Abstract :In this study use of a reversible solid oxide fuel cell for co-electrolysis of steam and carbon dioxide is investigated using zero and multi-dimensional modeling tools. A zero-dimensional model is taken into account as the base model and applied to a single-cell system. Dimensions of the cell is used for the zero-dimensional model to provide a base for the multi-dimensional performance enhancement of the cell at micro to macro scales. An optimal current density is available at slightly lower than 1000 A/m2 to provide low overpotentials and higher efficiency. Maximum reachable cell efficiency in this case is about 75%.
