  • Publication number: 20150018200
    Abstract: A method of controlling the de-alloying of metal alloy particles for fuel cell catalyst layers includes a step of forming a two-phase liquid system that comprises a first liquid and a second liquid. The first liquid is immiscible with the second liquid and the second liquid contains an acid. Metal alloy particles are added to the two-phase system to form a particle-containing liquid mixture. The particle-containing liquid mixture is agitated such that etched metal alloy particles are formed. The resulting etched metal alloy particles are then advantageously used to form fuel cell catalyst layers.

  • Publication number: 20140349843
    Abstract: Methods for forming novel fuel cell catalysts are described. The catalyst has a physical structure that is the inverse image of a plurality of hierarchically structured sacrificial support particles. The particles may be formed independently and then infused with one or more transitional metallic salts and nitrogen carbon precursors, or the sacrificial support precursors, transitional metallic salts, and nitrogen carbon precursors may all be combined in such a way that a hierarchically structured sacrificial support with the infused transitional metallic salts and nitrogen carbon precursors is formed in a single step. The infused sacrificial support is then pyrolized, at least once, and the sacrificial support is removed, resulting in the catalyst.
