Microbial Fuel Cells

Microbial Fuel Cells

Microbial fuel cells (MFCs) are bioelectrochemical devices that generate electricity by exploiting the metabolic processes of electrogenic bacteria. These systems provide a renewable energy source and serve as an innovative method for treating organic waste, such as wastewater.A typical MFC consists of two chambers: an anoxic (oxygen-free) compartment that houses the bacteria and an oxic (oxygen-rich) compartment that contains oxygen as the terminal electron acceptor. Many MFCs use proton...

Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Area of Science:

Materials Science
Electrochemistry
Energy Conversion

Background:

Solid Oxide Fuel Cells (SOFCs) are advanced energy conversion devices.
Developing efficient and stable anode materials is crucial for SOFC performance.
Current state-of-the-art anodes, like Ni-YSZ cermets, have limitations, especially with hydrocarbon fuels.

Purpose of the Study:

To synthesize and characterize a new SOFC anode material based on oxygen-excess perovskite related phases.
To evaluate its electrochemical performance under hydrogen and methane fuel conditions.
To assess the material's stability and performance under various operating conditions and configurations.

Main Methods:

Synthesis of oxygen-excess perovskite related phases for SOFC anodes.
Electrochemical performance testing under humidified H(2) and CH(4) at 950°C.
Anode configuration studies (one-layer and four-layer).
Long-term stability testing under alternating reducing/oxidizing conditions and temperature cycling.

Main Results:

The new material shows better electrochemical performance than alternative new anodes and comparable performance to Ni-YSZ cermets under H(2).
Enhanced performance under methane operation with high open circuit voltages (1.2-1.4 V at 950°C) without excess steam.
Optimized electrode polarization resistances of 0.12 ohm cm(2) (H(2)) and 0.36 ohm cm(2) (CH(4)) at 950°C.
Power densities of 0.5 W cm(-2) (H(2)) and 0.35 W cm(-2) (CH(4)) achieved.
Very low anodic overpotential (100 mV at 1 A cm(-2)) under humidified H(2) at 950°C.
Stable electrode performance and open circuit voltages demonstrated over two days of testing.

Conclusions:

Substituted strontium titanates are highly promising anode materials for SOFCs.
The developed material offers excellent performance and stability, particularly for methane utilization.
This research contributes to the advancement of SOFC technology for efficient energy conversion.
