Systems and methods to utilize water output of fuel cell systems for evaporative cooling of radiators

A method of dissipating heat in a system comprising:

• passing a coolant used in a fuel cell system through a radiator,
• dissipating heat produced by the fuel cell system by using water output from the fuel cell system,
• evaporating the water output from the fuel cell system,
• operating at least one fan arranged adjacent the radiator to direct air flow toward the radiator,
• cooling the radiator by the evaporated water output from the fuel cell system to produce an evaporative cooling effect, and
• using a controller that comprises a look ahead power estimator, a fuel cell liquid water estimator, and an evaporative cooling benefit to determine when to create the evaporative cooling effect.
