Society of Automotive Engineers on Fuel Cells
This link should give you an idea of where things stand with Fuel Cell vehicles in terms of their design.
If things continue as they appear to have done you will see ethanol at the pumps over the next few years. There are several indicators of that. The first is the recent announcement by the US to increase ethanol use to 12 per cent by 2015.
Ethanol is also the least expensive route for fuel producers to take in terms of delivery.
The second indicator is conversion price. On average it is estimated that for each refueling station approximately $600,000 USD would be required to make the conversion to hydrogen delivery versus just $30,000 USD for a liquid fuel.
Ethanol is also the easiest fuel for producers to dominate throughout the entire lifecycle of from corn crops, harvest and refining to metered delivery.
Much importance has been placed on 'reforming' fuels such as ethanol and methanol into hydrogen on-board Fuel Cell vehicles.
To that end, the US Department of Energy invites comments with respect to on-board fuel processing and the June decision it will take on this issue.
