    摘要： A photoelectrochemical cell (100) includes: a semiconductor electrode (120) including a substrate (121), a first n-type semiconductor layer (122) disposed on the substrate (121), and a second n-type semiconductor layer (123) and a conductor (124) disposed apart from each other on the first n-type semiconductor layer (122); a counter electrode (130) connected electrically to the conductor (124); an electrolyte (140) in contact with surfaces of the second n-type semiconductor layer (123) and the counter electrode (130); and a container (110) accommodating the semiconductor electrode (120), the counter electrode (130) and the electrolyte (140). In the semiconductor electrode (120), relative to a vacuum level, (I) band edge levels of a conduction band and a valence band in the second n-type semiconductor layer (123), respectively, are higher than band edge levels of a conduction band and a valence band in the first n-type semiconductor layer (122), (II) a Fermi level of the first n-type semiconductor layer (122) is higher than a Fermi level of the second n-type semiconductor layer (123), and (III) a Fermi level of the conductor (124) is higher than the Fermi level of the first n-type semiconductor layer (122). The photoelectrochemical cell (100) generates hydrogen by irradiation of the second n-type semiconductor layer (123) with light.

    摘要： This invention is an apparatus and a method for continuously generating a hydride gas of M1 which is substantially free of oxygen in a divided electrochemical cell. An impermeable partition or a combination of an impermeable partition and a porous diaphragm can be used to divide the electrochemical cell. The divided electrochemical cell has an anode chamber and a cathode chamber, wherein the cathode chamber has a cathode comprising M1, the anode chamber has an anode comprising M2 and is capable of generating oxygen, an aqueous electrolyte solution comprising a hydroxide M3OH partially filling the divided electrochemical cell. Hydride gas generated in the cathode chamber and oxygen generated in the anode chamber are removed through independent outlets. M1 can be selenium, phosphorous, silicon, metal or metal alloy, M2 is metal or metal alloy suitable for anonic oxygen generation, and M3 is NH4 or an alkali or alkaline earth metal.
