A cooling system for a fuel cell onboard a vehicle includes a plenum, a coolant circuit, and a liquid-to-air heat exchanger. The plenum is configured to receive an airflow from an ambient environment. The coolant circuit is configured to circulate a coolant through the coolant circuit and through a portion of the fuel cell. The liquid-to-air heat exchanger includes a thermally conductive wall having a first side that at least partially defines an airflow channel in fluid communication with the plenum and an opposite second side that at least partially defines a coolant channel in fluid communication with the coolant circuit. The first side of the thermally conductive wall includes a porous wick. When a working fluid is introduced into the porous wick, the porous wick is configured to evaporatively cool the coolant flowing through the coolant channel by promoting evaporation of the working fluid therefrom.
