ELECTROLYTIC CELL AND HYDROGEN PRODUCTION APPARATUS

An electrolytic cell includes a housing, a first diaphragm, a first electrode, a second electrode, and a first discharge port. The housing held an electrolyte solution. The first diaphragm partitions the interior of the housing into a first cell and a second cell. The first electrode is provided inside the first cell. The first electrode includes a first surface facing the first diaphragm, a second surface different from the first surface, and a first hole. The second electrode is provided inside the second cell adjacent to the first diaphragm. The second electrode includes a third surface adjacent to the first diaphragm, a fourth surface different from the third surface, and a second hole. The first discharge port discharges the electrolyte solution from the second cell. The first cell is configured to supply the electrolyte solution supplied therein to the third surface side of the second cell.
