“…In reasonable agreement, here we report maximum power densities of ∼514.6 and 417.9 mW cm −2 for the etched and pristine assemblies, respectively as indicated in Figure b, which also translates to ∼1.2X increase in performance. While the performance of these cells does not equal contemporary state of the art MEAs , it is well known that a large range of performance can be obtained from variations in catalyst/MEA preparations . A list of conventional and restructured MEA performances from literature are provided in Table .…”

This paper presents performance results for the use of plasma‐etched Nafion membranes to suppress polarization losses in proton exchange membrane fuel cells (PEMFCs) configured from 0.1 mg cm−2 conventional Pt/C dispersion and 0.02 mg cm−2 ultra‐thin sputter‐deposited Pt catalyst layers. Four MEA configurations, namely, etched membrane‐conventional electrode, pristine membrane‐conventional electrode, etched membrane‐sputter electrode, and pristine membrane‐sputter electrode cells were explored, and their respective maximum power densities were ∼514.6, 417.9, 170.1 and 138.3 mW cm−2. The results demonstrated that independent of MEA fabrication approach, cells with O2 plasma treated membranes had reduced ohmic resistances and delivered superior performance over their pristine counterparts, validating the utility of membrane etching for achieving improved PEMFC performance.

“…The significantly high performance by sample P3 can be attributed to the achievement of overall balanced properties with high connected porosity and uniform porous network. 43,63,64 For better understanding of the above results, the polarization curve of the fuel cell can be divided into three regions, depending upon the nature of voltage losses that occur during the cell operation, and is described by eq 1. 6,52 η η η = − − − E E eq act ohmic diff (1) where E refers to the cell potential obtained at the time of fuel cell operation, E eq is the equilibrium voltage, and η act is the activation overpotential, 29 which mainly arises due to slow kinetics and is in general explained in detail by Tafel plots.…”

Configuring the Porosity and Microstructure of Carbon Paper Electrode Using Pore Formers and Its Influence on the Performance of PEMFC

et al. 2020

Carbon papers (CPs) are used as an electrode backing in PEMFC. It assists the diffusion of both the reactant gases and products toward and from the reaction site and aids the flow of electrons. CP is a carbon/carbon composite made by patterning of carbon fibers in the form of highly porous sheets called preforms, followed by composite formation. Different pore formers have been incorporated into the CP, and their effect on porosity, permeability, structure, and electrical conductivity have been analyzed and found to be significant. The unit PEMFC shows a peak output power density of 797.2 and 756.8 mW/cm 2 with camphor and urea as pore formers, compared to 576.2 mW/cm 2 obtained using the paper prepared without pore former. The effect of pore formers on the separate sections of the polarization curves has been discussed. Further, samples with urea and camphor show comparable performance with the commercial SGL paper.

“…MPL with the content of carbon powder 3 mg cm -2 made by spraying method leads to an average thickness of GDL increased 302.5 µm as shown in Figure 2. GDL thickness above 300 µm proved to have a better impact on the performance of the MEA with a thickness below it [9]. MEA performance as a result of the influence of the thickness of the electrodes has already gained the attention of researchers.…”

Carbon powder content of 1.5 mg cm -2 was referred to previous studies [7,8], while the content of 3 mg cm -2 was chosen based on other reference [9] using the vapor grown carbon fiber casting methods and using carbon cloth [10]. In this section, the manufacture of MP was conducted using casting methods with PTFE and ABC content that adapts to the content of carbon powder.…”

Carbon powder in the gas diffusion layer (GDL) contained in the membrane electrode assembly (MEA) has an important role in the flow of electrons and reactant gas. Meanwhile, the method of making the electrode is one of the many studies conducted to determine the most appropriate method to use. Comparative study of the performance of proton exchange membrane fuel cell (PEMFC) electrodes with different carbon powder content (vulcan XC-72) in the GDL and methods of manufacture of the electrode between casting and spraying method has been carried out. The spraying method consists of one layer and three layer of catalyst layer (CL). The content of carbon powder in the GDL as much as 3 mg cm -2 has a better performance compared to 1.5 mg cm -2 with an increase of 177.78% current density at 0.6 V. Meanwhile, the manufacture of CL with three-layer spraying method has better performance compared with one-layer spraying and casting method. Abstrak (Indonesian) Article InfoSerbuk karbon pada lapisan difusi gas (LDG) yang menyusun elektroda membran memiliki peran penting dalam mengatur aliran elektron dan gas reaktan. Pada sisi lain metoda pembuatan elektroda adalah salah satu dari banyak studi yang dilakukan untuk menentukan metoda yang paling sesuai yang dapat dikerjakan. Telah dikerjakan studi komparatif kinerja membran penukar proton pada elektroda sel bahan bakar dengan kandungan serbuk karbon (vulcan XC-72) dalam LDG yang bervariasi dan studi komparasi metoda pembuatan elektroda secara tuang dan semprot. Metoda semprot dikerjakan dalam dua variasi yakni pembuatan lapisan katalis (LK) satu dan tiga lapisan. Kandungan serbuk karbon dalam LDG hingga 3 mg cm -2 memiliki kinerja lebih baik dibanding 1,5 mg cm -2 dengan peningkatan kerapatan arus 17,78% pada 0,6 V. Pembuatan LK dengan metoda semprot tiga lapisan memperlihatkan kinerja terbaik dibanding metoda semprot satu lapisan dan metoda tuang.
