Abstract
A gas-driven anaerobic fluidized bed microbial fuel cell (GAFB-MFC) was designed and built to investigate the electricity generation performance and the sewage treatment time under different gas velocities, particle sizes and initial bed heights. The closed circuit voltage of the GAFB-MFC reached the highest value of 644.3 mV and the shortest sewage treatment time of 96 h at the gas velocity of 2.00 L/min,the particle size of 1.4 mm and the initial bed height of 10 cm. The open circuit voltage of the GAFB-MFC reached 747.5 mV, the maximum power density was 493.95 mW/m2 and the internal resistance was about 205 Ω. The comprehensive energy consumption of the gas-driven system was proved to be much lower than that of the liquid-driven system. This work is of good significance for promoting the industrialization of the microbial fuel cell technology.
期刊介绍：
Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests:
Formation and synthesis of particles by precipitation and other methods.
Modification of particles by agglomeration, coating, comminution and attrition.
Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces).
Packing, failure, flow and permeability of assemblies of particles.
Particle-particle interactions and suspension rheology.
Handling and processing operations such as slurry flow, fluidization, pneumatic conveying.
Interactions between particles and their environment, including delivery of particulate products to the body.
Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters.
For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
