Abstract: This paper studies the multi-channel planar anode-supported solid oxide fuel cell (SOFC). The simulation model of a threedimensional multi-channel counter-flow steady-state SOFC was built based on multi-physics coupling model in COMSOL software by using mathematical models of energy conservation, mass balance and momentum conservation combined with operating principle of SOFC. The distributions of velocity, concentration and current were calculated to discuss their influence on the performance, and the inner connections among different parameters were analyzed at the same time, which would lay the foundation for optimizing the control of operation condition and the structure design.
Key words: solid oxide fuel cell; COMSOL; numerical simulation; current density
