【 摘 要 】

PNNL Modeling Activities: Objectives & Approach Objectives: Develop integrated modeling tools to:Evaluate the tightly coupled multi-physical phenomena in SOFCs Allow SOFC designers to perform numerical experiments for evaluation of stack electrochemical, thermal, and mechanical performance Aid understanding of materials degradation issuesProvide wide applicability for industry teams’ to solve key design problems Provide a technical basis for stack design Approach: Multiphysics-based analysis tools SOFC-MP: A multi-physics solver for computing the coupled flow-thermal-electrochemical response of multi-cell SOFC stacks Distributed Electrochemistry (DEC): Cell level multiphysics model to study effects of local properties/conditions on global SOFC performanceReduced Order Models (ROM) to interface with system-level models Micro/meso-scale models to study electrode degradation mechanisms Experimental support to provide necessary material data for the models
