A novel proton exchange membrane fuel cell with nanostructured components with higher precious metal utilization rate at the electrodes, higher power density, and lower cost. Aligned arrays of carbon nanotubes, either single wall or multiwall, are prepared by catalyzed chemical vapor deposition (CVD), or plasma assisted CVD and used as support for catalyst. Solubilized perfluorosulfonate ionomer membrane is incorporated into the spare space between nanotubes to form a 4-phase boundary of gas, metal, proton conductor, and electron conductor. By assembling the as-prepared electrodes with perfluorosulfonate ionomer membrane, backing layers and electron collectors, proton exchange membrane fuel cells are developed.

A method is proposed for providing a content page in an application. In the method, a media item is generated, and the media item is associated with respective resources in a resource list that is received from a resource provider. The media item is presented in the application. A content page is caused to be displayed in response to detecting an interaction event of a user of the application with the media item, the content page including respective content items for the respective resources. Therefore, the media item and the content page are generated and displayed in an automatic way for the one or more resource providers without any label work from the resource providers.
