<p>An electrochemically actuated control valve is disclosed which represents a new class of devices for fluid flow control. The valve is activated by an electrochemical motor which converts DC electrical energy into compressed gas energy suitable for producing mechanical work. The mechanical motion is typically reciprocating linear motion. This linear displacement can be accurately controlled, can be modulated at high frequencies and responds quasi-instantaneously to the applied DC voltage. The electrochemical valve can be computer or microprocessor-controlled.</p>
