This paper proposes a new method to raise the power of the Solid Oxide Fuel Cell (SOFC) stacks in a coal-fired SOFC-based power plant to solve the sulfur contamination problem of the SOFC stacks. Rather than rapidly raise the power demand from the DC link and therefore the SOFC stack in a single step, the method raises the power demand from the DC link gradually in multi-steps. As a result, a much...
This paper presents a power management system for energy harvesting with multiple microbial fuel cells (MFCs), devices that can generate electricity in water environments using electro-chemical reactions caused by bacteria. The system first connects a capacitor to each MFC in parallel so that the capacitors are charged by the MFCs. Then the system disconnects the capacitors from the MFCs, connects...
This paper presents a system that can harvest energy in the water and use the harvested energy to power electronic devices deployed in the water. The system consists of a microbial fuel cell (MFC) and a power management system. The MFC uses electrochemical reactions and bacteria that exist in the water to harvest energy and generate electricity. The power management system consisting of a charge pump,...
