Caltech Team Reports On Fuel Cell Advance

Pasadena-based Caltech engineers said this week that they have created a new, propane-burning fuel cell that provides extremely high fuel density in a very small space. A team led by associate professor Sossina Haile of Caltech, reported in the journal Nature that two fuel cells, each smaller than a watch battery, have sufficient power to drive an MP3 player. Fuel cells have been hailed as the next step in efficient power generation. The Caltech technology provides fuel cell power output at lower temperatures than existing fuel cell technology.
