A promising alternative to fossil fuel energy is the fuel cell technology. Proton exchange membrane (PEM) fuel cells are widely used in electric vehicle and mobile power generation fields. There are several components in the PEM fuel cell, namely the gas diffusion layer (GDL), PEM, catalyst layer (CL) and bipolar plate (BPP). The GDL is one of the key components of a PEM fuel cell and acts as a distributor of reagents, current conductor, water manager and a CL support. This paper presents an analysis of the materials and fabrication technologies of the GDL in the PEM fuel cell. A summary of the main materials for manufacturing the macroporous substrate (MPS) and microporous layer (MPL) of GDL was presented. Advanced manufacturing methods were described as single layer manufacturing, double layer manufacturing and multilayer manufacturing. A brief overview of the materials and manufacturing processes of BPP and CL were also presented. Future research directions have also been proposed.

Li et al [61] stacked two MPLs with the same thickness and different pore size by spraying the solutions with different content of CaCO 3 as the pore-forming agent. The as-prepared MPL exhibited a gradient distribution of pore size along the thickness direction, improving the water/vapor management capabilities of the fuel cells.…”

Gas Diffusion Layer for Proton Exchange Membrane Fuel Cells: A Review

Proton exchange membrane fuel cells (PEMFCs) are an attractive type of fuel cell that have received successful commercialization, benefitted from its unique advantages (including an all solid-state structure, a low operating temperature and low environmental impact). In general, the structure of PEMFCs can be regarded as a sequential stacking of functional layers, among which the gas diffusion layer (GDL) plays an important role in connecting bipolar plates and catalyst layers both physically and electrically, offering a route for gas diffusion and drainage and providing mechanical support to the membrane electrode assemblies. The GDL commonly contains two layers; one is a thick and rigid macroporous substrate (MPS) and the other is a thin microporous layer (MPL), both with special functions. This work provides a brief review on the GDL to explain its structure and functions, summarize recent progress and outline future perspectives.

“…The addition of the MPL to the MPS is crucial as it facilitates the humidification of the PEM, thereby enhancing the overall performance of the PEM fuel cell 24 . The preparation method of GDL can affect the transport of water and gas, and the preparation methods of spray method and squeegee method have been adopted 25 . At present, there are many problems in the process of commercialization of the GDL, such as complex process, very high temperature (2000°C), excessive thickness, and high cost 12 .…”

Because of the global energy crisis, many researchers have focused their efforts on fuel cells. The gas diffusion layer (GDL) is a fundamental component of proton exchange membrane (PEM) fuel cells. The manufacturing procedures for traditional carbon‐based GDLs are sophisticated and energy‐intensive, and have design flexibility constraints, making it difficult to build complicated forms and structures. Additive manufacturing is widely used in a variety of fields, with the fused deposition modeling (FDM) technique being the most popular method. Prior to conducting systematic research on the printed GDLs, it is necessary to investigate the pore parameters with the support of FDM technique. In this research, the initial step involves material selection, FDM printer selection, and modeling. Subsequently, printing analysis and sample characterization are conducted to select an acceptable pore shape. A water drainage test determines the appropriate pore size, followed by additional tests for acceptable porosity range. The square pore shape is determined to be more suitable. A pore side length of 1.0 mm is identified. Furthermore, a suitable pore range of 10.9%–30.3% is identified. Next step, the printed GDLs will undergo further testing to investigate their suitability to be used in PEM fuel cells.
