The present disclosure relates to a thermal management system and method of adjusting and/or reversing coolant flow of a fuel cell system during stationary applications.

The present disclosure relates to a thermal management system and method of adjusting and/or reversing coolant flow of a fuel cell system during stationary applications.

A fuel cell cooling system mounted on a vehicle includes a flow path for a coolant; a cooling unit that cools the coolant in a cooling unit flow path; a fuel cell to be cooled through heat exchange with the coolant in a fuel cell flow path; a heat generating body to be cooled through heat exchange with the coolant in a heat generating body flow path; first and second pumps that pump the coolant in the fuel cell and heat generating body flow paths, respectively; and a control circuit. When the vehicle is started, the control circuit performs a first process of actuating the first pump with the second pump stopped, and a second process of actuating the first and second pumps when the temperature of the coolant in the fuel cell or cooling unit flow path exceeds a first reference value during the first process.

The present disclosure relates to a boil-off gas treatment system and method for a fuel cell electric vehicle, and a main object of the present disclosure is to provide a boil-off gas treatment system and method capable of safely and efficiently treating, storing, and utilizing vaporized hydrogen in a hydrogen tank for a fuel cell electric vehicle.

A method and system of controlling hydrogen purge are provided. The method includes estimating an air supply rate supplied to a fuel cell stack and then executing hydrogen purge based on the estimated air supply rate.

The cooling system includes an energy source, one or more heat exchangers for cooling a coolant, the one or more heat exchangers being connected to the energy source by a coolant circuit, one or more air channels inside which the one or more heat exchangers are placed, wherein the coolant circuit includes a bypass portion that recirculates the coolant to the energy source or circulates the coolant from the energy source to the one or more heat exchangers. The method includes decreasing the temperature of a portion of a coolant below an operating temperature, acting this portion of the coolant as a thermal buffer, and maintaining the rest of the coolant at the operation temperature. They allow enhancing the cooling capabilities of the system during the take-off phase, especially during the beginning of this phase.
