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, 60-minute 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.
