1. An electrochemical cell, comprising a housing comprising one or more fluid inlet apertures, a negative electrode, a fluid consuming positive electrode, and a microvalve assembly operatively connected to the one or more fluid inlet apertures for controlling passage of fluid to the fluid consuming positive electrode, wherein the microvalve assembly comprises;

  • (a) a stationary microvalve body comprising an aperture located between a first surface and a second surface;

    (b) a movable microactuator connected to the microvalve body and capable of moving between a first position where fluid cannot pass through the microvalve body aperture and a second position which allows fluid to pass through the microvalve body aperture; and

    (c) a latch, operatively connected to the microvalve body, the latch comprising a moveable latch component that changes shape upon application of a potential across the moveable latch component.
