Abstract

The invention provides an air-cooled fuel cell system and a control method thereof, the air-cooled fuel cell system comprises a fuel cell, a fan and a heater, the fuel cell is located on an air outletpath of the fan so as to cool the fuel cell through the fan, and the heater can heat the fuel cell; the system further comprises a controller and a temperature sensor. The temperature sensor is arranged on the fuel cell to detect the real-time temperature of the fuel cell; the temperature sensor can send the detected temperature to the controller; the controller controls the rotating speed of thefan according to the size relation between the real-time temperature T of the fuel cell and the preset temperature value T, and the controller further controls the heater to be turned on or turned off according to the size relation between the real-time temperature T of the fuel cell and the preset temperature value T. According to the invention, the temperature of the fuel cell can effectively and quickly reach the optimal temperature T < set >, and the effect of quickly and accurately controlling the temperature of the fuel cell is realized.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to an air-cooled fuel cell system and a control method thereof. Background technique [0002] As a clean energy in the 21st century, hydrogen energy has high fuel application efficiency and less environmental pollution. Among them, the fuel cell powered by hydrogen energy is considered as the most potential power generation device. In recent years, a large number of scientific researchers have invested in the research of hydrogen fuel cells. With the development of fuel cell technology, the requirements for fuel cell stack efficiency, fan control system, and cost are getting higher and higher. Compared with water-cooled fuel cells, air-cooled Fuel cells are more economical and portable. [0003] The performance of the cooling system of the fuel cell directly affects the working efficiency and service life of the fuel cell, so how to effectively control the fan is an important f...
