“…The voltage obtained from equation (4) is open circuit voltage and the normal operative voltage gets reduced from that due to the activation ( ), concentration ( ) and resistive ( ) losses of the FC. Thus, the output voltage ( ) can be expressed as equation (5) [16].…”

Alternative energy technologies are being popular for power generation applications nowadays. Among others, Fuel cell (FC) technology is quite popular. However, the FC unit is costly and vulnerable to any disturbances in input parameters. Thus, to perform research and experimentation, Fuel cell emulators (FCE) can be useful. FCEs can replicate actual FC behavior in different operating conditions. Thus, by using it the application area can be determined. In this study, a FCE system is modelled using MATLAB/Simulink®. The FCE system consists of a buck DC-DC converter and a proportional integral (PI) based controller incorporating an electrochemical model of proton exchange membrane fuel cell (PEMFC). The PEMFC model is used to generate reference voltage of the controller which takes the load current as a requirement. The characteristics are compared with Ballard Mark V 5kW PEMFC stack specifications obtained from the datasheet. The results show that the FCE system is a suitable replacement of real PEMFC stack and can be used for research and development purpose.

“…The main challenge of FCE system is to emulate the fuel cell characteristics. Several emulators use electrical circuit representation of the FC model, while others use electrochemical model to extract the characteristics of FC [15], [16]. The initial FCEs include only the steady state behaviour [17].…”

“…The fuel is typically hydrogen (H 2 ), and the oxidant is usually the oxygen (O 2 ) from air. The O 2 or air continuously passes over the cathode and the H 2 passes over the anode to generate electricity, byproduct heat and water [6]. The cathode flooding with H 2 /air increases the O 2 mass transfer resistance in the electrode and the degrees of hysteresis in the polarization and power density with H 2 /air become worse than those with H 2 /O 2 .…”

It is important for fuel cell to become flexible in order to accommodate the situations of application areas for reducing costs and expanding coverage. Scale ups in series and parallel to 1-kW class proton exchange membrane (PEM) fuel cell stack are characterized experimentally with oxidant as air and oxygen. Through a serial scaled-up 4-cell stack with an active area of 25 cm 2 and a parallel scaled-up single cell with an active area of 100 cm 2 , respectively, the 1-kW class 20-cell stack with an active area of 150 cm 2 per cell is scaled up from the basic unit cell with maintaining their performances. The polarization and power curves of the 1-kW class PEM fuel cell stack with the reactants H 2 /air and H 2 /O 2 are evaluated. Sufficient power of the PEM fuel cell can operate at flexible nominal current of 40-80 A and nominal voltage of 12-15 V for providing durability and balance between cells. The 1-kW class PEM fuel cell stack is characterized through the comparison of cell voltage differences utilizing H 2 /air and H 2 /O 2 . Both cell voltages with H 2 /air and H 2 /O 2 follow well the one-twentieth of the responding stack voltages with the small difference.

“…In [8], a fuel cell real-time simulator oriented to evaluate the performance of DC/DC and DC/AC converters was presented. Similarly, an emulator based on electrical circuit model was presented in [9]; a programmable DC power supply was used to generate the open circuit voltage. All of these contributions focused on emulating the behaviors of the fuel cell systems.…”

This article presents a study of a proton exchange membrane fuel cell system taking into account the fuel starvation phenomenon; this phenomenon causes serious problems when the load changes rapidly. Therefore, oxygen and hydrogen excess ratios are two important issues that should be controlled in the proton exchange membrane fuel cell. To verify the influences of this phenomenon on the fuel cell performances, a proton exchange membrane fuel cell emulator system is realized with dSpace (Cedex, France). In addition, a supercapacitor as an energy storage system is proposed as another solution to prevent this phenomenon, improve performance, and increase lifetime. Experimental results illustrate that the proposed emulator is an excellent tool for testing and experimenting energy storage systems and electronic devices for proton exchange membrane fuel cell applications and determine their impact on the fuel cell characteristics.
