NOVELTY - A battery (10) comprises fluid regulating system (50) comprising valve for adjusting rate of passage of fluid to fluid consuming electrode, and actuator for operating valve, and comprising first and shape memory alloy components for opening and closing valve, respectively, where first shape memory alloy component actuates valve at first temperature ( greater than or equal to 90 degrees C) to open valve and second shape memory alloy component actuates valve at second temperature ( greater than or equal to 45, preferably 60 degrees C) to close valve.    USE - A battery, e.g. air-depolarized or air assisted battery.    ADVANTAGE - The battery has high temperature fluid regulating shutoff valve that responds to changes in a potential applied across the actuator to open and close the valve.    DETAILED DESCRIPTION - A battery (10) comprises fluid consuming cell(s) comprising a cell housing comprising fluid entry port(s) for the passage of a fluid into the cell, a first fluid consuming electrode disposed within the cell housing, and a second electrode disposed within the cell housing; and a fluid regulating system (50) comprising a valve for adjusting the rate of passage of the fluid to the fluid consuming electrode, and an actuator for operating the valve. The actuator comprises a first shape memory alloy component for opening the valve and a second shape memory alloy component for closing the valve where the first shape memory alloy component actuates the valve at a first temperature ( greater than or equal to 90 degrees C) to open the valve and the second shape memory alloy component actuates the valve at a second temperature ( greater than or equal to 45, preferably 60 degrees C) to close the valve, and where the second temperature is lower than the first temperature so that the second shape memory alloy component closes the valve upon reaching the second temperature. An INDEPENDENT CLAIM is included for a fluid regulating system.    DESCRIPTION OF DRAWING(S) - The drawing is an exploded perspective view of a battery bottom along with the components forming a fluid regulating system used with the battery.
