Company Hoping to Sell Fuel Cells
WOBURN, Mass. — Like a salesman at a party supply store, a technician at the Ztek lab here gently unfolded a Mylar balloon and inserted a little plastic hose to fill it with a gas that made it float stiffly at the end of a string. But the gas was not helium, it was hydrogen.
Even more odd was the source: gasoline.
Ztek's balloons were not for birthday parties but part of a demonstration of making hydrogen for fuel cells, which use that fuel to make electricity.
