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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
