Review on microbial fuel cells applications, developments and costs.

Area of Science:

• Environmental Science
• Electrochemistry
• Biotechnology

Background:

• Microbial fuel cells (MFCs) show promise for energy recovery in wastewater treatment.
• Industrial application of MFCs is attractive for waste-to-energy conversion, cost reduction, and profit increase.
• Current large-scale MFC implementation is hindered by low performance and high costs.

Purpose of the Study:

• To review MFC applications and developments, focusing on configuration and operating conditions.
• To describe diagnostic techniques and modeling approaches for MFC performance evaluation.
• To include a cost analysis to facilitate MFC market introduction.

Main Methods:

• Literature review of MFC applications, configurations, and operating conditions.
• Analysis of diagnostic techniques for MFC performance assessment.
• Review of various MFC modeling approaches.
• Inclusion of cost analysis for industrial MFC deployment.

Main Results:

• MFC technology has advanced in configuration and operation, but challenges remain.
• Diagnostic tools and modeling approaches are available for performance evaluation.
• Cost analysis indicates economic viability is dependent on material costs and system efficiency.

Conclusions:

• Development of low-cost materials and high-efficiency, durable MFC systems is crucial for industrial adoption.
• Further research into novel designs and operating regimes is needed.
• MFCs have the potential for significant industrial impact if technical and economic barriers are overcome.
