Abstract
A method for producing a hydrogen-enriched gas, the method including: (A) generating a mixed gas containing hydrogen and oxygen in a reactor that decomposes water into hydrogen and oxygen using sunlight in the presence of a photocatalyst; (B) collecting the mixed gas in a storage tank; (C) supplying the mixed gas in the storage tank to a gas separation device that includes a membrane having an ability to separate hydrogen and oxygen; and (D) separating a hydrogen-enriched gas from the mixed gas in the gas separation device.
Claims6
A method for producing a hydrogen-enriched gas, the method comprising steps of:
- (A) generating a mixed gas containing hydrogen and oxygen in a reactor that decomposes water into hydrogen and oxygen using sunlight in a presence of a photocatalyst;
- (B) collecting the mixed gas in a first storage tank;
- (C) supplying the mixed gas in the first storage tank to a gas separation device that includes a membrane having an ability to separate hydrogen and oxygen;
- and
- (D) separating a hydrogen-enriched gas from the mixed gas in the gas separation device.
An apparatus for producing a hydrogen-enriched gas, the apparatus comprising:
- a reactor configured to generate a mixed gas containing hydrogen and oxygen through a water decomposition reaction using sunlight in a presence of a photocatalyst;
- a first storage tank configured to collect the mixed gas;
- and
- a gas separation device which includes a membrane having an ability to separate hydrogen and oxygen and to which the mixed gas from the first storage tank is supplied.
