Multi‐functional microbial fuel cells for power, treatment and electro‐osmotic purification of urine

Abstract: BACKGROUND In this work, a small‐scale ceramic microbial fuel cell (MFC) with a novel type of metal–carbon‐derived electrocatalyst containing iron and nicarbazin (Fe‐NCB) was developed, to enhance electricity generation from neat human urine. Substrate oxidation at the anode provides energy for the separation of ions and recovery from urine without any chemical or external power additions. RESULTS The catalyst was shown to be effective in clear electrolyte synthesis of … Show more

“…The quantity and quality of the catholyte is dependent on MFC design, type of feedstock, power output as well as the type, porosity and thickness of the separator. It is suspected this is due to the lower porosity of the ceramic material used for this study compared to previously used terracotta of the same type and thickness 12 where the electroosmotic movement is more prominent. Ceramic diaphragms or separators have been used in electrokinetic studies including electro-osmosis 26 and it shows a movement of cationic species dragging water molecules from the microbial anode to the cathode 13,25 .…”

“…Separated urine as a concentrated stream could make wastewater management easier becoming a source of electrical current, nutrients for fertilizers and disinfectants. This could be achieved within a MFC system, which is purposefully designed to achieve good levels of power performance and -at the same time separate urine feed into the anolyte and newly formed filtrate (catholyte) forming in the cathode chamber 12 . During the MFC operation, as the protons and cations migrate from the anode through the membrane to the cathode, water molecules are simultaneously moved by electro-osmotic drag 13,14 resulting in accumulation of liquid in air-breathing cathode that maintains hydration and prevents salt accumulation both in wastewater 15,16 and urine operated MFCs 12,17 .…”

“…The power output by fine fire clay‐based MFCs was increased by 64 % only by changing the ceramic properties to higher water absorption, reaching up to 1 mW of power (Figure .B) . In a similar small‐scale MFC made of terracotta, the output was reported to reach 2.19 mW with the use of an iron‐based catalyst on the cathode (Figure .C) . These approaches allow the multiplication of small‐scale ceramic units into multi‐modular stacks increasing efficiency of scaled‐up systems.…”

“…[54] In a similar small-scale MFC made of terracotta, the output was reported to reach 2.19 mW with the use of an iron-based catalyst on the cathode (Figure 4.C). [55] These approaches allow the multiplication of small-scale ceramic units into multimodular stacks increasing efficiency of scaled-up systems. In 2019, Salar Garcia et al operated ceramic separator MFCs fed with urine and used Fe-streptomycin derived materials as a cathode catalyst and reached a maximum power density of 104 μW cm À 2 which is the highest ever recorded for MFC treating a real human urine.…”
