We are headed towards a society that will be largely unplugged - from fossil fuels, wall outlets, etc. - but this relies on the portability of the power system. What we are trying to do is to bring the revolution of electrochemical energy conversion storage.
A battery is an energy storage device. Fuel cells, however, are energy conversion devices. They allow the conversion of chemical energy to electrical energy. We are working to develop high performance fuel cells using the most efficient and cost effective materials.
