PROBLEM TO BE SOLVED: To provide an electricity generating device securing the safety of user's handling. SOLUTION: The electricity generating device comprises a hydrogen cartridge 3 housing a hydrogen occlusion material 32 insides, an electricity generating part 8 generating electricity by using the hydrogen gas supplied from the hydrogen cartridge 3, and a check valve 5 preventing the gas, flowing from the electricity generating part 8 to the hydrogen cartridge 3, from back flow. By the above, the hydrogen gas remaining at the electricity generating part 8 does not back flow and not released into the air even if the hydrogen cartridge 3 is removed from the electricity generating part 8. |
