$NEWH Don't miss this VERY Important point: "Researchers are progressing toward development of platinum-based HER catalysts that use less platinum by an order of magnitude, but with substantially improved stability." Focus on this statement in particular "...HER catalysts that use less platinum by an order of magnitude" Raising a number by an "order of magnitude," means multiplying that number by a factor of 10. Folks, think about that! In plain language, this means 10 times LESS Platinum is needed for the Platinum-based HER catalysts. Major stuff.
