Polymer electrolyte membrane fuel cell oxygen reduction reaction

Mani P, Srivastava R, Strasser P. Dealloyed binary PtM3 (M = Cu, Co, Ni) and ternary PtNbM (M = Cu, Co, Fe, Cr) electrocatalysts for the oxygen reduction reaction performance in polymer electrolyte membrane fuel cells. J Power Sources. 2011 196 666-73. [Pg.184]

Let us consider the oxygen reduction reaction (ORR) that occurs in the cathode of the polymer electrolyte membrane fuel cell (PEMFC), in an acidic environment. Although a variety of ORR mechanisms have been proposed, the four-electron pathway is primarily used to characterize the behavior of this reaction at a platinum electrode or a glassy carbon electrode coated with a platinum-based catalyst. The overall reaction is given by... [Pg.420]
