This study presents a novel current collector design for a tubular SOFC and numerically investigates its performance. The new current collector design has a flow channel with a trapezoidal shape. Several channels, such as four, eight, and twelve, are investigated, and their effects on cell performance are reported and compared. Additionally, a traditional tubular SOFC and the newly developed design are presented. The equations of mass conservation, momentum, charge transport, and energy were considered in the numerical model, and the ANSYS Fluent SOFC module was used to solve the numerical model. The results show that the developed design performed better than the traditional design. The new design with twelve channels collected 0.384 A, higher than the other designs. Although the design with twelve channels gave a high concentration of hydrogen at the outlet compared to the designs with four and eight channels, it gave higher performance than the designs with four and eight channels. Increasing the number of channels in the developed design enhanced the cell performance significantly due to the increased contact area, leading to the efficient collection of the generated current.

“…However, improvements in the technical and economical aspects of the fuel cell are still required for commercialization. Research has been focusing on the optimization of the fuel cell by optimizing the configuration, materials, conformation, and structure of the catalyst layer [5][6][7][8][9]. For instance, several research studies have focused on decreasing the cost of PEMFCs by enhancing the electrolyte conductivity [10][11][12][13].…”

A Critical Review on the Use of Ionic Liquids in Proton Exchange Membrane Fuel Cells

et al. 2022

View full text Add to dashboard Cite

This work provides a comprehensive review on the incorporation of ionic liquid (ILs) into polymer blends and their utilization as proton exchanges membranes (PEM). Various conventional polymers that incorporate ILs are discussed, such as Nafion, poly (vinylidene fluoride), polybenzimidazole, sulfonated poly (ether ether ketone), and sulfonated polyimide. The methods of synthesis of IL/polymer composite membranes are summarized and the role of ionic liquids as electrolytes and structure directing agents in PEM fuel cells (PEMFCs) is presented. In addition, the obstacles that are reported to impede the development of commercial polymerized IL membranes are highlighted in this work. The paper concludes that the presence of certain ILs can increase the conductivity of the PEM, and consequently, enhance the performance of PEMFCs. Nevertheless, the leakage of ILs from composite membranes as well as the limited long-term thermal and mechanical stability are considered as the main challenges that limit the employment of IL/polymer composite membranes in PEMFCs, especially for high-temperature applications.

“…There are lots of studies related to the material and flow field design of HT-PEMFCs. The performance of fuel cells with different bipolar plate materials (aluminum, copper, and stainless steel) was studied numerically and experimentally by Wilberforce et al [8]. It was reported that the fuel cell with the aluminum bipolar plate provides the best performance among the three different materials.…”

In this work, a three-dimensional mathematical model including the fluid flow, heat transfer, mass transfer, and charge transfer incorporating electrochemical reactions was developed and applied to investigate the transport phenomena and performance in high-temperature proton exchange membrane fuel cells (HT-PEMFCs) with a membrane phosphoric acid doping level of 5, 7, 9, 11. The cell performance is evaluated and compared in terms of the polarization curve. The distributions of temperature, oxygen mass fraction, water mass fraction, proton conductivity, and local current density of four cases are given and compared in detail. Results show that the overall performance and local transport characteristics are significantly affected by the membrane phosphoric acid doping level.
