Abstract
A fuel cell system and method for operating a fuel cell system have a water separator for extracting water contained in a fuel cell exhaust stream. The method comprises varying the pressure of the fuel cell exhaust stream in response to a change in ambient temperature in the vicinity of the fuel cell system. The pressure can be varied by the use of a flow control device positioned downstream of the fuel cell and operationally linked to an ambient temperature sensor.
