摘要

作为一种可再生能源,微生物燃料电池(MFC)的低功率密度限制需要进一步发展,这引起了研究人员的兴趣。影响性能的因素有很多,但所有因素的执行都将是昂贵且耗时的。通过对以往研究改进的动态与稳态数学模型相结合,观察微生物类型对动态生物膜形成和稳态OCV的影响,并进行稳态模拟,确定最大功率密度及其对应电压。与前人研究结果相似,异养生物量在75 ~ 100小时内,生物膜厚度为2.087 × 10-4 m,最大OCV为838.93 mV,最大功率密度为2050.12 mW//m2,电压为408.16 mV。在450h ~ 475 h,产孢梭菌生物膜厚度为2.079 × 10-4 m时,OCV值最低,为838.76 mV;在8.48 mW/m2,电压为90.43 mV时,厌氧微生物群落的最大功率密度最低。此外,我们还观察到,高和低的变化会在最短的时间内产生较高的稳态OCV,同时增加功率密度及其相应的电压。@font-face {font-family:"剑桥数学";Panose-1:2 4 5 3 5 4 6 3 2 4 4;mso-font-charset: 0;mso-generic-font-family:罗马;mso-font-pitch:变量;mso-font-signature:-536869121 1107305727 33554432 0;潘诺斯-1:2 15 5 2 2 2 2 4 3 2 4;mso-font-charset: 0;mso-generic-font-family:瑞士;mso-font-pitch:变量;Mso-font-signature:-469750017 -1073732485 9 0 511 0;MsoNormal,李。msonnormal, div. msonnormal {mso-style-unhide:no;mso-style-qformat:是的;mso-style-parent:“”;保证金:0厘米;mso-pagination: widow-orphan;字体大小:12.0分;font-family:宋体;mso-fareast-font-family:宋体;mso-ansi-language: en - us;}。MsoChpDefault {mso-style-type:仅供出口的;mso-default-props:是的;字体大小:10.0分;mso-ansi-font-size: 10.0分;mso-bidi-font-size: 10.0分;无衬线字体类型:“Calibri”;mso-ascii-font-family: Calibri;mso-fareast-font-family: Calibri;mso-hansi-font-family: Calibri;mso-ansi-language:;mso-fareast-language:;} div。WordSection1{页面:WordSection1;}

Dynamic and Steady Model Development of Two-Chamber Batch Microbial Fuel Cell (MFC)
As an alternative source of renewable energy that has piqued researchers’ interest, Microbial Fuel Cell’s (MFC) limitation of low power density requires further development. Various factors affect the performance, but performing all will be costly and time-consuming. Through a combination of dynamic and steady-state mathematical model modified from past research, effect of microbe types towards dynamic biofilm formation and stead-state OCV can be observed, followed by steady-state simulation to determine maximum power density and its’ corresponding voltage. Similarity with previous research has been observed, with maximum OCV of 838.93 mV achieved by heterotrophic biomass in 75-100 hours with biofilm thickness of 2.087 x 10-4 m, while generating maximum power density of 2050.12 mW//m2 and voltage of 408.16 mV. Lowest OCV value of 838.76 mV was observed in C. sporogenes in 450-475 hours with a biofilm thickness of 2.079 x 10-4 m, while the lowest value of maximum power density was observed in anaerobic microbial communities at 8.48 mW/m2 with voltage of 90.43 mV. Furthermore, it has been observed that variations with higher  and lower  results in higher stead-state OCV in the shortest amount of time, while increasing power density and its’ corresponding voltage. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536869121 1107305727 33554432 0 415 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-469750017 -1073732485 9 0 511 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-fareast-font-family:Calibri; mso-hansi-font-family:Calibri; mso-ansi-language:IN; mso-fareast-language:IN;}div.WordSection1 {page:WordSection1;}
