Solid Oxide Fuel Cell (SOFC)
-
Electrolyte: ceramic(yttria stabilized zirconia, YSZ, ZrO2 doped with Y2O3)
-
Anode: NI mixed with YSZ
-
Cathode: Lanthanum strontium manganite(LSM, (La,Sr)MnO3)
-
Operating: 500o-1000oC
-
Efficiency: 50%-60%
-
Issues: long start up time, corrosion, material challenges, durability
-
Cathode: I/202 + 2w- = O2-
-
Anode: H2 + O2- = H2O + 2e-
-
Overall: H2 + I/2O2 = H2O
