Abstract
Abstract A light driven hydrogen oxygen generator in which a hydrogel coating is polymerized over photoreceptors allowing the electrolyte to reach the surface of the photoreceptor and protect the photoreceptor from contamination by impurities which may be present in the electrolyte. The surface of the hydrogel also rejects the accumulation of debris to maintain its permeability.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
45 words
A light driven hydrogen and oxygen generator having a plurality of light absorbing semiconductor receptors imbedded within a hydrogel, said light receptors being capable of producing an electrical current when activated by light, and providing hydrogen and oxygen by the decomposition of water by electrolysis.
Claim 2
Dependent Claim
45 words
A light driven hydrogen and oxygen generator having a plurality of light absorbing semiconductor receptors imbedded within a hydrogel, said light receptors being capable of producing an electrical current when activated by light, and providing hydrogen and oxygen by the decomposition of water by electrolysis.
Claim 3
Dependent Claim
47 words
A light powered hydrogen and oxygen generator composed of a transparent hydrogel having light absorbing semiconductor receptors imbedded within the hydrogel, said light receptors being capable of producing an electrical current when energized by light and providing hydrogen and oxygen by the decomposition of water by electrolysis.
Claim 4
Dependent Claim
47 words
A light powered hydrogen and oxygen generator composed of a transparent hydrogel having light absorbing semiconductor receptors imbedded within the hydrogel, said light receptors being capable of producing an electrical current when energized by light and providing hydrogen and oxygen by the decomposition of water by electrolysis.
Claim 5
Dependent Claim
34 words
A hydrogen and oxygen generator having light receptors imbedded in a protective hydrogel whereby impurities and debris which may be present outside the hydrogel do not come in contact with the protected light receptors.
Claim 6
Dependent Claim
34 words
A hydrogen and oxygen generator having light receptors imbedded in a protective hydrogel whereby impurities and debris which may be present outside the hydrogel do not come in contact with the protected light receptors.
