Cornell researchers devise new method to make metal materials for fuel cells and batteries

Cornell University research in hydrogen fuel cell

Is there a new way to feed hydrogen fuel cell technology? Chemists at Cornell University have developed a new way to make metals that can be used to make catalysts for hydrogen fuel cells and electrodes for lithium-ion batteries. Engineers from the university have created porous metal films using this new method that are 1,000 times more conductive than other metal materials. These metals are comprised of nanostructures that help them catch and utilize chemicals that come their way. Researchers say that this new method has given them higher levels…

Direct methanol fuel cells could lead to consumer acceptance of hydrogen energy

Verizon solar energy

Alternative energy is becoming a popular subject as more people grow conscious of their impact on the environment. As such, more attention is being drawn to various types of energy systems that have, until recently, been ignored by the community at large. One of these energy systems is direct methanol fuel cells (DMFCs). These variants of the hydrogen fuel cell were first developed by the Caltech/NASA Jet Propulsion Laboratory with the help of the University of California in 1990. Unlike their hydrogen counterparts, these fuel cells are well suited for…

Butterfly wings may hold the key to hydrogen fuel cell efficiency

Hydrogen Fuel Cell

Researchers from the Shanghai Jiaotong University in China have been working on a way to boost hydrogen fuel production. Their efforts were spurred by the growing demand for hydrogen gas, which has been driven by the increasing popularity of fuel cells. The auto industry has been a champion of fuel cells and hydrogen energy for the past several years and most major car makers will be releasing hydrogen-powered cars in 2013 and 2015. As these vehicles become commonplace, the need for hydrogen fuel is expected to reach critical mass. Researchers…

GreenCell Inc. launches new stack design for solid oxide fuel cells

Clean Transportation Success

GreenCell Inc., a designer of hydrogen fuel cells, has announced that it has completed development of a new fuel cell stack design that will help improve efficiency of hydrogen energy systems. The stack was designed for the company’s UltraTemp-C models, but could conceivably be utilized in the fuel cells from other companies. GreenCell believes that the new stack design will help cut the costs associated with fuel cells. The design will not have a dramatic impact on the cost of production, but will help make maintenance more cost effective. The…

Virginia Tech researchers create a synthetic jellyfish powered by hydrogen energy

Robojelly Video

Researchers from the Virginia Polytechnic Institute have created a robotic jellyfish called Robojelly. The synthetic jellyfish was created using carbon nanotubes to grant it the same flexibility that its organic counterpart enjoys. The creation exhibits characteristics that make it a prime candidate for underwater search and rescue endeavors and may, one day, fulfill this purpose. One of the most intriguing aspects of Robojelly is that it may never run out of energy. The robotic jellyfish’s “skin” is coated in the same platinum catalyst material that is found in hydrogen fuel…

Brookhaven scientists create new fuel cell catalyst that can convert gases into liquids

Brookhaven National Laboratory

Researchers from the U.S. Department of Energy’s Brookhaven National Laboratory have developed a new fuel cell catalyst that is much different from its conventional counterparts. In a fuel cell, catalysts are used to generate chemical conversions and produce hydrogen gas. These catalysts are typically made of a significant amount of platinum, making them expensive enough to be unviable for widespread commercial use. Scientists at Brookhaven believe that their latest development could change all of that. The catalyst they have created is capable of generating hydrogen gas. It can also take…

UCLA researchers develop new graphene supercapacitors that store massive amounts of energy

Hydrogen Research

Researchers from UCLA have developed a new way to produce supercapacitors. Supercapacitors are the common term referring to electrochemical capacitors. These technologies are capable of storing massive electrical charges and can discharge this energy more quickly than batteries. Supercapacitors are often considered the best form of energy storage currently available, but their production is costly and time consuming. UCLA researchers believe they have solved the problem of cost by using graphene, an allotrope of carbon. By using graphene, researchers have been able to construct affordable supercapacitors that are significantly more…

California researchers use nanotechnology to make nanotrees

Hydrogen fuel research

Engineers from the University of California San Diego have been experimenting with nanotechnology. Their efforts are largely fueled by last year’s development of the world’s first artificial leaf from the Massachusetts Institute of Technology. The leaf is capable of perfectly replicating photosynthesis, producing electricity and hydrogen gas by absorbing sunlight. USC researchers are taking the concept of an artificial leaf a step further. They are working to create nanotrees. The artificial trees are meant to mimic plants in their natural environment. The trees are comprised of nanotubes and various other…

British scientists used printed circuit boards to create fuel cells

Example of Printed circuit board

Scientists from the Imperial College London and the University College London have found a way to reduce the cost of hydrogen fuel cells. Price has long been a detractor from hydrogen’s appeal as a form of energy. Fuel cells, the machines that turn hydrogen gas into usable electricity, are notoriously expensive. They require costly components in order to operate, none of which are as high-priced as platinum. London scientists believe that there is no need for fuel cells to be so expensive, thanks to printed circuit boards. Researchers believe that…
