<p>An energy management system controls the temperature of a fuel cell system while a vehicle is not running. The energy management system includes a fuel cell stack (108), a blower (110) that provides air to the fuel cell stack, a water supply (150), and a hydrogen supply (120). A hydrogen supply valve (128) is connected between the hydrogen supply and the fuel cell stack. A heater (136) is connected to an output of the fuel cell stack. A controller (160) controls the hydrogen supply valve and the blower to power the heater to warm the fuel cell stack and the water supply. The controller starts the blower and opens the hydrogen supply valve if heating is necessary and if the tank level signal exceeds a first tank level value. The controller activates a purge, drains water from the water supply, and inhibits vehicle startup if the tank level signal does not exceed a first tank level value.</p> |
