Fuel cell vehicle thermal system

Abstract

A thermal management system for a vehicle having a fuel cell stack includes a condenser fluidly coupled to the fuel cell stack to receive a flow of water/air exhaust therefrom, and a liquid-gas separator fluidly coupled to the condenser to receive the flow of water/air exhaust therefrom, the liquid-gas separator including a first outlet to direct separated gas to an exhaust line, and a second outlet for separated liquid water. The spray nozzles are fluidly coupled to the separator second outlet to receive a flow of liquid water therefrom, and a coolant circuit is configured to circulate a coolant to the fuel cell stack for cooling thereof, the coolant circuit including a radiator configured to cool the coolant. The one or more spray nozzles are configured to selectively spray the liquid water onto the radiator to increase cooling of the coolant and improve performance of the fuel cell stack.
