Below is based on the theory of all cars uing fuel cell power trains.

"What about fuel cell power trains? Well folks today’s fuel cells use between one and three ounces of platinum each to produce the equivalent range and performance of a 4-cylinder internal combustion engine powered car. Using the Toyota projection we would need between 100 million and 300 million ounces of platinum each year after 2020.

Today’s global production of new platinum annually is around 6 million ounces. If we add the global production of palladium we get a grand total of 12 million ounces per year. This means that the production of an exclusively fuel cell powered global fleet of OEM cars and trucks in 2020 would use more than the known world reserves of platinum group metals."
