Gas Transport and Internal Reforming Chemistry in SOFC Anode Supports and Structures

摘要

Efforts to address deposit formation in hydrocarbon-fueled solid oxide fuel cells have motivated development of advanced anode materials and architectures. The Separated Anode Experiment has been developed to decouple anode internal-reforming processes from electrochemical processes, providing a unique method of evaluating novel anodes and supports. Here, we present experimental and numerical results and compare performance of a Ni-YSZ anode support to a porous metallic support. Additionally, a computational model is developed and utilized as a tool in understanding gas transport and internal reforming processes, and for optimization of anode morphological design.
