Abstract

One of the major barriers to the commercialization of polymer electrolyte fuel cell (PEFC) power systems, especially for the automotive application, is cost. The high cost is largely due to the use of platinum-containing electrocatalysts in the fuel cell electrodes.1 Toward the goal of dramatically reducing the cost of PEFC cathode electrocatalysts, we are developing non-Pt bimetallic base metal-noble metal nanoparticles, where the bulk of the particle is comprised mainly of an inexpensive base metal and the surface of the particle is comprised of the noble metal. The initial choice of metals for the bimetallic systems was based on surface energy calculations giving the propensity of one metal to segregate to the surface of a bimetallic combination.2 We are currently studyin
