Patent number: 11973233Abstract: A catalyst structure includes: (1) a substrate; (2) a catalyst layer on the substrate; and (3) an adhesion layer disposed between the substrate and the catalyst layer. In some implementations, an average thickness of the adhesion layer is about 1 nm or less. In some implementations, a material of the catalyst layer at least partially extends into a region of the adhesion layer. In some implementations, the catalyst layer is characterized by a lattice strain imparted by the adhesion layer.Type: GrantFiled: December 11, 2020Date of Patent: April 30, 2024Assignees: The Board of Trustees of the Leland Stanford Junior University, Volkswagen AktiengesellschaftInventors: Friedrich B. Prinz, Shicheng Xu, Yongmin Kim, Thomas Jaramillo, Drew C. Higgins, Maha Yusuf, Zhaoxuan Wang, Kyung Min Lee, Marat Orazov, Dong Un Lee, Tanja Graf, Thomas Schladt, Gerold Huebner, Hanna-Lena Wittern, Jonathan Edward Mueller

Publication number: 20230079048Abstract: A manufacturing process includes: depositing a first catalyst on a first gas diffusion layer (GDL) to form a first catalyst-coated GDL; depositing a first ionomer on the first catalyst-coated GDL to form a first gas diffusion electrode (GDE); depositing a second catalyst on a second GDL to form a second catalyst-coated GDL; depositing a second ionomer on the second catalyst-coated GDL to form a second GDE; and laminating the first GDE with the second GDE and with an electrolyte membrane disposed between the first GDE and the second GDE to form a membrane electrode assembly (MEA). A MEA includes a first GDL; a second GDL; an electrolyte membrane disposed between the first GDL and the second GDL; a first catalyst layer disposed between the first GDL and the electrolyte membrane; and a second catalyst layer disposed between the second GDL and the electrolyte membrane, wherein a thickness of the electrolyte membrane is about 15 ?m or less.Type: ApplicationFiled: February 12, 2021Publication date: March 16, 2023Applicants: Board of Trustees of the Leland Stanford Junior University, Volkswagen AktiengesellschaftInventors: Friedrich B. Prinz, Timothy Goh, Shicheng Xu, Zhaoxuan Wang, Soonwook Hong, Yongmin Kim, Samuel Dull, Dong Un Lee, Thomas Francisco Jaramillo, Thomas Schladt, Gerold Huebner, Jonathan Müller, Glavas Vedran
