3D Modelling of electrolyzer and fuel cells with NEOPARD-X framework: dimensionality effects

Abstract

Despite significant differences in the used materials, operating conditions and detailed electrochemistry, from the modelling point of view modern promising technologies such as proton exchange membrane (PEM), protonic ceramic cells (PCC) or solid oxide cells (SOC) can be described by common governing equations for mass, charge and energy transport coupled with electrochemical reactions. The generalization of governing equations into conservation form and modular combination of the processes occurring in different phases, and different cell layers, permits a rapid model implementation within the newly developed NEOPARD-X framework.
