AI Technical Summary
There is a need to improve reaction efficiency in the electrode layers of solid oxide cells, particularly in the fuel electrode, to enhance the performance of solid oxide fuel cells and water electrolysis cells.
Incorporating electron-conductive needle-shaped particles made of an Fe-Ni-based alloy into the fuel electrode, with a major axis being at least 1.5 times the length of the minor axis, and combining these particles with an ion conductor such as gadolinia-doped ceria or yttria-stabilized zirconia, increases the contact area and catalytic activity, thereby enhancing the reactivity of the electrode layer.
This configuration improves the reactivity and performance of the solid oxide cell, particularly in water electrolysis mode, by increasing current density and reducing irreversible loss.
