Im interrested to buy. I never heard of any drawbacks concerning these fuelcell vehicles. It was a dream from the get-go and they succeeded in improving them even more with more powerful smaller less costly fuelcell units. Many will buy, it will maybe make a dent on petrol sales and price of gasoline might shrink helping gas car owners like me and 99.7% of the markets that do not own bevs, plug-ins hybrids, hydrogen operated cars and light trucks.

Further progress might be done in the hydrogen infrastructure with hydrogen made at the retail location made with small machineries like electrolizers or natural gas reformers, etc. Even green algae farming can produce hydrogen, so let's go hydrogen, go, go, go, hurry-up, can't wait anymore, lets start the hostilities on conventionnal made petroleum now and forever.

@ Lad, please stop doing pr for raising fuel prices.

You can reform methanol for high temperature PEM fuel cells. Methanol can be made for one dollar per gallon and be carried like regular liquid fuel.

Fast forwarding to the future, please realize that H2 is for more than just use in FCV. H2 will be the equivalent of NG when NG will run out in the future, or even now for countries w/out NG resource. The NG piping to each home and business will upgraded to be H2-compatible as old NG piping are due for replacement. Then, home-based FC will provide backup electricity for wind and solar sources, as well as waste heat for water and space heating. Heat pump can be used in the winter when a lot of heat is needed but not a lot of electricity is needed, in order to double the energy efficiency of H2 utilization.

YOu see, there is a seasonal mismatch of RE production and Energy consumption. Winter uses the most energy but very little solar energy is available, while wind resource in winter may not be as much as in fall or spring. So, H2 is needed as a fuel for winter and for industrial use.

When H2 is ubiquitously available everywhere, then it makes sense to use it in FCV. The H2 is stored in all the pipings going to everywhere, including to the underground H2 reservoir on seasonal scale. So, wherever there are wind turbines and solar panels, one will just need to setup automated H2 electrolyzers located nearby to produce H2 and feed it to the H2 piping that is connected to the entire H2 piping system and underground H2 reservoir. No need to feed the entire electricity from local solar and wind to the grid. For example, you may have a 10 MW of nameplate wind or solar capacity, but you may need only 2-3 MW of inverters and other power electronics because you will send the 7-8 MW of power straight to the electrolyzers. This will prevent the grid from blowing out due to too much excess RE! THis will also minimize investment into grid-compatible electronics, grid-scale e-storage, and transmission capability, and will give cheaper electricity rates for H2 production than if you get it out of the grid and then feed to the electrolyzers!

So, the RE-electricity that is going into making H2 will be a lot cheaper than the RE-electricity from the grid! This will make FCV's energy cost to be the equivalent of BEV's energy cost, discounting the cost of the battery or of the FC + H2 tank. Remember that solar and wind energies are free and vast and nearly infinite, and zero-CO2, so it's only the cost that matters.

When you change the paradigm of solar PV and wind electricity as part of the grid, into solar and wind as part of an energy farm, with direct output into H2, and only a part of it into the grid, then you will be able to appreciate the role of FCV.
Not just FCV, but also home and business-based FC for local power and heat production as backup for intermittently-available solar and wind electricity! Distributed generation via FC along with the use of heat pump can double the energy efficiency, in comparison to the use of grid electricity and direct home NG or H2 for combustion heating.

Now, BEV in the winter will likely be charged from the energy stored in other seasons in the form of H2. In the winter, BEV will not be as efficient as FCV that can use the H2 directly and use the waste heat from the FC for cabin heating and windshield defrosting.

Now, back to the present, today's BEV will most likely be charged from baseload coal plants at night, while FCV will use H2 made from NG. Which vehicle emits more CO2?

Methanol can be made from biomass. Corn stalks can be gasified and synthesized into methanol, ethanol, gasoline, diesel or jet fuel. I have been showing this for years, you would all rather talk about valve timing.

BEVs, even with current USA's electricity sources mix, could provide the cleanest most efficient vehicles. However, the limited range, slow recharges and high battery cost issues may not be solved before 2020+.

FCEVs would not have the same limited range as BEVs and could be refueled much faster, in about 3 minutes. However, low cost distributed hydrogen is an issue to be solved.

FCEVs total efficiency will always be about 20% to 30% lower than total BEVs efficiency but still better than most ICEVs.
