| 摘要 |
The invention relates to a photochemical cell (1) and to a method for the solar-driven decomposition of a starting material, in particular water or carbon dioxide, into a product gas bound therein, in particular hydrogen or carbon monoxide, comprising a supply line (7) for the starting material, a discharge line (9) for the obtained product gas, a first electrode (2) made of a photoelectrically active material and exposed to solar radiation (3′, 3″) during operation, and a second electrode (5), wherein the electrodes (2, 5) are connected to each other in a closed circuit by means of an electron conductor (4) for transporting electrons excited by the solar radiation (3′, 3″) in the first electrode (2) and an ion conductor (6) for transporting ions produced in the decomposition of the starting material, wherein an electrolyte made of a heat-resistant solid material and arranged between the electrodes (2, 5) is provided as the ion conductor (6). |
