To provide a hydrogen production cell of which a thickness per cell is reduced as compared with a conventional one.SOLUTION: A hydrogen side current collector 12 and an oxygen side current collector 13 are arranged on both sides of an electrolyte membrane 11. A separator 14 with a flat surface is arranged outside the hydrogen side current collector 12. A flow passage forming plate 15 and a separator 16 are arranged outside the oxygen side current collector 13. Since a flow passage dedicated for collecting water and a hydrogen gas generated when electrolysis is performed is not formed between the hydrogen side current collector 12 and the separator 16, the thickness of the cell itself can be reduced. These reaction fluids generated during the electrolysis are discharged from the inside of the hydrogen side current collector 12.SELECTED DRAWING: Figure 3
