HYDROGEN FUEL CELL COOLING

A system for vaporizing hydrogen for providing hydrogen in gaseous form to a plurality of hydrogen fuel cells includes: a vaporizer; a radiator configured to cool a cooling fluid in a coolant system of the plurality of hydrogen fuel cells; a spray supply system comprising: a tank; a pump configured to pump water from the tank; a nozzle system; and a condensate tray configured to collect condensate and return the condensate to the tank. The system is configured to activate the pump to pump the condensate collected in the tank to cool the radiator based on a temperature of the cooling fluid.
