Most commercially viable fuel cells contain a first stage catalyst which break down a hydro-carbon fuel (petrol or similar) to produce hydrogen and CO2. Obviously for racing, the extra weight of the first stage is avoided by loading up on pre-prepared hydrogen.
The difference in emissions is from the efficiency of the whole system - somewhere under 35% for a conventional IC engine drivetrain, and around 85% upwards for a hydrocarbon/fuel cell drivetrain. Meaning far more than twice the power delivered carbon emissions created.
Longer term, it is easy to replace the first stage with out-of-car hydrogen generation, if and when clean hydrogen becomes cheap and easy to transport. The second stage (the actual fuel cell) remains unchanged.
As with all technologies, it is an incremental process. However, a >50% cut in emissions is a breakthrough - once cells become viable, stable and maintenance free for long term use (still a number of years off), they will be everywhere. In the mean time, the electric drivetrain components are already being implemented, and constantly improved, in full electric cars and hybrid electric vehicles.

Image is a part of it, but it is mainly a development thing. A way of having competing sets of engineers come up with a better system.
Early race cars were very different than what are commonly raced today. In fact they looked a lot like go carts do. Fast forward 60 years or so, and the cars look a lot more like real cars.
I'd be surprised if fuel cell cars are any different. But that notwithstanding, having races of this sort would definitely sort out any safety issues pretty quickly. After a few crashes, I'

Fuel cells are not "a good thing". They're an incredibly expensive boondoggle that's been leaching money from electric vehicles. Let's compare and contrast FCVs with BEVs that use modern automotive li-ions (phosphates, stabilized spinels, titanates, etc).
They're roughly a third the efficiency of EVs. Even if you use cleantech to create the hydrogen, you're still talking three times the coastline covered in wind turbines, three times the desert land covered in solar, three times the rivers dammed for hydro, etc -- not good. Even if your electrolysis was near lossless, as a couple techs in the lab are proposing to do, they're still nearly twice as wasteful as EVs. Even hydrogen from natural gas reformation compared to EVs powered by natural gas power plants is *still* significantly more wasteful for fuel cells ((25% efficiency versus 35% [sciencedirect.com]).
Hydrogen is expensive; electricity is dirt cheap. Hydrogen is fundamentally always going to be more expensive because it's such a PITA to handle -- leaks through practically anything, embrittles metals, is corrosive, etc -- and not to mention, poses safety and environmental risks.
Safety? Autmotive li-ions can be abused to heck and back without starting a fire -- discharged to 0V, overcharged, punctured, etc; the electrolyte is generally flammable, but no moreso than gasoline. Hydrogen is an incredibly combustible substance -- burns in almost any fuel air mixture, very vigorously, with a very pale blue, hard to see flame; rapidly evolves deflagrations into detonations in atmospheric conditions; pools under overhangs; can be ignited with less than a tenth the ignition energy of gasoline; enters pipes and tubes and follows them to their destinations, pooling there; etc. Liquid hydrogen is even worse; it acts like a high explosive. Check out NASA's safety guidelines [64.233.167.104] for dealing with hydrogen to get an idea of how much of a pain it is to handle.
Fuel cells are ridiculously expensive. Here, go shopping [fuelcellstore.com]. A good chunk of that price is due to the price of platinum, one of the rarest elements on the planet, although things like Nafion membranes don't help the price, either. Getting fuel cells for $10/W would be an outstanding price. Your average car will need ~10kW to maintain highway speeds, and more for accel/decel, so you're looking at hundreds of thousands of dollars. Automotive li-ions, except for the titanates, are usually a little over $0.50/Wh in bulk, and are projected to significantly decline with mass production, since they're not raw materials costs limited. A couple tens of kilowatts (a couple hours of driving at highway speeds) means $10-20k currently, and significantly less in the near future. And to top it all off, the batteries last longer, too. Nafion membranes tend to wear out over time in fuel cells, giving them around five years or so in typical FCV usage (some techs are proposed to raise that). And there are other components to break, too -- fuel cells have moving parts (compressors, pumps, etc), support parts (heaters, etc), and so on. Automotive li-ions will generally last for thousands to even tens of thousands (in the case of the titanates) of cycles. We're talking decades. To give an idea of how durable they are, the Volt is going to come with a 10 year warranty on its battery pack, and all of the other upcoming EV/PHEV makers are similarly talking about very long warranties. They should last the life of the car.
As for range, it's roughly a draw. 200-250 miles is a typical range for a FCV that costs hundreds of thous

I think you do not deserve your 'insightful' one bit. Development platforms for a new technology do not have to be related in shape or function to the end product.
The length of the road on which they function has nothing to do with the length that they could be going to on real roads.
These are just abstractions, and in fact simplify the development process considerably. Think about how much more costly this would be if all these experimental vehicles had to conform to regular road standards and had to take a full complement of passengers.

So how do you think these go-kart "abstractions" and "development platforms" going to impact the wimpy "image" of alternatively-fueled vehicles?
Cause the "image" is all that the GP post was about.

So if people can see electric cars with real performance that would even surpass the petrol counterpart it should make people more likely to change.
Just a tought, but maybe the major car makers WANT this? It seems to me that they produce ugly,slow cars that won't appeal to the masses with a reason. After all, electric cars need much, MUCH less maintenance and spare parts than a petrol car ... Lets hope the smaller manufacturers see the gap in the market.

Actually, that's one of the reasons that it has sold so well. The distinctively "ugly" look of the car shouts I care about the environment, and that's what the hybrid buyers are really after. It's all about the smug sense of self satisfaction that can only be achieved by letting everyone else know how smart and forward thinking you are.

no, i care for the environment, and what i hear among like-minded people: we need an electric car that's PRACTICAL and SIMPLE, like jetta wagon/golf wagon, and if that means we only get 150 miles range, so be it. most people i know that care for the environment don't be smug about it. the ones that are smug about it, don't really care much for the environment.

There's no need for conspiracy theories at this point. Electric cars are constrained by real-world problems enough as it is. Batteries are space-inefficient and don't provide enough power to make a fast car that has a decent range.
