hydrogen as water vapor molecule by reaction with oxygen in atmosphere, as reverse reaction. The water molecule is decomposed, and the produced hydrogen atom is selectively dissolved. Hydrogen is decomposed, and the produced hydrogen atom is dissolved, by increasing the partial pressure of hydrogen in atmosphere. The glass material alternately has a function which discharges the dissoluted hydrogen as hydrogen molecule, by reverse reaction. INDEPENDENT CLAIMS are included for the following:    (1) hydrogen processed composite material;    (2) hydrogen selection film; and    (3) hydrogen production apparatus.
