Abstract
An electrochemically actuated pump and an electrochemical actuator for use with a pump. The pump includes one of various stroke volume multiplier configuration with the pressure of a pumping fluid assisting actuation of a driving fluid bellows. The electrochemical actuator has at least one electrode fluidically coupled to the driving fluid chamber of the first pump housing and at least one electrode fluidically coupled to the driving fluid chamber of the second pump housing. Accordingly, the electrochemical actuator selectively pressurized hydrogen gas within a driving fluid chamber.
Claims4
An electrochemical actuator comprising:
- an actuator housing comprising a driving fluid chamber, a bellows, and a pumping fluid chamber;
- one or more electrochemical hydrogen pumps or electrochemical hydrogen pump stacks adjacent to the driving fluid chamber and fluidically coupled to the driving fluid chamber;
- and
- an alkaline/metal hydride electrolyzer adjacent to the one or more electrochemical hydrogen pumps or electrochemical hydrogen pump stacks and is fluidically coupled to the one or more electrochemical hydrogen pumps or electrochemical hydrogen pump stacks opposite the driving fluid chamber, and wherein the alkaline/metal hydride electrolyzer releases hydrogen;
- and
- wherein the one or more electrochemical hydrogen pumps or electrochemical hydrogen pump stacks increase pressure in the driving fluid chamber by moving hydrogen from the alkaline/metal hydride electrolyzer into the bellows in contact with the driving fluid chamber.
