  • Publication number: 20120115059
    Abstract: An electricity output managing system for a fuel cell stack is disclosed. It includes a fuel cell stack, many power switches, an electricity adjusting module, multiple thermal sensors, and a controller. This electricity adjusting module is provided to combine the electricity outputs from these power switches into a single final output. The thermal sensors can detect the inner temperature values of the fuel cell units. The controller can receive the inner temperature values via these thermal sensors and calculate an average of all the inner temperature values which is a floating one. When one of the inner temperature values falls outside a normal range or one of the inner temperature value's variation rates exceeding a preset reference value, the controller turns off the power switch of the corresponding fuel cell unit and sends out a warning signal. So, it can effectuate the fuel cell management by monitoring the inner temperatures of these fuel cell units.
