Research at the University of Florida's fuel cell lab aims largely at making such fuel cell systems more efficient and less polluting and integrating them with vehicles, he said.

As well as two fuel-cell systems for vehicles (one for cars, another for buses and lorries), there are separate systems for large and small generators fridge-sized units running on natural gas to provide electricity for a building that is not attached to the grid.

The company can also lean on a trade group, the U.S. Fuel Cell Council, whose members range from specialty companies like Fuel Cell Energy and Ballard Power Systems to giants like General Electric and United Technologies.
