They don't say if that is the prototype or expected production cost.
A standard prototype often costs car companies over $1 million each for your everyday gas-powered car.
I have read about this in on-line articles over the past two years. The general agreement is that quantities of millions of cars would lower all production costs to be several thousand more than what we currently pay for our gasoline powered cars.
Keep in mind that advances in fuel cells are coming yearly. That what a company would make today is a generation behind what it would make next year and two generations behind what the company would make in two years. I believe that with current advances, in five years, fuel cell production will be quantum leaps over how a fuel cell would be made today. Look at the advances in gasoline powered cars over the last century.
The infrastructure is bought up repeatedly, but I think it is not relevant. If the following two hurdles can be overcome, (1) an efficient fuel cell manufactured cheaply and (2) hydrogen produced more efficiently (two big ifs), the infrastructure will pop into being overnight because of capitalism.
