Hydrogen fuel cell with heating function and control method

Abstract

The invention relates to a hydrogen fuel cell with a heating function and a control method. The hydrogen fuel cell comprises an electric pile, a hydrogen cylinder, an air compressor, a hydrogen pipeline, an air pipeline, a humidifier and a control unit. The hydrogen pipeline is sleeved with a heating pipeline, the heating pipeline is provided with a heating water inlet and a heating water outlet,the heating water inlet is connected to a hot water outlet, and a three-phase water pump and a flow meter are arranged. The control method comprises the steps: S1, detecting the real-time temperatureand transmitting to the control unit; S2, judging whether the real-time temperature is less than a temperature threshold value or not, if yes, entering the step S3, and otherwise, entering the step S4; S3, supplying hot water to the heating pipeline, returning to the step S1 and entering the step S5; S4, returning to the step S1 in a drainage state; S5, judging whether leakage occurs or not, and if yes, opening an exhaust valve is opened; and S6, judging whether the smoke signal is greater than a smoke threshold, and if so, starting an automatic fire extinguishing device to cut off the power supply. The cost is not increased, the weight is not increased, and the overall operation safety of the hydrogen fuel cell is improved.

Description

technical field [0001] The invention relates to the application technical field of hydrogen fuel cells, in particular to a hydrogen fuel cell with a heating function and a control method. Background technique [0002] As oil is decreasing day by day and environmental pollution is becoming more and more serious, it is an inevitable development trend to replace oil with new energy sources. The environmental protection advantages of hydrogen fuel cells, which are close to zero pollution, have gradually been discovered by governments of various countries and encouraged to use them. Since the hydrogen used in the hydrogen fuel cell needs to be humidified, the humidified hydrogen is prone to freezing at low temperatures, which affects the normal use of the hydrogen fuel cell. The existing technology installs a hot water pipeline in parallel with the wet hydrogen pipeline to achieve Heating function. At the same time, if hydrogen leaks and is directly discharged into the air, it wi...

Since the hydrogen used in the hydrogen fuel cell needs to be humidified, the humidified hydrogen is prone to freezing at low temperatures, which affects the normal use of the hydrogen fuel cell. The existing technology installs a hot water pipeline in parallel with the wet hydrogen pipeline to achieve Heating function, at the same time, if hydrogen leaks and is directly discharged into the air, it will bring certain safety hazards to the use of hydrogen; at the same time, hydrogen fuel cells will produce wastewater at about 60 ° C, which is usually discharged directly, resulting in waste of heat energy
