Abstract

Solid oxide fuel cells (SOFCs) are promising high-effective energy conversion devices for wide fuel sources and high energy efficiency. Based on non-linear kinetics at triple-phase-boundary, a three-dimensional model with a single flow channel was constructed. Distribution of mass flow, temperature and current density in a different configuration and working conditions were investigated. Critical factors in voltage output, power output, and reactant utilizations were determined. It is concluded that increasing temperature can give better performances. The increase of inlet flow results in an increased of power density but a decrease of fuel utilization efficiency. The numerical simulation provides a scientific basis for control strategy and structural design of SOFC.
