Ethanol Powered Fuel Cells : DigInfo

Kyushu Institute of Technology research group proposes using ethanol as a direct fuel in next-generation fuel cells.

Ethanol powered fuel cells up to now have had a number of drawbacks including low catalytic performance, poor fuel cell efficiency, and a decrease in open voltage due to ethanol crossover when the ethanol concentration was increased to boost efficiency. The Kyushu University research group is proposing the use of a direct ethanol fuel cell to address these problems.

First, it is possible to boost the fuel cell performance while operating at room temperature by using oxidized nanoparticles as the anode catalyst. Next a composite catalyst is used for the cathode catalyst. This arrangement curbs the decrease in the open voltage caused by ethanol crossover, and makes it possible to use a highly concentrated ethanol solution.

Researchers are looking to develop a commercially feasible low-load fuel cell that uses ethanol, a renewable fuel, as a direct fuel.

they used platinum as the catalyst... (pt) for platinum.

@HolySpringRolls XD so then, beer is also flamable, yes? ignorance cracks me up. gasoline is FAR more dangerous than a dilute ethanol mix, yet we use that mostly without incident

[habakkuk77777]

hey eveyone,

i have to present a presentation on ethanol fuel cell, anyone has good and different ideas??

[dpark76]

You do realize ethanol is drinking alcohol right? Also these fuel cells do not use 100% alcohol, but rather a diluted solution...similar to the amount of alcohol you'd find in a beer....hardly dangerous.

[HolySpringRolls]

ethanol isnt safe, its flammable.

kind of

[dillj34555]

Rather than burning ethanol in a traditional internal combustion engine, these scientists are turning ethanol into a fuel cell. Is this more energy efficient?

[greyflcn]

What happens when you link two really inefficient processes together?

You get a even more inefficient process.

Not to mention a dirtier process.

and how would you know?

[greyflcn]

Ethanol plus Hydrogen.

Twice the power of stupid.
