Abstract
Biomass is one of the promising renewable energy sources in Taiwan. However, after gasification, there release gaseous fuel and some impurities, such as tar, which make catalyst or anode coking and poisoning, and degrade the performance of fuel cells. Three biomasses, including palm fiber (CSPF), cryptomeria waste (CW), waste sawdust (WS) and one municipal solid waste (MSW) have been tested. Gasification with and without carbonate catalysts, and the reforming of fuel gas by using Ni-CeO2/γ-Al2O3 catalyst were investigated. The improvement on the H2 content in the syngas and the reduction of tar were noted and optimized. The syngas was tested as a fuel for self-assembled SOFC. The output of the SOFC were 1.00 V (open-circuit voltage) and a maximum power density of 62 mWcm-2 at 800oC, which were inferior to 1.10 V and 140 mWcm-2 of using pure H2 as the fuel.
