PURPOSE: To develop an actuator which stores hydrogen formed by electrolysis of water using a hydrogen occlusion metal electrode having an internal space in a high-pressure state in the spacing in the electrode and is actuated by utilizing a gaseous hydrogen pressure. CONSTITUTION: The cathode 1 made of the hydrogen occlusion metal (alloy) and an anode 2 as a counter electrode consisting of Pt, etc., are immersed into an electrolyte 3 consisting of light water or heavy water in an electrolytic cell 4. A bulkhead 5 consisting of rubber, Ti, Mo steel, etc., having elasticity is mounted at the hydrogen occlusion metal 1 of a cathode to form the internal space 6 between the bulkhead and the cathode 1. Voltage is impressed on the cathode 1 and the anode 2 by a power source 7 and the gaseous hydrogen or deuterium generated at the cathode 1 by the electrolytic effect is absorbed into the cathode 1 of the hydrogen occlusion metal and is filled under a high pressure into the internal space 6 formed of the elastic bulkhead 5. This high-pressure gaseous hydrogen (deuterium) is taken out of an operating section 8 and the actuator is actuated by the pressure thereof. In such a case, the gaseous hydrogen is controllable by the magnitude of the impressed voltage and conversely, actuator may be actuated by reversing the plus and minus of the electrolysis to discharge the hydrogen in the space and to generate a negative pressure as an attracting force. |
