0520 Effects of Mesoscale Structure of Anode Electrode on SOFC Performance

Abstract

In this study we focus on the possibility of the current density enhancement by controlling the mesoscale structure of the anode electrode. Such structures increase electrolyte surface area, decrease electrolyte thickness and are expected to affect mass transport in the porous electrode and consequently influence the cell performance. To evaluate its effect on the cell performance, an experimental apparatus that can directly compare two different anode electrodes under a same operating condition is designed. By comparing a mesoscale controlled anode with a standard one, it is found that the mesoscale structure affects the cell power generation performance.
