-An auto industry dominated by batteries will reduce platinum demand to 2.5 million ounces in 2050 from 3.4 million ounces. But if fuel cell cars dominate the alternative vehicle segment in Europe, platinum demand is estimated to be 6.6 million ounces in 2050, Griffith said.....

-Fuel cells vehicles, if they do take off, will certainly be a boon for battered platinum producers. While electric cars do not need catalysts and hybrid models require small amounts, fuel-cell powered cars use between five and 10 times more platinum than a diesel catalytic converter, which typically uses three to seven grammes.
