Abstract
A water spray cooling system includes a first storage container storing exhaust water generated from a fuel cell system comprised in the fuel cell electric vehicle, a second storage container connected to the first storage container via a first valve; a first tube connecting a first opening of the second storage container with an air tank via a second valve. The air tank comprises compressed air generated from a compressed air system comprised in the fuel cell electric vehicle. The cooling system also includes one or more water spray nozzles connected to a second opening of the second storage container through a second tube.

A water spray cooling system for a fuel cell electric vehicle, wherein the cooling system comprises:
- a first storage container configured to store exhaust water generated from a fuel cell system comprised in the fuel cell electric vehicle;
- characterized in that the cooling system further comprises:
- a second storage container connected to the first storage container via a first valve;
- a first tube connecting a first opening of the second storage container with an air tank via a second valve, wherein the air tank comprises compressed air generated from a compressed air system comprised in the fuel cell electric vehicle;
- and
- one or more water spray nozzles connected to a second opening of the second storage container through a second tube;
- and wherein
- the first and second valves are configured to be controlled during a water spray event such that the first valve is first open to fill water from the first storage container to the second storage container and then closed, and after the first valve is closed, the second valve is open to deliver the compressed air from the air tank to the second storage container to create a water spray at the water spray nozzle.
A cooling method for a fuel cell electric vehicle comprising:
- providing a first storage container configured to store exhaust water generated from a fuel cell system comprised in the fuel cell electric vehicle;
- providing a second storage container connected to the first storage container via a first valve;
- providing a first tube connecting a first opening of the second storage container with an air tank via a second valve, wherein the air tank comprises compressed air generated from a compressed air system comprised in the fuel cell electric vehicle;
- providing one or more water spray nozzles connected to a second opening of the second storage container through a second tube;
- controlling the first and second valves during a water spray event such that the first valve is first open to fill water from the first storage container to the second storage container and then closed, and after the first valve is closed, the second valve is open to deliver the compressed air from the air tank to the second storage container to create a water spray at the water spray nozzle.
