The container is sealed during non-use. When a power switch is turned on, the air inlet and air outlet are opened. At the same time, the residual low power of the battery cells is used to start a fan positioned near the air inlet. The fan initiates an air flow across the battery cells to further increase the power supply output. The power supply output is limited to the use requirement of the device by varying the fan speed in response to instructions from the device. Precise control of the battery cells' exposure to air extends the lifetimes of the cells.Field of SearchFUEL CELL, SUBCOMBINATION THEREOF OR METHODS OF OPERATINGAutomatic control means Electrical output dependent Active material electrode-type cell or subcombination thereof Housing member, seal, spacer or fluid distributing or directing means Activation of inactive cell WITH CONTROL MEANS RESPONSIVE TO BATTERY CONDITION SENSING MEANS DEFERRED ACTION TYPE Process of operating |
