In the last decades, the interest in solid oxide fuel cells has been increasing and its use is becoming more frequent for the generation of stationary electric power. At the same time, the existing software used to analyze the behavior of these cells does not present a complete simulation platform for such a study. With a computational modeling that allows a performance analysis under various operating conditions, it is possible to find the optimal point of operation of the cell. This work intends to fill this gap by presenting a complete modeling of a solid oxide fuel cell developed for Aspen Plus software. The result of this modeling allowed to obtain the values of anodic recirculation and oxygen flow for the anode, 5% and 27% respectively, which reached a power of 180kW delivered by the cell without the need to increase the fuel flow. It can be concluded that SOFC modeling it is possible to find the optimal point of operation, without the need to perform tests on the cell and thus avoid its wear.
