Fuel Cells are DOA. The touted range of Hydrogen is ~420 miles, meaning most fill up bi weekly for 12K miles/year. Very cool, Right? The problem is, one virtually never needs an external charging station with a PEV. Exit car, close door, plug-in.  So the range of a PEV is infinite 99% of the time, and you always leave your house fully tanked. Of course on long trips, the 420 mile range is important, right?  No. On a 12 hour trip people stop 2 to 3 times anyway for breakfast, lunch, coffee, bathroom, etc, so anything past say 5 hours (300 miles) is simply superfluous, so the 420 buys Toyota nothing really.  What is significant however is cost.  Hydrogen unfortunately costs as much as gas, while home electricity is 25% of that, and free if you use Tesla\'s super charging stations. You can travel across the US at no cost. Of course if you really require a speed refill, Tesla thinks it can get fast charging down to 5 minutes, or maybe the battery swap model might work.

However, the biggest obstacle to hydrogen is the exorbitant cost of infrastructure. The cost to convert a single gas station to hydrogen costs over a million. With PEV\'s, the infrastructure is already in place, all the way to your home.  Since everyone fuels their PEV at home, the number of external electrical charging stations needed is a small fraction of present gas stations we have now(~121,000).  To convert the gas station infrastructure to hydrogen for all 121,000 filling stations now present will be a quarter to a half a trillion dollars. Those costs come from somewhere.

Of course, California is the first state to try to adopt fuel cell technology, and they are going to have a whopping 100 hydrogen fuel stations  around LA.  People better know where these stations are, and expect to drive 10-20 miles just to fill up each time. You are also back to range issues. You can\'t go across country in a hydrogen car until infrastructure is in place. The Tesla infrastructure now spans the US, and is growing very rapidly (and only costs 300K to build).  And remember, these stations are only for people travelling long distance, no one else needs to charge away from home.

Think about it? Who is going to buy a hydrogen car? Price of fuel, 400% more expensive than PEV. Ability to find fuel, difficult to impossible depending where you go. Maintenance of Fuel Cells, more costly than PEVs. Performance, 135hp compared to 0 to 60 faster than a Porch. Infrastructure is going to cost half a trillion or so. This is a VHS vs BetaMax style competition, except it is Ironman vs Scooby-doo.
