    Abstract: Catalyst material comprising nanoparticles dispersed within a metal oxide layer, the metal oxide layer comprises metal oxide comprising at least one metal cation, wherein the nanoparticles comprise Pt, wherein the nanoparticles comprise less than 10 atom % of oxygen, and wherein the metal oxide layer has an average thickness not greater than 50 nanometers. The catalyst material comprising nanoparticles dispersed within a metal oxide layer can be converted, for example, to nanoporous catalyst layer comprising nanoparticles fused together, wherein the nanoparticles comprise Pt, wherein the nanoparticles comprise less than 10 atom % of oxygen, and wherein the layer has an average thickness not greater than 50 nanometers. The nanoporous catalyst layer is useful, for example, in fuel cell membrane electrode assemblies.

    Abstract: A fuel cell electrode layer may include a catalyst, an electronic conductor, and an ionic conductor. Within the electrode layer are a plurality of electronic conductor rich networks and a plurality of ionic conductor rich networks that are interspersed with the electronic conductor rich networks. A volume ratio of the ionic conductor to the electronic conductor is greater in the ionic conductor rich networks than in the electronic conductor rich networks. During operation of a fuel cell that includes the electrode layer, conduction of electrons occurs predominantly within the electronic conductor rich networks and conduction of ions occurs predominantly within the ionic conductor rich networks.
