Methods and compositions for electrocatalytic surface nanoionics for enhancing durability and performance of solid oxide cells

Abstract

In one aspect, the disclosure relates to ALD-coated cells comprising a conformal ultra-thin nanocomposite comprising Pt and CoOx on a LSCF/SDC cathode backbone. In a further aspect, the ALD-coated cells comprising an ultra-thin nanocomposite comprising Pt and CoOx on a LSCF/SDC cathode backbone are prepared using a disclosed Atomic Layer Deposition (ALD) coating method. In a still further aspect, the disclosed ALD-coated cells comprise a heterogeneous coating layer comprising subjacent discrete Pt nanoparticles capped with superjacent fully dense conformal CoOx layer. In a yet further aspect, the performance of the disclosed ALD-coated cells is improved compared to baseline cells lacking the disclosed ALD coating on a LSCF/SDC cathod backbone. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
