Title: Core-Shell Heterostructures as Solid Oxide Fuel Cell Electrodes

Abstract

The goals of the project are to synthesize and deploy core-shell heterostructures as solid oxide fuel cell (SOFC) cathodes which exhibit high oxygen reduction rates at lower operating temperatures resulting in high performance at lower operating temperature and simultaneously exhibit longterm resistance to Cr-impurity attack induced performance degradation. An ancillary objective is to eliminate cumbersome, multiple infiltration steps in the cathode to achieve high performance. The expected outcomes are (1) a novel, environmentally benign, and inexpensive synthesis tool for synthesizing complex cathode powders, scalable to high volumes; (2) decrease in energy expenditure during synthesis of cathode powders; (3) up to a factor of 1.5 improvement in maximum power density of single cells at 700ºC; and (4) significant improvements in cell performance degradation rates down to 0.02%/1000 h.
