"Micro-Fuel Cell Could Revolutionize Cars, Computers

"CLEVELAND, Ohio, May 1, 2000 (ENS) - A miniature fuel cell with a volume of only five cubic millimeters == the size of a pencil eraser == has been developed by researchers at Case Western Reserve University. The new fuel cell was produced using high tech mini-fabrication techniques.

"'The rash of new electronic products on the market over the last dozen years and the rush to further miniaturize these devices has driven the demand for this technology,' said Robert Savinell, director of the Ernest B. Yeager Center for Electrochemical Science and associate dean of the Case School of Engineering.

"Savinell said for the commercial market, the new miniature fuel cells could be used in everything from automobiles to cell phones and computers. 'The major portion of the weight and volume of a portable computer or cell phone is the battery system. The size of the power pack is a major limitation for portable electronic devices,' he said. (...)

"The team uses minifabrication technology to print multiple layers of fuel cell components onto a substrate that will permit low cost, high volume production of fuel cells rather than building them by hand.

"The goal is to produce fuel cells as integrated circuits are now manufactured. (...) 'We have created inks for each of the materials needed to create the fuel cell, and discovered how to screenprint those inks onto a structure to form a functioning device,' said Savinell.

"'This new miniature fuel cell ripens the conditions to someday create micro-systems == fuel cells coupled with electronic circuitry, micro processors, sensors, and transmitters on a single silicon chip,' he said."
