All of this year's R&D 100 technologies will be announced in the September issue of R&D Magazine and the researchers will be honored at a banquet in Chicago on Oct. 14. Past winning technologies in the international judging have included the FAX machine and HDTV.
Polymer membranes make fuel cell production economically viable
McGrath and former student Michael Hickner (who received his Ph.D. in chemical engineering in 2003 and is now at Sandia National Lab) invented a high temperature proton exchange membrane (PEM) for fuel cells. Battelle has optioned rights to the patents and Bhima Vijayendran, Battelle senior research leader and vice president of commercialization, is developing products for commercialization -- introducing BattellionTM membranes for automotive, stationary, and portable power fuel cells.
Fuel cells convert chemical energy from hydrogen or methanol fuels into electrical energy. PEM fuel cells use an ion-containing polymer (a form of plastic) for this process. Electrons are captured to generate electricity and protons pass through the membrane film, then combine with oxygen to create a environmentally neutral water byproduct.
PEM fuel cells can be integrated into stacks to provide from .001 up to 250 kW of power, Vijayendran explained in the R&D 100 entry. Large units could be used in autos an
