    Experimental study of the static behaviour of the PEM fuel cell
    (IPCO, 2017) Nedjem Eddine Benchouia; Bouziane Mahmah
    This work proposes and justifies an easy electric model of a power generation system based on a PEM fuel cell, the H-Tec PEM Power Module of 1.2W. This model has been developed by means of experimental data obtained in our laboratory.

    Fuel Cells and Hydrogen Storage: Challenges Facing Vehicle Manufacturers
    (IPCO, 2017)
    The main challenge of our time is to find renewable energy sources that meet the needs of society. Nevertheless, energy must meet several criteria such as abundance, ease, and speed of use, but also the cost of production which must be low. In addition, the aspect of "clean and renewable energy" is also to be taken seriously. Today, fuel cells are a magnet for researchers because they have many advantages. First of all, these batteries have the capacity to produce a significant amount of electricity, water, and heat. In addition, the reagents of the battery are the oxygen naturally present in the atmosphere and the di-hydrogen that needs to be produced. Its production is therefore a major stake for the installation of the fuel cell. Many hopes rest on the fuel cell. As we have seen, it is one of the energy sources that have the most to become and application area. With a relatively high efficiency, and zero pollutant emissions, this fuel cell has many other advantages such as the variety of batteries that can be adapted to all current needs such as transportation, global electricity generation, or digital. Because of the benefits that flow from its use as an automobile fuel, hydrogen is expected to take precedence over other synthetic fuels in the not-too-distant future.

    Determination of the predictive Reliability for PEMFC system
    (IPCO, 2015) Nedjem Eddine Benchouia; Lakhdar Khochemane; Belgacem Madi
    Today reliability is one of the serious requirements of fuel cell systems, and their associated cost in all applications, in general, and automotive applications, in particular when the power requirement is scaled up, is still unclear. Therefore, increasing cell lifetimes and membrane electrode assembly (MEA) durability is the technical advance that may be expected so that we can have a remarkable tendency of decreasing fuel cell costs with a significant increase in global systems safety, that best meet customer requirements. Our contribution, in this paper, focuses on the simulation method of the “Monte Carlo” over the entire reliability calculation for the PEMFC system, with the integration of the most critical elements of them and the proposition of the contrivances for their modifications, in the objective to predict the lifetime and failure rate of a system by reliability calculations: a problem formulation is given, reliability calculations of PEMFC are defined and a reliability estimation methodology is developed. We did obtain, however, some results that can help us in the prediction reliability way at the design

    Synthesis of a control law for stabilization nonlinear systems: results and discussions
    (IPCO, 2015) Nedjem Eddine Benchouia; Belgacem Madi; HichamTebbikh; Mounir Benadja
    Dans ce papier, nous avons étudié le problème de stabilisation des systèmes non linéaires de la forme x= F(x)+Bu au voisinage d'une position d'équilibre de F(x). La stratégie consiste en l'application de la théorie des variétés centrales, permettant de passer d'un système complexe à un système simple, de dimension réduit, facile à étudier. Des exemples illustratifs ont été discutés et valider numériquement afin de synthétiser une loi de commande stabilisatrice pour tels systèmes.

    Analysis and Characterization of PEMFC Power Systems with Bond Graph
    (2013-11) Nedjem Eddine Benchouia; Elias Hadjadj Aoual; Lakhdar Khochemane; Bouziane.Mahmah
    This paper addresses the problem of bond graph methodology as a graphical approach for modeling fuel cell systems. The system consists of a Proton Exchange Membrane Fuel Cell (PEMFC) stack and an interleaved boost converter. Simulation results illustrate the simplified system response obtained using the implementation of the governing equations in MATLAB/Simulink or a bond graph

    An adaptive fuzzy logic controller (AFLC) for PEMFC fuel cell
    (www.elsevier.com/locate/he, 2015) Nedjem-Eddine Benchouia; Abdallah Derghal; Bouziane Mahmah; Belgacem Madi; Lakhdar Khochemane; Elias Hadjadj Aoul
    Among the various fuel cell technologies available for use in vehicular systems, the Proton Exchange Membrane Fuel Cell (PEMFC) has drawn the most attention due to its simplicity, viability, higher power density, and operation at lower temperatures. Due to these features, PEMFC is considered to be the most suitable technology for vehicular systems, industry, and other applications. As fuel cells are likely to be used in many future applications, great efforts have recently been made for their comprehension and design. This paper focuses on a 1.2WPEM fuel cell unit and develops the models of stack voltage and stack power. While the PEM fuel cell is a nonlinear process, it is very suitable to use fuzzy control to solve the control issue of the fuel cell. The stack output power can be controlled to a given value by using a variable universe fuzzy controller by controlling the input gas flow rate. In this paper, an FLC controller has been designed to control the voltage in the presence of fluctuations. The results of the implementation of this designed FLC controller on a dynamic electrochemical model of a small size 1.2 W, PEM fuel cell have been simulated by MATLAB Simulink and compared with a traditional PID controller. Simulation results show that good control effects can be achieved by using the adaptive fuzzy control system.

    Bond graph modeling approach development for fuel cell PEMFC systems
    (www.elsevier.com/locate/he, 2014-09-14) Nedjem Eddine Benchouia; Elias Hadjadj Aoul; Lakhdar Khochemane; Bouziane Mahmah
    This paper addresses the problem of bond graph methodology as a graphical approach for modeling fuel cell systems. The system consists of a Proton Exchange Membrane Fuel Cell (PEMFC) stack, an interleaved boost converter, battery pack connected via a buck converter. Simulation results illustrate the simplified system response obtained using implementation of the governing equations in MATLAB/Simulink and is compared with a bond graph implementation in the simulation program 20-sim.
