Urea - Hydrogen Compost Soil Microbial Fuel Cell for Multifunctional Applications

Abstract

Abstract Background: This paper provides an overview of the present advances in renewable and sustainable energy resources used for new energy demand in the world. Aiming to address, Urea, Urine resources are abundant like urea-containing wastewater, industrial urea, wastewater treatment plants, becoming an attractive option as anodic fuel for the application in urea fuel cells. And as a hydrogen-rich chemical fuel, urea can also be hydrolysis and electrolyzed to produce hydrogen for energy storage in the near future. Results: We report a novel, urea-hydrogen based compost soil microbial fuel cell (UH-CSMFC). As compost soil is a rich source of bacteria, enzymes, and organic matter, soil provided the necessary ingredients for the operation of the device. While bacteria and enzymes that hydrolysed by urea powered by the fuel cell. The compost soil was also found to exhibit partial electrocatalytic activity itself. This novel UH-CSMFC shows power density of 18.26 mW/m 2 . For continuous operation of the device, and cleaning of the excess of nitrogen compounds from urea fuel (urine, containing different wastewater energy resources). Conclusion: The constant state is the most desirable, where the device behaviour is entirely irreversibly, which helps to feed the device. Thus, the results of electrochemical studies show that the system is suitable for cleaning, hydrogen, power generation by consuming urea as fuel. This multifunctional device is sustainable, cheap, and eco-friendly for the environment.

Key findings

• ▸Urea can be hydrolyzed and electrolyzed to produce hydrogen for energy storage.
• ▸Compost soil exhibits partial electrocatalytic activity, supporting the operation of the device.
• ▸The UH-CSMFC shows potential for multifunctional applications, including wastewater treatment and energy generation.
