A cooling system for a fuel cell onboard a vehicle includes a coolant circuit and an auxiliary evaporative cooler. The coolant circuit is configured to circulate a coolant including a phase change material therethrough and through a portion of the fuel cell to absorb heat from the fuel cell. The auxiliary evaporative cooler includes a coolant channel in fluid communication with the coolant circuit, an airflow channel in fluid communication with an ambient environment, and a selectively permeable membrane that physically separates the coolant channel from the airflow channel and is selectively permeable to the phase change material. The auxiliary evaporative cooler is configured to evaporatively cool the coolant flowing through the coolant channel by promoting evaporation and transport of the phase change material from the coolant flowing through the coolant channel, through the selectively permeable membrane, and into an ambient airflow flowing through the airflow channel.
