یک مطالعه از استراتژی بهره برداری از ماژول های خنک کننده با استفاده از مدل سیستم سلول سوختی پویا برای برنامه حمل و نقل

A fuel cell system model with detailed cooling module model was developed to evaluate the control algorithms of cooling module which is used for the thermal management of a proton exchange membrane fuel cell (PEMFC) system. The system model is composed of a dynamic fuel cell stack model and a detailed dynamic cooling module model. To extend modeling flexibility, the fuel cell stack model utilizes analytic approach to capture the transient behavior of the stack temperature corresponding to the change of the coolant temperature and the flow rate during load follow-up. The cooling module model integrated model of fan, water pump, coolant passage, and electric motors so that the model is capable of investigation of operating strategy of pump and fan.

The fuel cell vehicle has emerged as a solution stringent exhaust emission regulation such as zero-emission. A proton exchange membrane fuel cell (PEMFC) is the most attractive candidate in many types of fuel cells due to competitive power density, compactness, silent operation, low operating temperature and relatively simple design. To be viable the PEMFC in the market, substantial progress remains to be accomplished in water and management.

A model of a PEMFC stack with a large active area using a water-cooled thermal management system was developed. The results are summarized below. The thermal management criteria were set considering the durability, the transient response, and the efficiency. The proper fuel cell temperature was set to be 348.15 K considering the durability and transient safety margin. The optimal path of the coolant inlet temperature was determined as a trade-off between the maximum power and the minimum parasitic loss.
