Abstract
Samples of biomass from rice straw, wood, and almond shell were directly converted within a solid oxide fuel cell. Measurements of cell performance indicate that for both wood and almond shell samples, a peak power density of 32 and 33 mW/cm2, respectively, was achieved. These results compare favorably with a measured peak power density of 38 mW/cm2 for an activated carbon fuel. EIS measurements verified the DC results and indicated that performance losses from the biomass samples can be attributed to higher resistances at the anode due to both changes in bed reactivity and mass transport parameters. Comparison with previous studies reveals substantial promise for producing a biomass fueled SOFC device with practical applications.
