Developments in Hydrogen Fuel Cells

Microbial Fuel Cells, Features and Developments

Current reliance on fossil fuels is unsustainable due to pollution and finite supplies. Microbial cell factories serve as promising alternatives renewable energy resources. Microorganisms generate electricity in their metabolism; act as catalysts for converting the chemical energy into electricity. In Microbial Fuel Cell (MFC), electrons provided by microorganisms flow through an electrical ext...

Beyond Batteries: Portable Hydrogen Fuel Cells

Recent Developments in Mems-Based Micro Fuel Cells

Micro fuel cells (μ-FC) represent promising power sources for portable applications. Today, one of the technological ways to make μ-FC is to have recourse to standard microfabrication techniques used in the fabrication of micro electromechanical systems (MEMS). This paper shows an overview on the applications of MEMS techniques on miniature FC by presenting several solutions developed throughou...

Recent developments in microbial fuel cells: a review

This review presents microbial fuel cells (MFCs) that convert biochemical metabolic energy into electrical energy. Microbes can be fed with waste products rich in organic matter (domestic wastewater, lignocellulosic biomass, brewery wastewater, starch processing wastewater, landfill leachates etc.) to generate electricity. MFCs can also be used for wastewater treatment, as biosensors and produc...
