Abstract
The vital importance of mechanical engineering approaches has been increasingly acknowledged in the research and development
of electrochemical devices such as fuel cells and batteries because the coupled multi-species transport in their complex multicomponent
structures is a key to explaining their macroscopic performance. In this article, novel fabrication techniques for solid
oxide fuel cells（ SOFCs） to realize unique electrode microstructure with improved reaction and transport characteristics are
overviewed with their theoretical backgrounds. The techniques include the meso-patterning on the electrode-electrolyte interface
that increases the active reaction thickness, the nano-particle infiltration technique that enhances the electrochemical activity of the
electrode without sacrificing the gas transport property, and the phase-inversion technique that introduces anisotropic pore structures
in the electrode with significantly high gas transport properties.
