High-Performance Electrodes for Medium-Temperature Solid Oxide Fuel Cells-Mixed Conducting Ceria-Based Anode with Highly-Dispersed NI Electrocatalysts

摘要

It is desirable to operate solid oxide fuel cells (SOFCs) at a medium temperature (approx 800 deg C) to overcome many serious problems such as a degradation of materials and a limited choice of materials,etc.Besides a reduction of ohmic loss in the solid electrolytes,high performance electrodes must be developed because the electrode reaction rates slow down at such temperatures.
