9.13 Nafion 117 has a conductivity of approximately 0.1 S/cm and a thickness of approx- imately 200µm. You have developed a solid-oxide electrolyte (O2- conducting) with the following properties: • Carrier concentration c = 10-3 mol/cm³ Eact 0.6 eV • Do = 10- cm²/s You want to operate your SOFC electrolyte at 400°C and to have a comparable ASR to the Nafion 117 membrane. What thickness must your solid membrane be to have the same ASR as Nafion 117?
