Development of planar geometry solid oxide fuel cells
Abstract
The progress made towards the development of planar geometry SOFCs is summarized. Graded composite electrolytes, suitable for use in a fuel cell, were developed using two phase Bi2O3 solid solutions heterogeneously doped with ZrO2. Efforts are underway to minimize microstructural voids at heterogeneous interfaces via alternative processing techniques. Electrode/electrolyte interface characterization studies are in progress. Electrode performance was improved at planar SOFC electrolyte interfaces.
