Fuel cell can reduce truck idling, emissionsBy Evelyn Brown A rugged, solid oxide fuel cell developed at Argonne may soon provide a clean, affordable alternative to noisy, emissions-producing overnight idling of tractor-trailer trucks. Fuel cells cleanly convert chemical energy into electricity without combustion and emissions. Fuel cells have been used for decades to power everything from hospitals to space shuttles. Argonnes TuffCell features metal supports for higher mechanical strength, easier fabrication and increased performance at a lower cost than current solid-oxide fuel-cell designs. Developed by the Chemical Engineering Divisions Fuel Cells Materials Group, TuffCell could be ready for commercialization in the next five years. The innovation by materials scientist J. David Carter (CMT) replaces the traditional costly, fragile ceramic cell support with a less-expensive, stronger metallic bi-polar plate. The new design also simplifies manufacturing. Traditional solid-oxide fuel cells, built with ceramic supports, require up to four separate high-temperature processings, or sinterings one for each layer. The Argonne method spreads four thin layers of the oxide and metal materials needed one on top of the other and requires sintering only once. The combination of reduced materials cost and elimination of high-temperature processing steps should significantly reduce the cost of solid-oxide fuel cell production, said Deborah J. Myers (CMT), Fuel Cells Materials Group leader. Impact tests have shown that TuffCell is four times tougher than traditional solid-oxide fuel cells, Myers said. TuffCells should overcome the cost and durability issues that have been barriers to introducing solid-oxide fuel cells as auxiliary power units for tractor-trailers and other portable power applications. Tractor-trailer engines often run overnight to keep refrigeration units powered or to provide electricity for microwaves and cooling or heating in the cab. According to a study by Argonne mechanical engineer Frank Stodolsky (ES), a single long-haul truck idles 1,830 hours a year, while emitting about 22 tons of carbon dioxide, a greenhouse gas; 390 pounds of carbon monoxide; and 1,024 pounds of nitrogen oxides. There are nearly half a million such trucks on Americas roads. Auxiliary power units are beginning to replace idling for economic, efficiency and environmental reasons, as states are beginning to ban truck idling. TuffCell-powered units would offer higher power density and efficiency and would last longer than current units. Until hydrogen is readily available, fuel reformers could reform diesel fuel into hydrogen to run the fuel cell. TuffCell researchers are collaborating with other CMT scientists who patented fuel reforming technology to combine the fuel cell and fuel-reforming technologies. Lab director thanks inventorsArgonne Director Hermann Grunder has thanked Argonne inventors and their division management for reporting new laboratory inventions in the first half of fiscal year 2003. Timely reporting of inventions is an important duty of each Argonne employee, Grunder said, and is the essential first step in a process that protects DOEs and Argonnes intellectual capital. I encourage every employee and all of Argonnes managers to report their new inventions and discoveries. This product of Argonne inventors genius and diligent efforts is greatly appreciated. Inventions can be reported online at www.anl.gov/invent/. Inventors reporting to DOE in the first half of fiscal year 2003 were: Rajesh Ahluwalia, Shabbir Ahmed, Oyelayo Ajayi, Saud Aldajah, Randy Alkire, Khalil Amine, Thomas Askew, Orlando Auciello, Uthamalingam Balachandran, Sergei Bavykin, Ilias Belharouak, Amrit Boparai, Zhonghou Cai, Gerard Caneba, John Carlisle, Kathleen Carrado Gregar, Yung Cha, James Cunnane and Ryan Cunningham.

Plane tickets are top ACA raffle prizeOne lucky raffle winner will win two round-trip tickets from United Airlines to anywhere in the continental United States in the 2003 Argonne Combined Appeal (ACA) raffle. Raffle tickets will be sold during lunch in Argonne-Easts Building 213 Cafeteria Monday, June 30, through Thursday, July 3, and the week of July 7-11. Tickets cost 50 cents each or 12 for $5. Employees can buy tickets from ACA steering committee members and ACA coordinators, or at the Argonne-East picnic. The raffle supports the ACA, which allows employees to contribute money to metropolitan Chicagos United Way/Crusade of Mercy Inc., United Way of Will County and 18 other health and welfare agencies. The raffle drawing will take place at the picnic Saturday, July 12. Winners do not need to attend the event to claim their prizes. Other prizes include gift certificates to Tassos Porterhouse, Omega and Tallgrass Restaurants as well as three one-hour massages from Caring Hands Massage Therapy and a pair of one-night stays at the Baymont Inn. More information is available on the ACA home page. Argonnes glassblower hosts Churchill fellowBy Jennifer Wisz Philip Murray, a 23-year-old recipient of the Winston Churchill Memorial Trust fellowship, traveled to Argonne-East recently to learn from master glassblower Joe Gregar in Argonnes Chemistry Division glass shop June 2-5. Argonne was one of Murrays seven chosen stops as he tours scientific glassmaking shops in Europe and the United States on a Churchill fellowship. The fellowship, a memorial for British statesman Winston Churchill, is designed to help British citizens gather knowledge and experience from different countries. The fellowships are available to any British citizen, male or female, old or young, in any occupation. When they return from the fellowship, their workplaces and communities will benefit from the knowledge they have gathered from studying abroad. Im encouraged to take my time during the fellowship to let everything Im learning sink in, Murray said. Murray worked at Argonne with Gregar to learn and experiment with different glassblowing techniques, equipment and methods. Murray said he has learned about cultural differences in glassblowing from traveling during his fellowship as well. As a master glassblower in Argonnes Chemistry Division glass shop, Gregar creates custom-made and scientific glassware vacuum systems for Argonnes researchers. He also sits as chair of the Junior Liaison Committee for the American Scientific Glassblowers Society (ASGS). The Junior Liaison Committee helps young members of ASGS receive a professional, quality education about scientific glassblowing. Gregar has been chair of the junior glassblowing committee since 1991. Since Murray is still young in the field, Gregar said he has enjoyed teaching Murray new methods and techniques about glassblowing. He said the Winston Churchill fellowship is a wonderful opportunity for a young scientific glassblower who is beginning a career. He gets the social aspects and can learn methods from different artists, Gregar said. For information about ordering glassware, contact Gregar at 2-5549 or at jgregar@anl.gov, or visit the Argonne Scientific Glassblowing home page MANAGEMENT CORNERWarm weather brings out joggers, bicyclistsBy Adam Cohen, EQO Director As summer approaches and the temperatures increases, so does the number of people participating in outdoor activities both on and off site. Both those participating in outdoor activities walkers, joggers, bicyclists and those driving on site need to be more alert and cautious than usual.
Gypsy moth control to begin July 1As part of a gypsy moth control program, the Illinois Department of Agriculture plans to apply pheromone flakes by airplane to wooded portions of Argonne-East and Waterfall Glen Forest Preserve Tuesday, July 1.
