Abstract

The invention provides a fuel cell waste heat utilization system and a control method thereof, and relates to the technical field of fuel cells. The fuel cell waste heat utilization system comprises an electric pile, a water pump, a heater, a radiator, a flow direction control valve, an expansion water tank, a heat exchanger, a deionization tank, a first valve, a second valve and a third valve, the electric pile, the water pump, the radiator, the flow direction control valve and the third valve form a main flow path, and the electric pile, the water pump, the heater, the flow direction control valve and the third valve form a main heating flow path. The water pump, the heater, the flow direction control valve, the second valve and the heat exchanger form a warm air heating flow path, and the water pump, the first valve and the heat exchanger form a waste heat flow path. The warm air system and the fuel cell system share one set of heater, water pump and expansion water tank, so that the integration degree of the whole vehicle and the fuel cell warm air cooling system is improved, the space of the whole vehicle is saved, the cost of the whole vehicle is reduced, the energy consumption of the vehicle is reduced, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell waste heat utilization system and a control method thereof. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because fuel cells are The Gibbs free energy part of the chemical energy of the fuel is converted into electrical energy through electrochemical reaction. The process does not involve combustion, no mechanical loss, high energy conversion rate, and the products are only electricity, heat and water. The operation is stable and the noise is low. . Known as the "ultimate eco-friendly engine". Compared with traditional vehicles, fuel cell vehicles have zero emissions and zero pollution; compared with electric vehicles, they have a longe...
