Abstract:
1. An apparatus for electrostatic spray deposition of an electrolyte material on a solid oxide fuel cell component, the apparatus comprising: a source containing a solution including an electrolyte material precursor and containing a particulate form of the electrolyte material; a nozzle having a passage in communication with the source and with an opening at a discharge end of the nozzle; a collar attached to and positioned at a distance from the discharge end of the nozzle; and a voltage source applying a potential difference between the nozzle and a substrate surface of the solid oxide fuel cell component; wherein a potential of a first polarity is applied to the nozzle and wherein a potential of a second polarity, opposite the first polarity, is applied to the substrate wherein the collar has an inside surface facing the nozzle, and at least a portion of the inside surface diverges in a downstream flow direction of the solution.
