Methanol could fuel computers, cell phones

24.03.2003


Because methanol, as a liquid, would be easier to dispense using current infrastructure, it will likely be one of the first fuels for fuel cells.



Speaking at the 225th national meeting of the American Chemical Society March 23-27 in New Orleans, Yu Seung Kim, a former research scientist at Virginia Tech, will report the results of studies at Virginia Tech to determine the optimum materials for use as a proton exchange membrane in a methanol-based fuel cell.

Methanol is the simplest alcohol, explains Virginia Tech chemistry professor James McGrath. When used as fuel, it is diluted with water. In the fuel cell, the methanol-water molecule is stripped of an electron -- the energy source -- then the water and proton cross the proton exchange membrane to the fuel cell’s second chamber, where carbon dioxide and water are created as byproducts.


This paper reports the results of several studies to determine the optimum materials for use as a proton exchange membrane in a methanol-based fuel cell.

McGrath believes that methanol-based fuel cells could be developed before hydrogen-based fuel cells. "A liquid is easier to dispense using current infrastructure than gas," he says.

Methanol is the same consistency of windshield cleaning fluid and almost the same concentration will provide energy for computers and cell phones, McGrath says. "A container something like an ink jet cartridge would power a cell phone for a few days instead of a few hours."

The poster, "Methanol permeation of sulfonated poly(arylene ether sulfone) copolymers (Poly 185)," coauthored by Kim, who is now at Los Alamos National Lab; Limin Dong, Michael Hickner, and McGrath, all of Virginia Tech; and Bryan Pivovar of Los Alamos National Lab, will be presented 6 to 8 p.m. on Sunday, March 23, in the Convention Center Hall G.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
