Two-dimensional micro/macroscale model for intermediate-temperature solid oxide fuel cells considering the direct internal reforming of methane

摘要: Abstract In this study, a two-dimensional micro/macroscale model is developed to simulate the operation of anode-supported, planar, intermediate-temperature solid oxide fuel cells (IT-SOFCs) fed with partially reformed methane fuel. The previous for hydrogen-fueled IT-SOFCs extended take into account direct internal reforming (DIR) inside porous cermet anode and multi-component mass transport reaction heat consumption. intrinsic kinetics steam (SMR) at nickel catalyst surface fully considered based on calculation framework under assumption fully-developed laminar channel flow. Using model, detailed investigation methane-fueled IT-SOFC conducted, followed by parametric studies effects inlet temperature, co- or counter-flow configuration, air flow rate, cell length performance.
