Solid oxide fuel cells fueled with reduced Fe/Ti oxide

摘要: For the first time, a Fe–Ti–O containing pellet, viable chemical looping particle, was used as solid fuel for direct contact with Ni/YSZ anode surface of oxide cell. A maximum power density 97 mW cm−2, corresponding to 84% that in H2 fuel, produced using an inert Ar gas environment at 750 °C. The pellets were able generate stable electricity under repeated electrochemical oxidation and hydrogen reduction cycles. Temperature-programmed oxidation–reduction coupled infrared spectroscopic studies revealed pellet followed shrinking core model; progressive-conversion model. ability on can be attributed its low resistivity (<17 Ω cm) which allows electrons transport from sites surface. This study demonstrates coupling SOFC external reducer Fe–Ti–O, oxygen carrier, is good candidate generation.
