Sweet fuel supply
November 28, 2007Could a fuel cell that runs on glucose save the planet?
A new type of fuel cell powered with glucose derived from biomass is described in the latest issue of the Inderscience Publication International Journal of Global Energy Issues. The experimental device works by using sunlight to convert the glucose into hydrogen to power the cell, which produces several hundred millivolts.
The use of biological resources, such as food waste and managed high-energy crops, are gradually becoming a viable approach to reducing our reliance on fossil fuels. However, imaginative ways to convert these materials into useful, electrical energy are still required. Renewable biomass resources include starch, cellulose, sucrose, and lactose. These complex sugar molecules can be readily converted to the much simpler glucose molecule with little energy cost through fermentation processes.
The glucose could then be used to release hydrogen using enzymes.
It is this last step that chemists Yutaka Amao and Yumi Takeuchi of Oita University, in Dannoharu, Japan, have focused on to build their glucose-powered fuel cell.
The researchers have built the device with a transparent conductive glass electrode coated with a highly colored molecule that can mimic the natural process of photosynthesis. This molecule is incorporated into light-absorbing titania. The coating can absorb energy from sunlight and release it into another chemical layer on the electrode. This is connected to a platinum electrode and the pair is immersed in a glucose solution to complete the circuit.
When light shines on the light-active electrode enzymes in the chemical layer are triggered to react with glucose molecules in the solution and release hydrogen ions, the dissolved hydrogen ions then attract electrons from the platinum electrode, which causes a current to flow through the wire connecting the electrodes.

Glucose Current Events and Glucose News RSSScientists unlock clues for tailoring corn plant for food, energy needs
Scientists have long known that the offspring of two inbred strains tend to be superior to both their parents. Now, a team of researchers including a University of Florida geneticist has discovered clues to why that might be the case for one of the most important crops in the world: corn.
Scripps research scientists find new link between insulin and core body temperature
A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin-a hormone long associated with metabolism and metabolic disorders such as diabetes-and core body temperature.
Cancers' Sweet Tooth May Be Weakness
The pedal-to-the-metal signals driving the growth of several types of cancer cells lead to a common switch governing the use of glucose, researchers at Winship Cancer Institute of Emory University have discovered.
Scientists find molecular trigger that helps prevent aging and disease
Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction-and the reverse, overconsumption-produce protective effects against aging and disease?
Night Beat, Overtime and a Disrupted Sleep Pattern Can Harm Officers' Health
A police officer who works the night shift, typically from 8 p.m. to 4 a.m., already is at a disadvantage when it comes to getting a good "night's" sleep.
Fat collections linked to decreased heart function
Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions.
New study links vitamin D deficiency to cardiovascular disease and death
While mothers have known that feeding their kids milk builds strong bones, a new study by researchers at the Heart Institute at Intermountain Medical Center in Salt Lake City suggests that Vitamin D contributes to a strong and healthy heart as well - and that inadequate levels of the vitamin may significantly increase a person's risk of stroke, heart disease, and death, even among people who've never had heart disease.
Researchers discover mechanism of insulin production that can lead to better treatment for diabetes
How a specific gene within the pancreas affects secretion of insulin has been discovered by researchers from the Hebrew University of Jerusalem, in collaboration with Japanese and American universities.
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system.
Sweet as can be: how E. coli gets ahead
Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut.
