146053 - Analytical Study on the Thermal Performance Characteristics of Fuel Cell Cooling Systems Combined With Heat Pump Technology 

The escalating severity of environmental problems and the rapid progression of global warming have made the transition to sustainable and eco-friendly energy technologies an urgent necessity. Among various sectors contributing to greenhouse gas emissions, the transportation sector stands out as a major source. This highlights the critical need for greener alternatives in transportation, with fuel cell vehicles (FCVs) emerging as a promising solution. FCVs offer a significant reduction in emissions compared to traditional internal combustion engine vehicles, making them a key component in the global effort to mitigate climate change. However, the efficiency and stability of FCVs are heavily dependent on the performance of their fuel cell systems. Within these systems, thermal management is a critical factor that directly influences both performance and longevity.

Proper thermal management is essential to maintaining the optimal temperature of the fuel cell stack, which is crucial for ensuring the system operates efficiently and remains stable over time. If the temperature of the fuel cell stack is not adequately controlled, it can lead to a decrease in system efficiency and potentially cause long-term damage to the system, thereby compromising its stability and lifespan. To address these challenges, this research introduces a novel strategy that incorporates a heat pump system into the fuel cell's cooling system. The primary goal of this approach is to enhance the overall efficiency of the fuel cell system by recycling wasted thermal energy. By doing so, the system can improve its energy efficiency, reduce power consumption, and increase the operational lifespan of the fuel cell.

To evaluate the effectiveness of this integrated cooling system, one-dimensional (1-D) analytical software is employed. This software is used to simulate the thermodynamic processes within the fuel cell system and assess its operational stability under various conditions. The results from the 1-D simulation analysis provide valuable insights into the thermal dynamics of the system, allowing for the optimization of heat transfer within the cooling system. By enhancing thermal management through this integrated approach, the research demonstrates a significant improvement in the operational efficiency of the fuel cell system, which, in turn, leads to reduced power consumption and enhanced overall performance.

The proposed heat pump-integrated cooling system has shown superior performance compared to traditional cooling methods, indicating its potential to significantly reduce energy consumption and greenhouse gas emissions in fuel cell vehicles. This research represents an important step forward in the development of more efficient and environmentally friendly fuel cell vehicles. By providing a viable solution for the effective thermal management of fuel cells, this study contributes to the broader goal of advancing sustainable energy technologies and paves the way for the widespread adoption of green transportation solutions. As fuel cell technology continues to evolve, the findings of this research could play a crucial role in shaping the future of eco-friendly transportation, offering a path toward a more sustainable and cleaner world.
