Biomass Gasification and Syngas Production for Use in Solid Oxide Fuel Cell: Gas Cleaning and Conditioning, and Performance Tests
Jewulski, J., Stepien, M., Blesznowski, M., Gallucci, K., Barisano, D.
Performance tests have been completed with a SOFC unit fuelled with syngas produced from biomass gasification reactors, properly conditioned and cleaned. Three series of tests at bench and industrial scale have been completed. The results of the tests indicate that cleaned syngas, from both steam blown and oxygen/steam blown gasification reactors, is a feasible fuel for anode supported SOFC cell. Cell performance on cleaned syngas is comparable or better than SOFC cell performance fuelled with the reference, hydrogen/nitrogen gas mixture. Several potential issues for the integrated SOFC/gasifier operation have been identified. Proper humidification of the gas stream, necessary to avoid carbon deposition, is critical for the long term cell performance. The presence of larger amounts of methane and higher hydrocarbons may lead to SOFC cell cracking due to large temperature gradients resulting from internal reforming process.
