Abstract
A fuel cell system includes a fuel cell, a cooling system fluidly coupled to the fuel cell and having a heat exchanger, a coolant pump, and a coolant reservoir fluidly coupled to the heat exchanger and the coolant pump, a supply system configured to supply a gas containing oxygen to the fuel cell, and a valve positioned in a connecting line between the cooling system and the supply system, the valve operable to limit a pressure difference between pressure of the gas supplied to the fuel cell and pressure within the cooling system.
