Fuel Cell

By relying on a chemical reaction rather than combustion, fuel cells like the Bloom Energy Server are a more environmentally friendly source of electricity than fossil fuel burning power plants – they’re also easier to fit on a residential or commercial block. Unfortunately, their price is still prohibitively expensive for most people. But things are slowly improving as evidenced by Panasonic’s latest “Ene-Farm” home fuel cell, which was jointly developed with Tokyo Gas. Later this year, the unit will be sold in Japan by Tokyo Gas for 1,995,000 yen (approx. US$22,320). Read More
Keeping tabs on the furious rate of technological development happening all around us is no easy task and the passing of another year provides a good excuse to reflect and take stock of the major milestones we've seen. So sit back in your power-generating rocking chair, crack yourself a self-chilling beverage and enjoy our take on the significant trends, technological victories and scientific bombshells of 2012.

General Electric’s research team has unveiled its new Durathon battery, which the company says makes it cheaper to power buses using clean energy. It is used in tandem with a lithium battery and a hydrogen fuel cell, a combination that the researchers say makes it possible for the vehicle to achieve full performance with a much smaller fuel cell than previously possible.

Wetlands are estimated to account for around six percent of the earth’s surface and a new Plant-Microbial Fuel Cell technology developed at Wageningen University & Research in The Netherlands could see some of these areas become a viable source of renewable energy. More than that, the developers believe that their technology could be used to supply electricity to remote communities and in green roofs to supply electricity to households. Read More
What will highway patrol vehicles look like in 2025? That's the question posed by this year's Los Angeles Design Challenge, and Mercedes-Benz has answered with the Ener-G-Force design concept. Despite the brief, the company's North American R&D team hasn't totally abandoned the past in looking to the future, conceiving a rugged, fuel-cell driven concept based on the existing G-Class that would produce its own hydrogen from water on the fly.

In the latest green energy – or perhaps that should be brown energy – news, a team of engineers from Oregon State University (OSU) has developed new technology they claim significantly improves the performance of microbial fuel cells (MFCs) that can be used to produce electricity directly from wastewater. With the promise of producing 10 to 50 times the electricity, per volume, than comparable approaches, the researchers say the technology could see waste treatment plants not only powering themselves, but also feeding excess electricity back to the grid.

A collaborative project involving ECOmove, Insero E-Mobility and Serenergy is aiming to produce a fuel cell range extender for battery electric vehicles (BEVs) that should boost the distance between charges to at least 497 miles (800 km). The first vehicle to receive the new bio-methanol-based Modular Energy Carrier concept (MECc) cells will be the QBEAK car we featured yesterday. Read More

University of Wisconsin-Milwaukee (UWM) have identified an inexpensive nanorod catalyst with efficiencies rivalling that of platinum. Composed of nitrogen-enriched iron-carbon nanorods, the new catalyst holds the promise of cheaper, more efficient microbial fuel cells (MFCs) that generate their own hydrogen from waste water Read More
Materials scientists at Harvard have created a fuel cell that not only produces energy but also stores it, opening up new possibilities in hydrogen fuel cell technologies. The solid-oxide fuel cell (SOFC) converts hydrogen into electricity, and could have an impact on small-scale portable energy applications. Read More
A new implantable fuel cell that harvests the electrical power from the brain promises to usher in a new generation of bionic implants. Designed by MIT researchers, it uses glucose within the cerebrospinal fluid surrounding the brain to generate several hundred microwatts of power without causing any detrimental effects to the body. The technology may one day provide a whole new level of reliability and self-efficiency for all sorts of implantable brain-machine interfaces that would otherwise have to rely on external power sources. If proven harmless, the method could be used to power implants that could, among other things, help the paralyzed regain the ability to walk. Read More
