   Keywords : SOCs; SOECs; SOFCs; multiphysics; modeling; three dimensional; transport phenomena; electrochemical reactions; overpotentials; potentials; boundary conditions; validation; experimental data; degradation; carbon deposition; steam; hydrogen; carbon dioxide; carbon monoxide; carbon activity;

   Abstract : Solid oxide electrochemical cells (SOCs) are considered a highly promising technology for providing efficient, sustainable and economic conversion between chemical energy and electrical energy. SOCs can be operated as fuel cells, where electric power is obtained from fossil or non-fossil hydrocarbon fuels depending on the origin or as electrolysis cells, whereby using electrical energy from renewable sources like wind or solar, chemical energy can be stored as fuels.
