Suspended Anode-Type microbial fuel cells for enhanced electricity generation
RSC Advances, 2020Co-Authors: Yiyang Liu, Di Yin, Xiaoyan Sun, Lankun Cai, Lehua ZhangAbstract:Electricity generation in microbial fuel cells can be restricted by a few factors, such as the effective area of the Anode for biofilm attachment, diffusion limitation of substrates and internal resistance. In this paper, a suspended Anode (carbon-based felt granule)-Type microbial fuel cell was developed to make full use of the volume of the Anode chamber and provide a larger surface area of the Anode for the growth of exoelectrogenic bacteria. The current collector was rotated in the anodic chamber to contact with the suspended granules intermittently and achieve better mixing. The open-circuit voltage reached steady state at around 0.83 V. The maximum power density obtained from each scenario increased steadily with the increase in mixing rate. The internal resistance decreased when the rotational rate and the content of the carbon granules were increased. The maximum power density reached 951 ± 14 mW m−3 with a corresponding minimum internal resistance of 162.9 ± 3.5 Ω when the mass of carbon granules was 50 g and the rotational rate was 300 rpm. The suspended microbes made negligible contribution to the power density. The microbial fuel cell with a higher content of carbon granules had lower coulombic efficiency and lower relative abundance of exoelectrogenic bacteria.

Plasma-induced cathodic discharge electrolysis to form various metal/alloy nanoparticles
Russian Journal of Electrochemistry, 2010Co-Authors: M. Tokushige, Tokujiro Nishikiori, Yasuhiko ItoAbstract:Nanoparticles of various elements such as Si, Al, and Zr were formed by plasma-induced cathodic discharge electrolysis in molten chloride electrolyte under a 1 atm Ar atmosphere. Al and Si nanoparticles with 100 nm diameters were obtained from an LiCl-KCl-CsCl melt at 300°C. Zr nanoparticles with diameters less than 50 nm were obtained from an LiCl-KCl at 450°C. Then with a newly designed and constructed “rotating disk Anode Type electrolytic cell”, Ti nanoparticles with diameters less than 20 nm were obtained. Finally, to find more appropriate condition for obtaining finer and more uniform nanoparticles, the effects of the pulse conditions of the applied current and the rotating velocity of a disk Anode on size and morphology among the obtained nanoparticles were investigated by choosing Ni nanoparticle formation as an example. The results showed that quick removal of the formed fine nanoparticles from the melt surface, where the discharge column is standing, is the most important factor to obtain smaller and more uniform nanoparticles.

Formation of Fine Ni Nanoparticle by Plasma-Induced Cathodic Discharge Electrolysis Using Rotating Disk Anode
Journal of The Electrochemical Society, 2010Co-Authors: M. Tokushige, Tokujiro Nishikiori, Yasuhiko ItoAbstract:Fine nanoparticles of Ni were formed in molten LiCl―KCl―CsCl electrolyte under 1 atm of Ar atmosphere by plasma-induced cathodic discharge electrolysis using the rotating disk Anode-Type electrolytic cell. The relations between the size of the formed nanoparticles and the electrolysis conditions, such as the rotation speed of the disk and the electrolysis current value, were investigated. Ni nanoparticles with diameters of less than 10 nm were obtained at a rotation speed higher than 2000 rpm. The size of the obtained Ni nanoparticles depends on the rotation speed of the disk but not on the electrolysis current value. Based on the obtained results, the particle growth process just under the discharge is discussed.
