Abstract
A cooling system and cooling method for a fuel cell onboard a vehicle, wherein the fuel cell includes a gasifier configured to expand liquid hydrogen to gaseous hydrogen for feed to the fuel cell, the cooling system including a coolant system sized for less than peak power operation of the vehicle; and an auxiliary coolant system configured to provide supplemental cooling to the fuel cell, wherein the supplemental coolant system is configured to by-pass coolant to the gasifier and employ heat of gasification of the liquid hydrogen to provide supplemental cooling for the fuel cell during peak vehicle operation.
