AVL FIRE™ Multiphysics Simulation of Solid Oxide Fuel Cells and Electrolyzers

The optimization of Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolyzers (SOE) with respect to efficiency and lifetime is a major development focus to paving the way for successful market introduction and usage of SOFCs and SOEs in the context of future energy systems. AVL offers tailored solutions to meet your specific needs.

Dedicated Multiphysics 3D-CFD Simulation

AVL FIRE™ v2016 offers dedicated multiphysics 3D-CFD simulation capabilities to support the SOFC and SOE original equipment manufacturers and supply industry as well as the academic and non-academic research community in analyzing and optimizing the complex fluid-dynamic, thermal and electrochemical processes in the individual SOFC/SOE single cell and stack configurations.


By providing a detailed space and time resolved insight into the complex multiphysics processes in SOFC/SOE cells and stacks, AVL FIRE™ helps to optimize transient start-up and steady state operation with respect to media utilization, temperature and reaction current homogeneity, performance degradation/lifetime aspects etc.
