Doesn't seem like they increased the efficiency of the catalyst, only changed the amount of the catalyst used. The surface area stayed the same but the catalyst layer is thinner which resulted in cost saving. Yes it is cheaper, but the cell is not more efficient. It is only efficient use of platinum.So you disagree with the article which says

"...dividing normally expensive platinum metal into nanoparticles...By dispersing the platinum, each and every one of the atoms increases efficiency,"
-and if so, why? Is it perhaps because you didnt read it?
Perhaps you didn't read my commentPerhaps you didnt read your comment. You said

You guys are quibbling over details. The researchers are using platinum more efficiently because they now get more catalysis using less platinum. The platinum does not catalyze more efficiently per atom, but does per gramYou didnt even read the first freeking paragraph

May 23, 2013Just not cheap or efficient enough.
Faster please.
