Abstract

In order to transfer more fuel of a planner SOFC (Solid Oxide Fuel Cell) from gas channel into porous anode, this paper has designed a novel spiral-like SOFC interconnector, a 3-D model is made by COMSOL 3.5a and the cell was operated with the mixture of H2 and H2O as fuel at 1023K. The result shows that, compared with conventional direct channel interconnectors, the new interconnector in this paper could not only improve the gas velocity parallel to the TPB(Triple Phase Boundary), but also with much higher gas velocity perpendicular to it, which has led to the H2 molar fraction close to the TPB in anode is almost two orders of magnitude higher than that of director channel interconnector SOFC, which would be helpful to improve the electrical performance of SOFCs.
