Title:
FUEL CELL COOLING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/080609
Kind Code:
A1
Abstract:
The present invention relates to a fuel cell cooling method and system, and to a fuel cell cooling method and a fuel cell cooling system to which same is applied, the method comprising: a coolant circulation step of usually repeating a process in which a heat exchanger provided at a main cooling line cools a high-temperature coolant to a low-temperature coolant when the high-temperature coolant is discharged from a fuel cell, thereby suppling same to the fuel cell; a thermal load monitoring step of monitoring thermal load changes in the fuel cell; and a cooling line switching step of switching a cooling line from the main cooling line to an auxiliary cooling line including an auxiliary coolant tank so that, if the thermal load of the fuel cell sharply increases to be greater than usual, a low-temperature coolant stored in the auxiliary coolant tank is supplied to the fuel cell before the low-temperature coolant supplied from the heat exchanger to the fuel cell.
