LOS ALAMOS, N.M.-Manhattan Scientifics Inc. said Robert G. Hockaday, a chief fuel-cell
scientist with the company, successfully made a cellular phone call using a phone powered by an alcohol-fueled pre-
prototype micro fuel cell.
A 50-percent methanol water mixture commonly used as windshield washer fluid fueled
the cell.
“We have achieved the minimum of 100 milliwatts of power out-put necessary to keep a phone in
standby mode and simultaneously trickle charge a battery with our pre-prototype system,” said Hockaday.
“We expect to complete a fully working prototype before mid-1999. Our ultimate goal is to maintain a digital
cellular telephone on standby for more than six months and to provide 100 hours of talk time with a single refueling of
several ounces of the methanol/water mix.”
