Abstract

An anode-supported honeycomb SOFC can achieve high volumetric power density and improve thermo-mechanical durability at high temperatures. We have so far fabricated the honeycomb cell with a cathode layer made of La0.7Sr0.3MnO3 (LSM) and an electrolyte layer of 8YSZ on a porous anode substrate in honeycomb form of Ni/8YSZ. In the present study, current-voltage characteristics of the cells having different porous substrate thicknesses and anode/cathode flow channel configurations are studied under different flow rates of fed hydrogen to clarify the effect of 3-dimensional fuel transport in the anode porous substrate on the cell performance. We also estimate the hydrogen mole fraction distributions in the honeycomb cell with different anode substrate thicknesses using the finite element method, and discuss appropriate porous anode substrate thickness.
