Abstract:
1. A hydrogen production device comprising: a translucent substrate; a photoelectric conversion part having a light acceptance surface and a back surface, and provided on the translucent substrate; a first gas generation part provided on the back surface; a second gas generation part provided on the back surface; a plate provided over the first gas generation part and the second gas generation part so as to be opposed to the substrate; a space is provided between each of the first gas generation part and the second gas generation part, and the plate; and a partition wall to separate a space between the first gas generation part and the plate and a space between the second gas generation part and the plate, wherein one of the first gas generation part and the second gas generation part is a hydrogen generation part to generate H the first gas generation part is electrically connected to the back surface, and the second gas generation part is electrically connected to the light acceptance surface via a first conductive part, and the space between the first gas generation part and the plate and the space between the second gas generation part and the plate were connected so that the electrolytic solution flows between the spaces.
