Development of a Digital Twin for PEM Fuel Cell to Reduce Experimentation Costs

Problem Statement

Proton Exchange Membrane (PEM) fuel cells are a promising clean energy technology that converts hydrogen into electricity. However, real-world experimentation and testing of PEM fuel cells involve significant costs due to:

• The high cost of hydrogen production through electrolysis

• The logistical challenges and expense of hydrogen storage

• Efficiency degradation during continuous operation due to water accumulation within the cell

• Extensive need for repeated physical testing to optimize operational parameters

These factors make the traditional experimentation process resource-intensive, time-consuming, and economically unviable for scalable research and development.

Project Objective

The objective of this project was to build a Digital Twin of a PEM fuel cell system using machine learning techniques. This virtual replica simulates the behavior of the fuel cell under varying conditions and helps researchers test configurations digitally. The primary goal was to reduce real-world experimentation costs by at least 80% without compromising accuracy and reliability.

Problem Solved and Key Results

• Eliminated the need for repeated physical tests under varied experimental conditions

• Enabled researchers to simulate hundreds of configurations digitally in a fraction of the time

• Reduced experimentation costs by approximately 80%

• Improved the efficiency of fuel cell R&D workflows

• Provided a scalable solution for future integration with IoT-based monitoring systems and control strategies

Key Contributions
