Optimization of proton exchange membrane fuel cell’s end plates

Abstract

In this study, we present the optimization of end plates to produce uniform pressure and low content on the gas diffusion layer in polymer membrane fuel cell. For this purpose the end plates and the influence of parameters on the gas diffusion layer pressure has been investigated. Parameters studied are the thickness of the end plate, the depth of the bipolar plates groove and the clamping pressure applied to the end plates. After defining their values in the Abaqus finite element software, mechanical analysis has been carried out to examine the stress distribution on the gas diffusion layer and the results have been extracted. By extracting the results of the analysis and importing into the Adaptive Network-based Fuzzy Inference Systems in MATLAB software, a numerical relationship between the influential values and the outputs is extracted. By investigating these relationships and defining the objective function, we investigate the algorithm required for the equation and uniformity of stress distribution on the gas diffusion layer. In this research, the bee algorithm has been used and it has been evaluating the effective parameters of the optimum fuel cell state. After final review of the results, the suggested optimum state of the bee algorithm is the thickness of the end plate 12 mm, the depth of the bipolar plate groove is 0.1077 mm and the clamping pressure is 11.0199 MPa.

Two Generations of Hydrogen Powertrain—An Analysis of the Operational Indicators in Real Driving Conditions (RDC)

“…An analysis determining the knowledge base performed for the Polish Hy Strategy has provided the research results shown below. The research process w ried out in April and May 2021 and consisted of steps including extensive cons with stakeholders in expert panels (about 100 experts-including both domestic eign), in-depth interviews (16) and a survey on a sample of 30 specialists. The stud scope, covered all of the elements of the hydrogen economy value chain-pro storage, transport, distribution and use of hydrogen.…”

“…The first generation of this drive reached a value of about 3 kW/dm 3 (MY2014), while the second generation was at 4.4 kW/dm 3 (MY2020; these values include end plates-the values may be higher otherwise). End plates play a critical role in the overall process of fuel cell optimization, as evidenced, for example, by the work of Habibnia et al [16]. Current density in subsequent generations of Toyota Mirai propulsion was increased by 15% [17].…”

Investigating the Effect of the Compensation Flow Fields on the Performance and Thermal Stress Distribution of a Typical Fuel Cell

“…18 Both the structure and operating conditions will greatly affect the fuel cell performance. 19,20 Establishing a cross-scale model and exploring the impact of a new structure design scheme on the internal performance of the fuel cell holds significant importance. 21 Therefore, a compensation flow field based on the serpentine structure is proposed.…”

Structural modeling and analysis of fuel cell: a graph-theoretic approach

“…Operation of a PEM fuel cell involves charge and ions transport, heat transfer, electrochemical reactions, and multi-phase flow. These phenomena occur in different components such as bipolar plates (BPs) ( Habibnia, Shirkhani & Tamami, 2020 ; Smitha, Sridhar & Khan, 2005 ), gas flow channels (GFCs) ( Djilali, 2007 ), and membrane electrode assembly (MEA) ( Wang, Basu & Wang, 2008 ). MEA consists of the catalyst layers (CLs), membrane and gas diffusion layer (GDL), and micro-porous layer (MPL).…”
