I have read the same - as far as I know the technology is changing which allows for higher percentages of platinum in catalytic converters, platinum only, etc., but you are right the cost of changing technologies may not warrant it in the short term. My guess is that platinum prices will probably continue to exceed palladium (though the historical differences have narrowed). If Asian demand for platinum jewellery remains constant or rebounds, I doubt that the substitution effects will be that large + increased production from Stillwater will likely keep palladium prices in check vis a vis platinum (the unknown is the impact of new platinum mines will have on platinum prices 2000+, Russian supply of palladium, etc.).

Bill:

It was my impression that in general platinum was a highly efficient catalyst, while in many applications the palladium/hydrogen relationship was of paramount importance. If true, do these separate roles apply to their use in catalytic converters?
