  • Patent number: 10826076
    Abstract: Disclosed herein are embodiments of a patterned electrode comprising regions of catalyst and segregating regions that separate the regions of catalyst. The segregating regions may be regions of non-catalytic material. The catalyst regions may correspond to the channels of a flow field. The electrode provides improved fuel cell performance, particularly at high current densities. The electrode may be for all suitable applications, such as in a membrane electrode assembly and/or a fuel cell. Also disclosed is a method for making the patterned electrode. The method may comprise using masks to apply the catalyst and non-catalyst material to a substrate.

  • Publication number: 20200321626
    Abstract: A polymer electrolyte fuel cell (PEFC), comprises a first electrode and a second electrode, wherein the first electrode includes a coaxial nanowire electrode. In some embodiments, the coaxial nanowire electrode comprises a plurality of ionomer nanowires, and a catalyst coating that coats at least part of the ionomer nanowires. Moreover, in some embodiments, a nanowire of the plurality of ionomer nanowires and a section of the catalyst coating that coats the nanowire form two coaxial cylinders.
