ABSTRACT:
A fluid consuming battery (10) is provided with a fluid regulating system (50) for regulating fluid entry into the battery. The battery (10) includes a fluid consuming cell (20) having a cell housing with fluid entry ports for the passage of a fluid into the cell housing. A first fluid consuming electrode and a second electrode are disposed within the cell housing. The fluid regulating system (50) includes a valve having a moving plate (66) disposed adjacent to a fixed plate (62). The moving plate and fixed plate both have fluid entry ports (68, 64) that align in an open valve position and are misaligned in a closed valve position. The fluid regulating system (50) also includes an actuator that may include one or more shape memory alloy (SMA) components (82a,82b) for moving the moving plate (66) relative to the fixed plate (62) to open and close the valve.
