Enhancement of fuel transfer in anode-supported honeycomb solid oxide fuel cells

An anode-supported honeycomb solid oxide fuel cell can achieve high volumetric power density and improve thermo-mechanical durability at high temperatures. We have so far shown the promising power densities and investigated the effect of flow channel configurations on the cell performance in terms of the hydrogen partial pressure distributions in the cell under operation. In the present study, current-voltage characteristics of the cell depending on thicknesses of the porous anode substrate and forced convection in the substrate are studied under different flow rates of fed hydrogen to clarify the effect of 3-dimensional fuel transport in the porous anode substrate on the cell performance.
