ABSTRACT In the near future, some fuel cell systems could be an accessible and attractive alternative to conventional electricity generation and vehicle drives. The polymer electrolyte membrane (interchangeably called proton exchange membrane, PEM) fuel cell systems can be made in mW to kW capacities; hence a wide range of applications can be covered by this type of fuel cell. This is a major advantage of this type of fuel cell, because once the technology was developed it can be more or less easily scaled up or down for various applications. PEM fuel cell has attracted a great deal of attention as a potential power source for automobile and stationary applications due to its low temperature of operation, high power density and high energy conversion efficiency. Great progress has been made over the past twenty years in the development of PEM fuel cell technology. However, there are still several technical challenges that need to be addressed before commercialization of PEM fuel cell. In this study, the dynamics of a polymer electrolyte membrane fuel cell system is modelled, simulated and presented. Matlab –Simulink TM is used for the modeling and simulation of the fuel cell system. The fuel cell system model consists of the dynamics of reactant flow, fuel cell model and power conditioning units. Also, characteristic of 1.2 W PEM fuel cell system is obtained by experiments. Simulation and experimental results are presented in this paper. The analyses of grid connected or stand alone applications of PEM fuel cell generator system can be achieved with this dynamic simulation model.

    ABSTRACT: In the recent years there is an increasing interest in fuel cell technology and fuel cells have reached a high development status. This development was mostly advanced by the automotive industry and residential applications, because fuel cells are suitable to substitute the fossil fuels and also to provide an environment friendly propulsion. But there is also a growing market for stationary fuel cell applications (cogeneration of heat and power, and as a substitute for batteries in portable devices). In this study, application areas of the fuel cells were classified and investigated separately. In addition to the last developments and trend on the fuel cell technology were analyzed. Otherwise, the new application areas of the fuel cells were discover red and then economic advantages which usage of the fuel cell will provide were disputed.

    ABSTRACT: The paper is to propose a multi-input power converter (MIPC) for hybrid photovoltaic (PV) array, wind turbine (WT), fuel cell (FC) and battery storage (BT) connected AC grid network. The aim is to simplify the power system and reduce the cost. The proposed MIPC consists of a dc-dc converter and a dc-ac inverter. The output power characteristics of the PV array, WT and FC are introduced. The perturbation and observation (P&O) method is mainly used to accomplish the maximum power point tracking (MPPT) algorithm for PV array and WT sources and set FC operation power on optimal range by proton exchange membrane fuel cell (PEMFC). The MIPC is capable to operate in five modes; first to third modes occur when the power only from either renewable energy (RE) sources, fourth mode happens when power is demanded from all RE sources and finally when no power are available from all RE sources. The proposed system has been simulated by Matlab/Simulink software and the results are discussed in details.

    ABSTRACT: This paper presents a novel comparative study on fuel cells (FCs) technologies, its modeling and effect of important parameters on the performance of various types of fuel cells and power management schemes. Firstly, this paper presents a comprehensive review of various FCs technologies with their working principle, efficiency, operating parameters, advantages/disadvantages and applications. Secondly, the mathematical analysis of various FCs has been investigated, which is required for MATLAB simulation of FCs. The influences of various operating parameters such as temperature, reactant flow pressure and membrane resistance are considered to investigate the dynamic behavior of FCs. Thirdly, various control schemes of power management e.g., current, voltage, power and reactants flow pressure based control schemes are proposed with simple and easy to implement PI controller for a phosphoric acid fuel cell (PAFC) operation in this paper. These control mechanisms can be utilized for power management schemes. The proposed model of PAFC along with these control schemes is realized in the MATLAB/Simulink environment. The performance of a PAFC system along with these proposed control is found to be satisfactory even under dynamic conditions. The study can be broadly helpful to select and set the various parameters for the development of a FC based application.
