Michael Lefenfeld and James Dye of Signa Chemistry wanted to make rooms smell better. Instead, they stumbled on a way that could make hydrogen fuel cells a practical reality.
New York City-based Signa says it has come up with a new--and fairly efficient--way to produce hydrogen, one of the vexing problems for boosters of the hydrogen economy.
Conceivably, the company's technology could be incorporated into fuel cells that could generate enough electricity to run a cell phone for a week, or a car in emergency situations. The company's techniques could also reduce cost and complexity for pharmaceutical manufacturers and petroleum refiners.
