Abstract

The invention discloses a hydrogen fuel cell thermal management system, which comprises a gas inlet cooling heat exchanger, a first refrigerant pump, a first refrigerant liquid storage tank and a fuel heat exchanger, and is characterized in that a cathode gas flow path and a first refrigerant heat absorption flow path are formed in the gas inlet cooling heat exchanger; a fuel flow path and a first refrigerant heat release flow path are formed in the fuel heat exchanger, and the first refrigerant liquid storage tank, the first refrigerant pump, the air inlet cooling heat exchanger and the fuel heat exchanger are sequentially communicated to form a first refrigerant circulation loop. According to the invention, the technical problems that the cooling structure of the fuel cell is relatively complex and the system energy efficiency is not high are effectively solved.

Description

technical field [0001] The invention relates to the field of fuel cell hydrogen energy vehicles, in particular to a hydrogen fuel cell thermal management system. Background technique [0002] The working principle of the hydrogen energy vehicle is that the hydrogen in the hydrogen storage device of the hydrogen energy vehicle is introduced into the electric stack of the fuel cell of the hydrogen energy vehicle, and then reacts with the oxygen in the air to generate electric energy to drive the energy vehicle. When a hydrogen fuel cell engine is matched with a liquid hydrogen or high-pressure hydrogen system, the liquid hydrogen or high-pressure hydrogen needs to be decompressed, vaporized, or heated to about 50°C before entering the fuel cell stack. This process requires a lot of heat absorption. Fuel cell stacks will generate a lot of waste heat during operation, and coolant is usually used to dissipate heat from the stack so that the internal temperature of the stack is al...
