Abstract Scope |
Utilizing additive manufacturing for the advanced manufacturing of electrodes for use within solid oxide fuel cells (SOFCs) offers the possibility to control the microstructure and composition with resolutions of less than 20 µm. Ultrasonic atomizer spray nozzle technology accompanied with a flexible automation system has been developed to evaluate variables associated with the chemistry, particle size, and porosity architecture of the electrodes. The electrical and mechanical properties of the respective electrodes were characterized via Electrochemical Impedance Spectroscopy (EIS) and Scanning Electron Microscopy (SEM) to properly evaluate variables associated with the additive manufacturing system. Demonstrations of manufacturing electrodes with changes in the microstructure within multiple dimensions was also investigated to exhibit the potential that additive manufacturing has to fabricate highly customizable electrodes. Development of the system to manufacture a complete SOFC through a controlled automated process was also studied. |
