Abstract
A hydrogen generation electrode is used for an artificial photosynthesis module that decomposes an electrolytic aqueous solution into hydrogen and oxygen with light. The hydrogen generation electrode has a conductive layer, an inorganic semiconductor layer that is provided on the conductive layer and has a pn junction, and a functional layer that covers an inorganic semiconductor layer. The steam permeability of the functional layer is 5 g/(m·day) or less.
