A vehicle includes a fuel cell system, and a controller configured to receive a first signal indicative of a predicted ambient temperature at a specified location, and command the fuel cell system to operate at a reduced relative humidity when the predicted ambient temperature is below a threshold value. A method for controlling a fuel cell system includes receiving a first signal at a controller indicative of a predicted ambient temperature for a specified location, and operating the fuel cell system at a reduced relative humidity when the predicted ambient temperature is below a threshold value. A fuel cell system includes a fuel cell stack, and a controller configured to, in response to receiving a predicted freezing condition, command the fuel cell stack to operate at a lower relative humidity level for a time period preceding a predicted time for system shut down.
