Abstract
A method of making a fuel cell includes the following steps. A pattern is placed on a base surface to create a predetermined topography on the base surface. An anode layer, a cathode layer and/or an electrolyte layer is/are deposited over the pattern. Areas of higher topography are removed from areas of lower topography using chemical mechanical planarization to form a predetermined fuel cell structure.
