Thermal management system of fuel cell, fuel cell system, and vehicle with the fuel cell system

Abstract

The invention provides a thermal management system of a fuel cell, a fuel cell system and a vehicle with the fuel cell system. The thermal management system of the fuel cell according to the invention comprises a cooling system for recovering waste heat produced by the fuel cell system, and a heating system that is in communication with the cooling system and performs heating by the waste heat recovered by the cooling system. The fuel cell system according to the invention comprises a fuel cell stack, and further comprises the thermal management system of the fuel cell. According to the thermal management system of the fuel cell, the fuel cell system and the vehicle with the fuel cell system provided by the invention, the thermal management system of the fuel cell can cool each component of the fuel cell system by the cooling system and recover the waste heat produced by the fuel cell system; the waste heat recovered by the cooling system serves as the heat source for heating by the heating system, therefore, the heat produced by the fuel cell stack and tail gas as well as the heat produced by accessories such as electric accessories during fuel cell stack operation can be effectively utilized, and the cost of operating the fuel cell can be reduced.

Description

technical field [0001] The invention relates to the field of heat dissipation of fuel cells for vehicles, in particular to a fuel cell thermal management system, a fuel cell system and a vehicle with the system. Background technique [0002] Fuel cell vehicles drive the vehicle through the electric energy generated by the electrochemical reaction of the fuel cell. Because of its high efficiency, zero emissions, stable operation, and no noise, it is called "authentic environmental protection vehicle" and is the future vehicle. The trend of industrial development. The core component of a fuel cell vehicle is a fuel cell stack. A fuel cell is an efficient, clean, and sustainable power generation device. Taking a proton exchange membrane fuel cell (PEMFC) as an example, fuel gas (hydrogen or reformed hydrogen) from the anode Side entry, hydrogen atoms lose electrons at the anode and become protons, protons pass through the proton exchange membrane to the cathode, and electrons ...
