Abstract
The disclosure provides a porous metal substrate structure with high gas permeability and redox stability for a SOFC and the fabrication process thereof, the porous metal substrate structure comprising: a porous metal plate composed of first metal particles; and a porous metal film composed of second metal particles and formed on the porous metal plate; wherein the porous metal plate has a thickness more than the porous metal film, and the first metal particle has a size more than the second metal particle. Further, a porous shell containing Fe is formed on the surface of each metal particle by impregnating a solution containing Fe in a high temperature sintering process of reducing or vacuum atmosphere, and the oxidation and reduction processes. The substrate uses the porous shells containing Fe particles to absorb the leakage oxygen.
