This work provides discussion on the subject of deriving tortuosity from a saturation current and a mass transport model. In the conducted research an anode-supported solid oxide fuel cell (SOFC) with Nickel/Yttria-Stabilized Zirconia (Ni/YSZ) anode, Yttria-Stabilized Zirconia (YSZ) electrolyte, and...
