1. A prime mover comprising means defining a gas-tight chamber, an electrolytic membrane disposed in said chamber, said membrane having a first membrane surface and a second membrane surface spaced from said first membrane surface in substantial parallelism thereto, said membrane being fixed within said chamber so as to form at least a first compartment bounded in part by said first membrane surface, a first material-pervious electrode disposed on said first membrane surface and a second material-pervious electrode disposed on said second membrane surface, said first compartment containing an electrochemically active material capable of existing in a gaseous phase and being electrochemically reversibly active so as to enter into a reduction/oxidation reaction at said first and second material-pervious electrodes and produce ions that are transportable through said electrolytic membrane, means connected to said first and second material-pervious electrodes for inducing unidirectional current flow therebetween through said electrolytic membrane so as to ionize said electrochemically active material at one said material-pervious electrode and transport ions through said electrolytic membrane from said second membrane surface to said first compartment thereby effecting a pressure increase in said first compartment, and converting means operatively associated with said first compartment for converting the pressure change therein to mechanical motion.
