GASCHROMIC LIGHT CONTROL MECHANISM

摘要

One aspect of the present invention provides a gaschromic light control mechanism which comprises: a pair of transparent bases that are arranged so as to face each other; a gaschromic light control member that is formed on one or both of the surfaces of the pair of transparent bases, said surfaces facing each other, and that has a light control part the optical characteristics of which are reversibly changed by means of hydrogenation and dehydrogenation; and a hydrogen-air mixed gas supply means that is arranged between the pair of transparent bases and supplies a hydrogen-air mixed gas. The hydrogen-air mixed gas supply means comprises: a mixer which mixes hydrogen and air with each other; an electrolytic cell which comprises a polymer electrolyte membrane and a porous electrode that is provided as a positive electrode on the polymer electrolyte membrane; and an air supply means which supplies air to the mixer and is configured such that the porous electrode is positioned on a flow path of the air.
