138625 - Modeling Fuel Cells Using Simscape 

Abstract: 

Fuel cells are an important technology in the quest for clean, efficient, and sustainable energy sources. As they become a more viable solution, accurate and quick modeling becomes key to reduce hardware iterations and decrease time to market. Modeling also allows for further research to be done to improve efficiency and output without the associated lab costs. Simscape's physical network approach allows for the creation of component-based models that are representative of the actual physical systems (Figure 1). We will discuss how Simscape's libraries can be used to model the various aspects of fuel cells, including the electrochemical reactions, the flow of gases, the thermal management, and the electrical behavior of the fuel cell stack.

In this talk, we will demonstrate how to set up a basic fuel cell model in Simscape, illustrating the process of assembling the necessary components and configuring their parameters to mimic real-life behavior.

·         Multiple approaches: Simscape offers both physics-based and data-driven approaches. Within physics-based, we will discuss repurposing existing domains or using a custom domain for tracking gases. On the other hand, data-driven approaches leverage experimental or simulation data to develop reduced-order models that can capture the system's behavior with reasonable accuracy, using fewer computational resources and modeling effort.

·         Quick design studies: Simscape can be used for advanced analysis, such as parameter sweeps and optimization, sensitivity analysis, and control system design. We will provide examples of how these analyses can lead to improved fuel cell performance, increased efficiency, and reduced costs.

·         Vehicle model: The fuel cell model will then be shown in a vehicle model to react to demands and predict performance (Figure 2). This will include the integration of the fuel cell model with other system components, such as compressors, motors, and power electronics, to simulate a complete fuel cell system.

In summing up the presentation, we will reiterate the powerful role that Simscape plays in fuel cell research and development. By providing a flexible and robust platform for modeling the complex interactions within fuel cell systems, Simscape enables engineers and researchers to push the boundaries of fuel cell technology, leading to more efficient, reliable, and cost-effective clean energy solutions. The attendees will gain valuable insights into the practical application of Simscape for fuel cell modeling and leave with a clear understanding of how this tool can facilitate the advancement of renewable energy technologies.
