Scientists Unravel the Mysteries of Polymer Strands in Fuel Cells

By | News, Research News | No Comments

From the Journal: The Journal of Chemical Physics WASHINGTON, D.C.– Hydrogen fuel cells offer an attractive source of continuous energy for remote applications, from spacecraft to remote weather stations. Fuel cell efficiency decreases as the Nafion membrane, used to separate the anode and cathode within a fuel cell, swells as it interacts with water.  A Russian…

UNIST Research on High-performance Self-assembled Catalyst for Solid Oxide Fuel Cells (SOFC) Selected as the Front Cover of September 2018 Issue of the Journal of Materials Chemistry

By | News, Research News | No Comments

A recent study, affiliated with UNIST has introduced a novel catalyst that can significantly enhance the performance of perovskite electrodes in Solid Oxide Fuel Cell (SOFC). This breakthrough has been led by Professor Gunatae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Jeeyoung Shin of Sukmyeong Women’s University, Jeong Woo Hn…

A Solar Cell That Does Double Duty for Renewable Energy

By | News, Research News | No Comments

Researchers develop an artificial photosynthesis system that generates hydrogen fuel and electricity at the same time ​ In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun’s energy through “water splitting,” an artificial photosynthesis technique that uses sunlight to generate hydrogen fuel from water. But water-splitting devices have…

Israeli Researchers make a Breakthrough and Master Use of Solar Power to Find a Cheaper Way of Producing Hydrogen

A new st​udy published in Nature Communications presents a breakthrough toward understanding the mechanism of splitting water.  Researchers led by Dr. Arik ​Yochelis and Dr. Iris Visoly-Fisher of Ben-Gurion University of the Negev and the Technion, have cracked the chemical mechanism that occurs during the photochemical splitting of hydrogen peroxide (H2O2) over iron-oxide photo-electrodes. The discovery, they say, could have a significant impact…

Noble Metal-Free Catalyst System as Active as Platinum: Could be very helpful for fuel cells

By | News, Research News | No Comments

The industry has been traditionally deploying platinum alloys as catalysts for oxygen reduction, which is for example essential in fuel cells or metal-air batteries. Expensive and rare, that metal imposes strict restrictions on manufacture. Researchers at Ruhr-Universität Bochum (RUB) and Max-Planck-Institut für Eisenforschung have discovered an alloy made up of five elements that is noble…

DICP Scientists Develop New Hybrid Power Devices Based on Fuel Cells and Supercapacitors
