Design and Fabrication of Hydroelectric Fuel Cell System for Household Power Application

Nguyen K.C., Chung L.T., THLLC Joint Stock Company, VN

A hydroelectric fuel cell system is designed for stand-alone household generator to meet the need of home electricity behind national electrical network in Vietnam. The energy system utilizes water to generate H2 by the reduction [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]

Optimization study of Supercapacitor electrode material composition and thickness for enhanced performance of the Supercapacitor

Ranade A.P., Jung D.Y., Sammakia B.G., Eilertsen T., Davis T., Binghamton University, US

A prototype electrode was constructed to verify the optimization of composition of materials for the supercapacitors. Surface area analysis and SEM images were used initially to select the most appropriate active carbon from a group [...]

(Au, Ag, Ti)-SiO2 Core-Shell Nanoparticles Based Polymer Nanodielectrics for Energy Storage Applications

Badi N., Singh R., Bensaoula A., Rittikulsittichai S., Thanasarakhan T., Randall Lee T., University of Houston, US

This paper addresses materials and processes for energy storage in high k embedded capacitors using metal nanoparticles coated and uncoated SiO2 shells (M@SiO2, where M = Au, Ag, and Ti)) and high K polymer matrices [...]

Overview of four energy storage techniques

Chukwubuikem C., University of Cape Town, ZA

Abstract: Renewable Energy has gained a significant attention in recent years due to high energy cost and adverse environmental impacts of conventional fossil fuels. One of the major challenges for the renewable energy systems remains [...]

Microstructures and electrochemical properties of Si-Ni based alloys

Song J-J, Inje University, KR

In this work, Si-Ni-Al and Si-Ni-Cu-Al alloy ribbons were fabricated by a rapid solidification process to minimize the effect of the volume change of silicon particles. Thin ribbons with thicknesses of 10~20μm were fabricated by [...]

Microstructures and Electrochemical Properties of Rapidly-solidified Si-Mn-Cr alloys

Han H.W., Ahn D.K., Ahn H-J, Ahn D.K., Ahn H-J, Park W-W, Sohn K.Y., Inje University, KR

In this work, the microstructure and electrochemical properties of Si-Mn-Cr alloy specimens prepared by a rapid solidification process and a conventionally-solidified process have been investigated. Si70Mn15Cr15 alloy ribbons by atomic ratio were prepared by two [...]
