Abstract
A fuel cell device has a composite particle electrode () formed using particles () having a combination of ion conductor material, electron conductor material, and catalyst material. Each composite particle () is preferably formed to have a substantially spherical outer layer () of ion conductor material () with conductive and catalyst particles () are dispersed throughout the outer layer (). An array of composite particles () is layered in a substantially structured or ordered manner on a membrane support structure () to form the fuel cell electrode. A fuel cell electrode so formed has interstitial gaps between the composite particles that result in a structure permeable to oxygen and other fluids.
