ELECTROCHEMICAL REDUCTION DEVICE

摘要

This electrochemical reduction device (10) is provided with an electrode unit (100), a power controller (20), an organic-material storage tank (30), a water storage tank (40), a steam separator (50), and a controller (60). The electrode unit (100) comprises an electrolyte membrane (110), a reducing electrode (120), and an oxygen-generating electrode (130). The oxygen-generating electrode (130) has the following: an electron-conducting metal substrate; a protective layer that covers said metal substrate and contains at least one metal or metal oxide selected from among niobium (oxides), molybdenum (oxides), tantalum (oxide), and tungsten (oxides); and a catalyst that is supported on the surface of the protective layer and contains at least one metal or metal oxide selected from among ruthenium (oxides), rhodium (oxides), palladium (oxide), iridium (oxide), and platinum (oxides).
