This research forms a basis for the process of quantifying and simulating the reactions occurring within a Solid Oxide Fuel-Assisted Electrolysis Cell and the results emanating from it. This relatively new alternative application within the known SOFC is a subject of great interest. Initial laboratory tests predict it's highly efficient hydrogen production ability. A summation of previous works will be followed by a detailed explanation of the theory behind the SOFEC. In the whole report, comparisons will constantly be made with a SOFC, in an attempt to better understand the processes involved. This theoretical knowledge is expanded with a mathematical description of the internal processes involving the cell voltage, current density, resistance and voltage drop. These variables are linked together through a single equation. Based on the known SOFC equation, a SOFEC variant is proposed. This is done by breaking down the steps performed within Cycle Tempo. These are analyzed individually, an alterations are made. Afterwards, the actual programming code is analyzed, and all alterations are summarized. They are changed according to the proposed theory. With a working program, the results are finally analyzed and compared to the theory. This is followed by a chapter covering explaining the basics of the hydrogen economy. The advantages and problems occurring from this are summarized and a possible future implementation of the SOFEC is given. The report end with a conclusion and recommendations.
