Abstract: 

A modification of the phase inversion method that enables high-precision control of the geometric parameters (diameter, wall thickness, and degree of alignment) of anode microtubular substrates of solid oxide fuel cells was proposed. Due to unique properties of the phase inversion process, which occurs simultaneously with solvent melting, anode microtubes with increased porosity and gas permeability were obtained compared to the microtubes obtained by traditional phase inversion extrusion method.
