“…With the efficiency of the battery (90%), its output energy (E o,BA ) is calculated, which is also shown in Table 1. This value should be equal to the output energy of the fuel cell (E o,EL-FC ), considering the efficiency of the electrolyzer and fuel cell [28][29][30][31][32][33]. For that purpose, an energy balance is now performed (as shown in Figure 4) to finally calculate the value of the input energy of the electrolyzer (E i,EL ).…”

The use of renewable energy and hydrogen technology is a sustainable solution for the intermittent feature of renewable energies. Hence, the aim of the present work is to design a self-sufficient system for a one-family house by coupling a solar photovoltaic array and an anion exchange membrane water electrolyzer (AEMWE). The first step is the selection of the photovoltaic panel by using PV-SYST 7.0 software. Then, the hydrogen production system is calculated by coupling the electrolyzer and photovoltaic panel current–potential curves. A fuel cell is selected to use the hydrogen produced when solar energy is not available. Finally, the hydrogen storage tank is also estimated to store hydrogen for a design basis of four consecutive cloudy days according to the hydrogen consumption of the fuel cell. The whole system is designed by a simple procedure for a specific location in Ciudad Real (Spain) for January, which is known as the coldest month of the year. The simple procedure described in this work could be used elsewhere and demonstrated that the hydrogen production at low scale is a suitable technology to use renewable energy for self-energy supporting in a residential application without any connection to the grid.

“…It is also regarded as a new type of green power generation device that is expected to replace conventional power generation technology due to its high power density and energy conversion efficiency. [7][8][9][10][11] During the operation of PEMFC, hydrogen and oxygen enter the anode and cathode of the cell through the flow channel of bipolar plate (BPP) and then pass through the gas diffusion layer to reach the catalyst layer for electrochemical reaction. To ensure the tightness of each gas, how to design and apply the sealing gasket is of great significance.…”

The reliability of the sealing system of a proton exchange membrane fuel cell (PEMFC) is a prerequisite for ensuring the efficient and safe operation of the cell stack. In consideration of the actual assembly process, a local model of single‐cell sealing structure is constructed using a rounded corner rectangular sealing gasket structure. Apart from that, the effects of fluid pressure, bipolar plate offset, sealing gasket size, steady‐state temperature field, and seal structure on the sealing performance of PEMFC are investigated. As shown by results, with the increase of fluid pressure and sealing gasket width, the contact pressure is increased and the sealing performance is also improved. However, the increase of sealing gasket height is unfavorable to the stability and sealing performance of the stack. Meanwhile, excessive offset error leads to a sharp decrease in contact length and contact pressure at the sealing interface, which reduces the stability of the stack. With the increase of the operating temperature, the thermal expansion of the gasket increases and the contact performance improves significantly. Seals with rectangular structure have some advantages in terms of contact stability and standard deviation of contact pressure.

“…Because of its high efficiency, fast start-up, low operating temperature, and environmental friendliness, polymer electrolyte fuel cells (PEFCs) have been more and more employed in portable, stationary, and transport units to replace traditional power sources. [1][2][3][4] According to the E4tech Fuel Cell Industry Review, 5 the fuel cell (FC) sector showed a remarkable increase in supply chain of more than a gigawatt of shipments with PEFCs dominating the shipments both in number and capacity. Although the PEFCs have achieved a big progress regarding its development, the reliability issue still remains a major challenge that hinders its commercialization.…”

Efficient and robust control strategies can greatly contribute to the reliability of fuel cell systems, and a stable output voltage is a key criterion for evaluating a fuel cell system's reliability as a power source. In this study, a polymer electrolyte fuel cell (PEFC) system model is developed, and its performances under different operating conditions are studied. Then two different novel controllers-a proportional integral derivative (PID) controller and a model predictive control (MPC) controller-are proposed and applied in the PEFC system to control its output voltage at a desired value by regulating the hydrogen and air flow rates at the same time, which features a multi-input and single-output control problem. Simulation results demonstrate that the developed PEFC system model is qualified to capture the system's behavior. And both the developed PID and MPC controllers are effective at controlling the PEFC system's output voltage.While the MPC controller presents superior performance with faster response and smaller overshoot. The proposed MPC controller can be easily employed in various control applications for fuel cell systems.
