Why we don't have fuel cells really

'The major shortcoming associated with platinum is that the cost of using it in a 100kW electric engine is more than the total cost of a 100kW gasoline engine. Furthermore only 3 million 100kW vehicles can be manufactured using the present annual world production of platinum, which is enough for less than one-twentieth of the present annual global production of vehicles.'

I never knew this was the limit on fuel cells. I knew platinum was used but I thought as a catalyst that it was used in small quantities. The big win here is the search for longer life batteries for laptops as an intermediate before an automotive use.
