More Information
Summary:A mechanical valve for adjusting coolant flow which may be opened and closed based on the pressure of a coolant and a fuel cell cooling system using the same are provided. The valve has a mechanical valve structure to be opened and closed by the pressure of a coolant introduced into a coolant inlet and thus blocks and permits the coolant circulated to an ion filter line during operation of a fuel cell stack at the maximum output. The valve performs a coolant flow blocking function executed by a conventional electronic valve and thus a fuel cell cooling system has a simplified structure using the valve.
