An actuator incorporating an electrolytic gas generator-evacuator is disclosed. A membrane of material selectively permeable to a drive gas is inserted in a combined inlet-outlet of an expandable chamber. The membrane forms a portion of an electrolytic cell by being immersed in a body of electrolyte capable of transporting an ionic species of the drive gas between the membrane as one electrode and a counter electrode. By connecting the combined inlet-outlet of the chamber to the outside surface of the membrane and cyclically driving the electrolytic cell in a drive gas generation mode and a drive gas evacuation mode, the chamber will cyclically expand and contract.
