Abstract Scope |
A solid oxide electrolysis cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas and oxygen. Electrode microstructure plays an important role in the performance of solid oxide fuel and electrolysis cells, as it determines the reactive surface sites. The most important parameters include grain size, grain size distribution, porosity, tortuosity, and electrode thickness that are highly attached to the production technique of the material. This work focuses on the effect of microwave (MW), and ultra-fast high-temperature sintering (UHS) techniques on the surface microstructure and electrochemical characteristics. The effect of input power, heating rate, sample furniture/setter and insulation materials, and processing atmosphere on the final microstructure and electrochemical properties of the electrode and electrolyte materials were determined by Scanning Electron Microscopy (SEM), I-V curves, and Electrochemical Impedance Spectroscopy (EIS). |
