It is essential to choose the correct cold-start strategy to successfully start a PEM fuel cell system at sub-zero temperatures.

In this free webinar, AVL’s Dr Reinhard Tatschl and Dr Christoph Pötsch present a multi-physical system simulation solution that offers detailed insight into the cell.

The experts explain how to study the formation of liquid water and freezing / de-freezing processes in the PEM fuel cell stack during cold start and discuss how to ensure self-sustained electrochemical reactions and proper heat-up characteristics.

Key topics and takeaways:

• Multi-physical simulation platform for supporting fuel cell system development
• Scalable modelling depth from 1D to 3D for cell, stack and system
• Electrochemical PEMFC stack model comprising water management (with phase transition to liquid and frozen), species cross-diffusion and thermal effects
• Automated workflow for parameter identification, validation and model generation
• Numerical robustness enables fast simulation time in the office and unconditional real-time capability on the VTB
• Flexible and configurable result quantities definition and display
