  • Unitized electrode assembly with high equivalent weight ionomer
    Patent number: 10505197
    Abstract: A catalyst layer for use in a fuel cell includes catalytic nanoparticles and a perfluorosulfonic acid (PFSA) ionomer. The catalytic nanoparticles have a palladium or palladium alloy core and an atomically thin layer of platinum on an outer surface of the palladium or palladium alloy core. The PFSA ionomer has an equivalent weight equal to or greater than about 830. A unitized electrode assembly is also described.
    Type: Grant
    Filed: March 11, 2011
    Date of Patent: December 10, 2019
    Assignee: AUDI AG
    Inventors: Krista Marie Shoemaker, Robert Mason Darling, Laura Roen Stolar, Elise Lorraine Izzo
  • Fuel cell catalyst treatment
    Patent number: 9484582
    Abstract: According to an embodiment, a method of preparing a catalyst for a fuel cell component includes soaking catalyst particles in citric acid. The catalyst particles are then rinsed after having been soaked in the citric acid. Catalyst particles are dried after they have been rinsed. When desired, the pre-treated catalyst particles may be incorporated into a catalyst ink used for making a fuel cell component.
