    摘要： The invention is directed to high surface area graphitized carbon and to processes for making high surface area graphitized carbon. The process includes steps of graphitizing and increasing the surface area of (in either order) a starting carbon material to form high surface area graphitized carbon. The step of increasing the surface area optionally comprises an oxidizing step (e.g., through steam etching) or template removal from composite particles. The invention is also directed to catalyst particles and electrodes employing catalyst particles that are formed from the high surface area graphitized carbon.

    摘要： A membrane electrode assembly comprises (a) a solid electrolyte polymer membrane; (b) an anode electrocatalyst layer disposed at one surface of the membrane and comprising a first electrocatalyst composition comprising carbon substrate particles and nanoparticles comprising an alloy of platinum and ruthenium disposed on the surface of the substrate particles; (c) a cathode electrocatalyst layer disposed at an opposite surface of the membrane, the cathode layer comprising a second electrocatalyst composition different from the first electrocatalyst composition and comprising carbon substrate particles and nanoparticles comprising platinum disposed on the surface of the substrate particles; and (d) gas diffusion layers disposed over each of the anode and cathode electrocatalyst layers. When operating in a direct methanol fuel cell with an active area of 25 cm2 and under conditions including a supply of IM methanol to the anode electrocatalyst layer at a rate of 3 ml per minute, a supply of air to the cathode electrocatalyst layer at a rate of 400 seem, the membrane electrode assembly provides an output voltage of 0.4 volt and a temperature of 7OoC, provides a power output in excess of 120 mW/cm2 and a normalized performance in excess of 34 mW/mgPt.
