Abstract
We present a novel cathode fabrication technique for improved performance and production efficiency of SOFCs based on an infiltration method assisted by layer-by-layer (LbL) assembly of polyelectrolytes. Preparation of the electrode with LbL-assisted infiltration leads to a 6.5-fold reduction in the electrode fabrication time while providing uniform and small formation of Pr0.7Sr0.3CoO3-δ (PSC) particles on the electrode. The increased surface area by 24.5% and number of active sites of the prepared electrode exhibits superior electrochemical performance up to 36.1% while preserving the electrical properties of the electrode. Because of its versatility and tenability, the LbL-assisted infiltration process may become a new route for fabrication of composite electrodes for other energy storage and conversion devices.
