Silver incorporation into cathodes for solid oxide fuel cells operating at intermediate temperature
Silver incorporation into cathodes for solid oxide fuel cells operating at intermediate temperature
Silver (Ag) at 0.1 - 2.0 wt% was incorporated into cathodes for solid oxide fuel cells as a catalyst for oxygen reduction. A novel processing route for Ag incorporation ensuring a very homogeneous Ag ion distribution is presented. From the results of X-ray powder diffraction it can be concluded that...

Silver (Ag) at 0.1 - 2.0 wt% was incorporated into cathodes for solid oxide fuel cells as a catalyst for oxygen reduction. A novel processing route for Ag incorporation ensuring a very homogeneous Ag ion distribution is presented. From the results of X-ray powder diffraction it can be concluded that the La0.65Sr0.3MnO3-delta perovskite phase is already formed at 900 degreesC. The solubility of Ag in the crystal lattice in this type of perovskite was below 1 wt%. The electrochemical tests of these materials show that there is only a slight catalytic effect of Ag. Scanning electron microscopy reveals a low mechanical contact of the cathode grains to the electrolyte due to the low cathode sintering temperature that was chosen. |
