Fuel cells are heavy in weight at the moment, and he argues that it is more efficient to burn the hydrogen in a combustion engine (note must be modified to gain extra efficiencies). Unfortunately I can't find to much information on his research, apart from link below
Still part of the problem is storing the hydrogen, as you need very heavy gas containers (heavier than your LPG tanks). But research is being done in storing the hydrogen in a phosphorous material to try and make system lighter and safer.
I am more interested in using Flywheels, as the are making flywheels that can store a crap load of energy per unit weight. You double speed you quadruple energy stored. Also having flywheels that can spin for a year, without being recharged. Also there is some rapid recharge times available for Flywheels. As new stronger materials become available the energy storage per unit weight will increase even more.
The problem with flywheels in car uses is that going over a pot hole could stuff the bearings, but they are overcoming this. The other problem is if the flywheel disintegrates, it could cause some big issues, but using new materials the will give properties that wont lead to total failure.

There may also be issues of drag and friction from the aerodynamics, the suspension and so on being designed for some range of speeds.

The race was to be held in the middle of the mojave desert, which means no shade to be found, and the entire race held during the dylight hours. In other words, the conditions in which they race would encourage the building of a system with few or no batteries at all. Again, encouraging the design of systems that could never become actual products.

While Tires have plenty of room for improvement, none of that comes from race cars of any type. Raceing vehicles do not race when it rains, and tracks are in nearly perfect conditions.

Re:The use of solar cells (Score:2)
I live in Canada and have only seen one application for solar cells here - they're used by one of the cities to power lights that let drivers know about school zones.
A few years ago in Edmonton the EPCOR building installed solar cells on its roof; the power replaces the conventional power supply to the top few floors of the building.
