A temperature sensor and a heating device are provided to prevent moisture from freezing in a direct methanol fuel cell. To achieve this, a secondary battery is connected in parallel to the fuel cell. When the temperature drops to a predetermined level, the secondary battery, using electricity it has stored from the fuel cell, heats a ceramic device. This device is located near the cell, the fuel container or both. When the fuel cell again reaches the desired temperature, it begins normal operations and also charges again the secondary battery. The heating system is prevented from working if a fuel container is not installed in a battery pack or if the battery pack is not connected to an electronic device or if that electronic device is turned off. |
