Problems solved by technology

At lower temperatures, the more moisture that freezes, the worse the generation of usable power output, preventing the fuel cell vehicle from driving properly and causing delays when starting
[0006] Although cold start has been controlled based on the temperature of the fuel cell's cooling water at the inlet and outlet, the internal state of the fuel cell cannot be accurately estimated when the external temperature changes between when the engine is turned off and when the car is restarted

Abstract

A method for controlling the cold start of a fuel cell vehicle includes detecting and saving the temperatures at the inlet and outlet of the fuel cell cooling water several times after the fuel cell vehicle is turned off. Based on the lowest temperature among the stored temperatures, and when restarting the car, the temperatures at the inlet and outlet of the cooling water, the starting sequence is controlled. Thus, by controlling the cold start sequence according to the internal state of the fuel cell stack, starting stability and driving stability can be enhanced.

Description

technical field [0001] The present invention relates to a method and device for controlling the cold start of a fuel cell vehicle, and more particularly, relates to the ability to improve the performance of the fuel cell by controlling the cold start of the fuel cell vehicle after checking the state of the fuel cell stack when the vehicle is turned off. A cold start control method and apparatus for a fuel cell vehicle that combines the durability of the fuel cell vehicle and the starting stability of the fuel cell vehicle. Background technique [0002] Generally, a fuel cell vehicle includes a fuel cell stack having a plurality of stacked fuel cells serving as a power source of the fuel cell vehicle, a fuel supplier that supplies hydrogen, etc. An air supplier for oxygen of an oxidant necessary for chemical reactions, a water and thermal controller for controlling the temperature of a fuel cell stack, and the like. [0003] The fuel supplier decompresses the compressed hydr...
