After spending 70 days driving through 14 countries on four continents, three Mercedes-Benz hydrogen cell vehicles have successfully completed their 30,000-kilometer (18,641-mile) F-CELL World Drive. The trio of B-Class F-CELL automobiles left Stuttgart on January 30th, along with an entourage of support vehicles. After traversing a variety of highways, city streets and even some unpaved country roads, they crossed the finish line in front of Stuttgart’s Mercedes-Benz Museum this Wednesday (June 1st).  Read More

The development of practical microbial fuel cells took a big step forward this week. Research conducted by a team of scientists from England’s University of East Anglia was published on Monday (May 23), in which they revealed that they had discovered “the exact molecular structure of the proteins which enable bacterial cells to transfer electrical charge.” Scientists possessing this knowledge can now start working on technology for tethering bacteria directly to electrodes, which could lead to much more efficient microbial fuel cells – also known as bio-batteries.  Read More

With up to 80 percent of the weight of a soldier’s gear attributable to batteries, the U.S. Army is obviously interested in replacement technologies that deliver a reliable, reusable power source. Chemical Engineering students at Stevens Institute of Technology in New Jersey believe their invention of a microreactor that can convert everyday fossil fuels such as butane and propane into pure hydrogen for fuel cell batteries might be the answer.  Read More

There's no doubt that residents of developing nations can benefit hugely from having mobile phones. This particularly applies to the field of medicine, as the phones allow people living in remote areas to contact health care practitioners, or to use health care apps. Given how unreliable the electrical grid can be in such countries, however, keeping those phones charged can be a challenge. That's why a team from the Harvard School of Engineering and Applied Sciences (SEAS) is working on a microbial fuel cell-based charger – a mobile phone charging system that gets its power from microbes in the soil.  Read More

As anyone who has seen Back to the Future will remember, the movie ended with Doc Brown fueling the time-traveling DeLorean’s “Mr. Fusion” reactor with household waste. Well, a student and a professor from the School of Industrial and Aeronautic Engineering at Barcelona’s Universitat Politècnica de Catalunya (UPC) have taken a step towards making that scenario a reality by adapting a radio-controlled model car to run on hydrogen fuel derived from waste aluminum and water. In a nod to the movie, they have named the car the dAlh2Orean ... as in, d-aluminum-water-rean.  Read More

Mercedes-Benz F-Cell roadshow hits continent number three

Having crossed Europe and North America, the Mercedes-Benz F-Cell roadshow is now in Australia where the green-painted B-Class F-CELL cars are making the long trek from Sydney to Perth. Surrounding the small fleet is an entourage of more than a dozen vehicles including SUVs, Sprinter vans set up as mobile workshops and refuel stations and a semi-trailer laden with striking red full-length cylinders of hydrogen.  Read More

Hyundai's Blue2 fuel cell electric vehicle (FCEV) concept at the 2011 Seoul Motor Show

Hyundai unveiled its new mid-size hydrogen powered fuel cell electric vehicle (FCEV) concept this week at the 2011 Seoul Motor Show. Powered by a 90 kW (120 hp) electric motor that delivers fuel economy of 34.9 km/L (82.1 mpg), the Blue2 (pronounced "Blue square") is intended as a "blue" print for the automaker's future sedans.  Read More

Scientists unveil 'world's first practical artificial leaf'

Leaves – the kind that grow on trees – create energy from sunlight and water through the process of photosynthesis. For over a decade, scientists have been kicking around the idea of creating an "artificial leaf." Such a device would use sunlight to split water into hydrogen and oxygen, which could then be stored in a fuel cell and used to create electricity. A functioning artificial leaf has been created before, but was impractical due to the fact that it was made from expensive materials, and was highly unstable. Now, however, scientists are reporting that they have created a cost-effective, stable artificial leaf.  Read More

Hydrogen has great potential as a clean fuel source for powering our cars and airplanes, but it also poses some big hurdles – in particular, how to store it. Making practical use of hydrogen in gas or liquid form raises difficulties in terms of volume and pressurization – a hydrogen gas tank for a car would need to be around four times larger than current petroleum tanks. Another possible solution is the use of solid state hydrogen and the European Aeronautic Defense and Space Company (EADS), along with the University of Glasgow, hope to boost this approach by developing a new storage system using materials modified at the nanoscale that receive and release the hydrogen at a faster rate.  Read More

The VTT solid oxide fuel cell (SOFC) system prototype is being field tested

VTT, the Technical Research Centre of Finland, is currently field testing a prototype large-scale solid oxide fuel cell (SOFC) that the organization hopes will provide efficient, cheap grid power from natural gas and biogas. The VTT system is unique in that it uses a single 10 kW planar SOFC stack to produce a year’s worth of electricity for a typical apartment block.  Read More
