Title: John C. Doyle: Innovator in Membrane Electrode Assembly Technology
Introduction
John C. Doyle is a notable inventor based in Bergen, NY (US), recognized for his contributions to the field of fuel cell technology. With a total of 2 patents, he has developed innovative techniques that enhance the performance and durability of membrane electrode assemblies (MEAs).
Latest Patents
Doyle's latest patents include groundbreaking methods for fabricating MEAs. One of his patents describes a membrane electrode assembly prepared by direct spray of catalyst to membrane. This technique involves providing a polymer electrolyte proton conducting membrane and spraying a catalyst ink directly onto the membrane to form a catalyst layer. The catalyst ink is formulated with a specific ionomer to carbon ratio, such as 0.8/1, to achieve optimal fuel cell performance. In another embodiment, the patent addresses scenarios where the catalyst ink contains insufficient ionomer, affecting the desired performance. To rectify this, an ionomer layer is sprayed on the membrane prior to the catalyst layer, ensuring the correct final ionomer to carbon ratio.
Another significant patent by Doyle focuses on durable membrane electrode assembly catalyst-coated diffusion media with no lamination to the membrane. This innovative technique fabricates an MEA as a catalyst-coated diffusion media (CCDM). The MEA comprises a diffusion media layer with a microporous layer, onto which a catalyst layer is deposited. An ionomer layer is then sprayed on the catalyst layer. A perfluorinated membrane is sandwiched between two CCDMs, with the ionomer spray layers facing the membrane, enhancing the overall efficiency of the fuel cell.
