Abstract
A fuel cell system and a method of controlling the fuel cell system is provided. A fuel cell generates power, and a coolant system provides coolant flow through the stack. A controller is configured to, in response to at least one of an ambient temperature and a coolant temperature being below a threshold value after a vehicle shut down command or event, command the coolant system to circulate coolant through the stack to reduce ice formation in the stack prior to commanding a purge of the fuel cell stack.
