Optimal architecture design
A multiphysics model representing the NOAH2 monolithic SOEC stack was established. The developed numerical models accurately capture the electrochemical behavior and transport phenomena within monolith-type SOEC stacks, and allowed for the optimization of the internal design and final architecture featuring:
- Straight gas channels minimizing pressure drops
- Rib/channel ratio of close to 1/1 was found to deliver the most uniform distributions of steam and current.
