Problems solved by technology

Therefore, during this current limiting period, when the driver steps on the accelerator pedal, the output of the fuel cell stack is insufficient
[0010] Since it is necessary to increase the insufficient heat dissipation capacity to prevent frequent high-temperature current limiting, it is necessary to consider a method of additionally increasing the heat dissipation area of ​​the radiator, but there are many restrictions due to the vehicle layout
[0011] Also, a high-performance / high-flow rate pump should be used to maximize heat dissipation performance, however, during high output of the pump, when the pressure exceeds the internal pressure level of the fuel cell stack while pumping cooling water, due to the structure of the fuel cell stack, it may Leakage of the fuel cell stack due to this increased pressure

Abstract

A temperature management system of a fuel cell vehicle includes a radiator, a water pump, an ion filter, a flow control valve, a state detector and a controller. The radiator is configured to emit heat generated from a fuel cell stack via cooling water, and the water pump is configured to circulate the cooling water through the system. Additionally, an ion filter is disposed in a branch line branched from a cooling water circulating line connecting the fuel cell stack and the radiator. The state detector is configured to detect cooling water state information and the flow control valve is configured to selectively interrupt a flow of the cooling water into the ion filter; and a controller configured to control an operation of the flow control valve depending on the cooling water state information detected by the state detector.

Description

technical field [0001] The present disclosure relates to a temperature management system and method for a fuel cell vehicle. More specifically, the present disclosure relates to a temperature management system and method for a fuel cell vehicle, which reduces the number of times of entering a high temperature current limiting mode by increasing the cooling water flow rate and correspondingly increasing the heat dissipation in the radiator. Background technique [0002] A fuel cell system configured according to a fuel cell vehicle, comprising: 1) a fuel cell stack for generating electrical energy through an electrochemical reaction of reaction gases, 2) a hydrogen gas supply device for supplying hydrogen (ie, fuel) to the fuel cell stack, 3) An air supply device to supply oxygen-containing air to the fuel cell stack, and 4) a temperature and water management system to dissipate the heat generated by the fuel cell stack to the outside to optimally control the operating temper...
