Toyota's Fuel Cell Hybrid Vehicle (FCHV) Advanced is part of a development project that aims to put hydrogen fuel cell vehicles in global markets by 2015. In tests by two national laboratories in southern California, the FCHV had a single-tank driving range of 431 miles and an equivalent fuel efficiency of 68mpg. (Source: Toyota)
Excellent post Charles. The company I have a partnership in is now producing our REV 7 on-board hydrogen generator. Our concept will be to "bleed-in" H2 and combine that will fuel promoting improvement in gas mileage. This is not a fuel cell but an installed device producing hydrogen. We have five trial installations so far that generate a 17% minimum improvement in mileage. The package also includes data retrieval so carbon fuel credits can be "booked". It also gives the transportation company indications as to actual savings and information relative to long-haul and short trip numbers. We are working towards installation on 300 and 400 HP diesel engines. These typically get 5 MPG so; any improvement would be a significant cost savings to that industry. Many thanks for the information and it's good to know what others are doing along these lines.
There are still some hurdles for Hydrogen powered cars to be commonplace on the roads, however don't be too quick to discount them. All that is needed is an efficient system for extracting Hydrogen from water that can be used on board a vehicle and all the storage problems dissappear. In fact filling stations would also dissappear as all the vehicle owner needs to do is top up with water from the tap at home.
The nay sayers will talk about this being impossible, but look at the technological achievements over the last 50 years and consider what has been possible that people thought could not be done.
This is a cute engineering exercise but my advice to auto makers is to put these cars in their respective museums right now as an example of an evolutionary dead-end.
As mentioned above, this technology will never scale to the point of providing hydrogen "gas" stations that our mass motoring public could take advantage of. Elements in a gaseous state (also mentioned above) are difficult to maintain and transport. Can you imagine how expensive it would be to transport compressed hydrogen gas from point A to point B?
The real problem with this technology is cost. It's extremely expensive to make, store, transport, and dispense hydrogen gas SAFELY. It will never progress beyond the few science experiments you see in this slideshow.
