In the fabrication of Solid Oxide Fuel Cells (SOFC) and Electrolysis Cells (SOEC), a NiO (Nickel Oxide) slurry is the liquid suspension used to deposit the precursor for the hydrogen electrode. While most industrial applications use a composite NiO/YSZ or NiO/GDC slurry, pure NiO slurries are often used in research for infiltration techniques or as a contact layer to improve current collection. The primary function of the NiO slurry is to provide a high-surface-area coating that, upon reduction to metallic Nickel (Ni), becomes the catalyst for hydrogen oxidation or water splitting.
The multi-components of NiO slurry are:
Functional Roles of NiO in the Slurry: (1) Catalytic Precursor: NiO is a ceramic insulator. It must be reduced in situ using hydrogen gas (NiO + H2 → Ni + H2O) to become the active catalyst. (2) Porosity Generation: Metallic Ni has a molar volume ~40% smaller than NiO. This volume contraction during the first run of the cell creates the micro-porosity necessary for gas molecules to reach the reaction sites. (3) Electronic Connectivity: Once reduced, the Ni particles must touch each other to form a "percolation network" that carries electrons from the reaction site to the external circuit.
