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 of LSM and an electrolyte layer of 8YSZ on a porous anode honeycomb substrate of Ni/8YSZ. The anode-supported honeycomb cell exhibited promising volumetric power densities. Effect of flow channel configurations on the cell performance was investigated in terms of the hydrogen partial pressure distribution in the cell under operation as well[1].
In the present study, current-voltage and current-power density characteristics of the cells having different porous substrate thicknesses and anode/cathode flow channel configurations are studied under different flow rates and partial pressures of fed hydrogen. We also investigate performance changes by forced hydrogen flow through the porous anode substrate taking advantage of valves connected to each outlet of the honeycomb cell.
