Solution Approach 1:

The emulator introduces an intermediary thermal management system that uses heating elements, temperature sensors, and controlled cooling circulation to reproduce the thermal behavior of real fuel cells. Instead of managing the actual complex electrochemical thermal processes of a fuel cell, the emulator uses simplified thermal simulation components that interact with the fuel cell management system under test. This intermediary approach maintains performance testing accuracy while reducing the complexity and reliability risks associated with real fuel cell thermal management.
