Study of the factors effect on the power storage and generation of a nano-biomimetic membrane electrode-assembling (NBMEA) for battery/fuel cell dual applications

Chen E.T., Ngatchou C., Advanced Biomimetic Sensors, Inc., US

An unmet need has been identified: a high power and high energy density system that is environmentally safe and economically affordable is in urgent need. E. Chen’s group recently reported an innovative approach: using an [...]

Adsorption-Enhanced Compressed Air Energy Storage

Havel T.F., Energy Compression Inc., US

Adsorption-Enhanced Compressed Air Energy Storage (AE-CAES) uses nano-porous materials to adsorb air. The use of an adsorbent changes the effective equation of state for air, so that it becomes possible to operate the system at [...]

The Design, Installation, and Maintenance of a Village-Sized Solar Power System in Uganda

Osende B.M., Abraham J.P., Mowry G.S., University of St. Thomas, US

A microscale solar power project was completed to provide electricity to a small, remote village in Uganda. The system electrified 50 homes, one school, and one pharmacy with a very low cost. The success of [...]

Increased Bandwidth of Mechanical Harvester

Ahmed Seddik B., Despesse G., Defay E., CEA/Leti-Campus, FR

Mechanical energy harvesters ensure an important electromechanical coupling when their natural frequency matches the input frequency. Nevertheless, in many situations the driving frequency is not known or it might change over time. In that case, [...]

Synthesis of TiO2 Nanotube Arrays for Hydrogen Production from Photo-Assisted Water Splitting Reaction

Kawde A.Y., Vats A., Shende R.V., Puszynski J.A., South Dakota School of Mines & Technology, US

This study focuses on the synthesis of TiO2 nanotube arrays and its application for hydrogen generation from photo-assisted water-splitting reaction. In the synthesis approach, an nt-TiO2/Ti/nt-TiO2 structure was synthesized using electrochemical anodization in fluorine (F-) [...]

Strain effect on the hydrogen storage capacity of graphite oxide

Kim J., Seo M., Kim J., Kang S., Seoul National Univ., KR

Among clean fuel alternatives hydrogen is one of the most attractive fuels due to its abundance, easy synthesis, and non-polluting nature when used in fuel cells. Recently carbon-based materials which have high specific surface area [...]

Investigation of a short stack PEM electrolyzer based on a nanosized IrO2 anode electrocatalyst

Di Blasi A., Siracusano S., Baglio V., Briguglio N., Stassi A., Antonucci V., Aricò A.S., CNR ITAE, IT

Electrolysis systems based on PEMs have a number of advantages in comparison to the traditional alkaline electrolyzers, such as ecological cleanliness, considerably smaller mass–volume characteristics and, essentially, a high degree of gases purity. The main [...]

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 [...]
