Prediction of MCFC Unit Cell Performance Using 3-D Heat & Fluid Analysis with Electrochemical Reaction

전기화학반응을 포함한 3차원 열$\cdot$유동해석을 통한 용융탄산염 연료전지의 단위 전지 성능해석

An analysis procedure for the MCFC channel flow has been developed to predict the fuel cell performance. The channel formed by the uniformly distributed trapezoidal supports is approximated by the porous medium that yields the equivalent pressure drop. The Wavier-Stokes, energy, and species equations are solved to obtain the velocity, temperature and concentration fields for a local current density which is computed from electrochemical correlations. The fuel cell characteristics, such as the temperature, pressure, mole concentration, voltage and current density distributions, are presented and discussed.
