Abstract

An electrochemically operable actuator (20), includes a support structure, a flexible membrane sealed against the support structure to form a compartment (108), electrochemical element (101) adapted to generate hydrogen or oxygen gas and to deliver the gas to the inside of the compartment, the electrochemical element including an ion conducting membrane having an electrode on opposing sides thereof, and terminal element for connecting a voltage source to enable applying a potential across the electrodes. The electrochemical element can be a hydrogen pump (101) or an electrolyzer or both. A fuel cell assembly (100) incorporating a valve (V) with an actuator is also described.
