Electrochemical prime mover
First Claim
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.

Abstract
A prime mover or motor having one or more compartments in which pressure variations are produced by transporting molecules into and/or out of the compartment by means of an electrolytic membrane. Devices for converting the pressure changes to mechanical motion without adversely affecting the sealed condition of the compartment. The mechanical motion produced by the apparatus of the invention is typically reciprocating linear motion and means are disclosed for converting such motion into a pumping function, a rocking function or a rotating function. Disposed within the compartments is an electrochemically active material that can exist in the gaseous phase and that can enter into an oxidation/reduction reaction in order to form ions that move across an electrolytic membrane so as to increase or decrease pressure in a compartment in response to application of a voltage gradient of proper duration and polarity across the membrane. Hydrogen and oxygen are materials for use in the apparatus.
