ACTIVE CATHODES FOR SUPER-HIGH POWER DENSITY SOLID OXIDE FUEL CELLS THROUGH SPACE CHARGE EFFECTS
Description:
This report summarizes the work done during the eleventh quarter of the project. Conductivity relaxation experiments were conducted on porous La{sub 0.5}Sr{sub 0.5}CoO{sub (3-{delta})} (LSC50) samples over a temperature range from 350 to 750 C, and over an oxygen partial pressure, p{sub O{sub 2}}, switch between 0.04 and 0.06 atm in order to determine the surface exchange coefficient, k{sub chem}. The normalized conductivity data could be fitted to a first order kinetic equation. The time const…
