    I guess you are talking about PEMFC, PAFC technologies… Then total replacement of Pt is challenging at least for near future. But there are successful technologies to reduce the Pt usage by alloying then with other cheaper metals and also by designing better Pt catalysts like size, morphology, Pt-inomer interactions etc.

    Another key is support materials for Pt: once we have any breakthrough carbon or other high conducting materials with great durability, conductivity with decent water transposition, Pt usage could drop exponentially.

    For a period, Pd was shown as an alternative to Platinum, in terms of cost. However, this alternative does not seem very appropriate at the moment.

    In my opinion, the most important part here is trying to increase the catalyst surface area, the most important alternative for any catalyst.

    However, I think that the use of an active support material instead of carbon will be important both at the point of obtaining a bimetallic catalyst and at the point of using a more affordable product.
