Abstract

Abstract:

Anode carbon deposition in solid oxide fuel cells (SOFCs) is a bottleneck restricting efficiency and stabilization. This paper introduces the influence of anode carbon deposition on SOFC, reviews three specific research directions in this area, and exhibits their progress at home and abroad. Furthermore, a complete polarization numerical model of SOFC is established using a user-defined function (UDF) in the CFD software FLUENT. Numerical simulation and analysis of carbon deposition characteristics of a planar SOFC are carried out. First, the governing equations, polarization, and carbon deposition models of the numerical simulation are given. Then the boundary conditions and equation discretization method are introduced. The accuracy of the algorithm is verified by solving an IEA standard problem. Finally, the numerical results of the steady carbon deposition characteristics of planar SOFC demonstrate the following: the carbon deposition rate is relatively high at the fuel inlet of SOFC and rapidly reduces along the fuel flow direction; the generation of carbon deposition is greatly affected by CH₄, but less affected by temperature, and the concentration of H₂, H₂O, and CO gas. Our conclusion is helpful in exploring the mechanism of carbon deposition in SOFC and provides a means for the optimal control of SOFC operating parameters with natural gas as fuel.
