One possible new renewable source that is emerging as a promising technology is the fuel cell. The ‘F.C’ is an electrochemical system that transfers the chemical power of a redox response into electrical energy with simultaneous production of water and heat. In fact, there are numerous kinds of fuel cells; in our work we are interested in studying the solid oxide fuel cellSOFC. In the context of this work, a modeling tool has been implemented SOFCs to the analogy between the electrical, thermal and chemical domains; this way of proceeding constitutes a simple, evolutionary and efficient tool. Using this modeling, a simulation was carried out in order to obtain the dissimilar characteristics and the impact of the studied parameters on the performance of the SOFC fuel cell.

INTRODUCTION In recent decades, solid oxide fuel cell SOFCs cells have attracted a lot of attention, owing to their potential uses as stationary power producers and mobility (ground, marine, air). The great energy conversion efficiency and minimal hazardous emission levels of SOFCs make them appealing (only the CO2 released by the hydrogen production process is a concern). Modularity, fuel flexibility, and minimal noise are among the other benefits [1]-[3]. Furthermore, high operating temperatures afford good features, such as potential utilize of SOFCs in extremely proficient cogeneration applications. Solid oxide fuel cells are also appropriate for internally reforming the fuel (e.g.natural-gas, propane, methanol, gasoline, and diesel), as a result making it doable to stay away from the acceptance of both highly sophisticated, expensive outside reformer and to remove the complexities from fuel storage [4]. The giant confronts to promote the dispersion of SOFC-based energy conversion systems are mostly connected to manufacture costs and permanence. The accomplishments of these objectives shall definitely contribute to upholding the technology and lastly beginning a mass production stage. Above and beyond expenses and performance, long-standing steadiness is a crucial condition for the marketable application of the SOFC technology [5], [6]. The hydrogen vector, namely fuel cells and electrolysis (to make hydrogen), also offers promising potential for these large-scale storage applications, where conventional batteries play a key role. As a result, the storage solution will be multi-system, and the electrical study of the association of many sources of energy - hybridization - will take on new significance in this context. Solid oxide fuel cells (SOFC) are electrochemical devices that allow chemical energy to be converted into electrical energy. The premise is straightforward: water and electricity are produced from a fuel like hydrogen and an oxidant like oxygen.
