| Research Abstract |
We have investigated novel high performance, durable electrodes in a solid oxide electrolysis cell(SOEC) for hydrogen production/power generation(solid oxide fuel cell, SOFC, mode). We have succeded in preparing mixed conducting samaria-or gadolinina-doped ceria with highly dispersed Ni or Ni-Co nanoparticle catalysts. The performance of Ni-Co/SDC hydrogen electrode was found to be improved with increasing ionic conductivity in the solid oxide electrolyte. We also found that(Sr_<1-x> Ce_x) MnO_<3±δ> exhibited a good perforamnce as the SOFC cathode.
