FUEL CELL COLD START SYSTEM AND COLD START CONTROL METHOD

摘要

A fuel cell cold start system and a cold start control method, the fuel cell cold start method comprising: in a hydrogen path system and a cooling loop system (10E), respectively installing temperature detection units (102A, 2B, 3C, 1D, 2D) and electric heating units (101A, 1B, 2C, 4D); the temperature detection units (102A, 2B, 3C, 1D, 2D) detect the temperature rise in the hydrogen path system and the cooling loop system (10E) and send a temperature signal to a fuel cell controller (5E); when the temperature is too low, the fuel cell controller (5E) controls the electric heating units (101A, 1B, 2C, 4D) installed in the hydrogen path system and the cooling loop system (10E) to power-on and heat until the temperature in the hydrogen path system and the cooling loop system (10E) reaches a predetermined temperature, and then the fuel cell is started. A low power consumption cold start is achieved by means of control, so there is no need to wait a long time for a cold start; the start is fast, the structure compact and easy to implement, production and assembly costs are low, and after-sales maintenance is simple and convenient.
