“…Several papers report such experimental findings during co-electrodeposition of Ni and Cu. [24][25][26] When the Cu content is higher than almost 50%, there can be segregation of the individual atoms rather than the formation of a homogeneous alloy. [25] It is worth noting the effect of Mo presence on the crystallinity degree of Ni.…”

Several functionalized porous transport layers with Pt‐free electrocatalysts for hydrogen evolution reaction in alkaline conditions, based on Ni, Cu, and Mo, are prepared through electrodeposition onto a 304 stainless steel mesh. Morphological characterization confirms the fabrication of electrodes with high electrochemical surface active area due to the formation of hierarchical nanostructures. Mo presence into the electrocatalysts increases the activity toward the hydrogen evolution reaction. The optimization of electrodeposition process leads to the preparation of highly active NiCuMo electrocatalyst that exhibits near zero onset overpotential and overpotentials of 15 and 113 mV at 10 and 100 mA cm−2, respectively, in 1 m KOH electrolyte. Moreover, this electrocatalyst shows superior stability with respect to other Pt‐free electrocatalysts, reaching 100 h of durability with low overpotentials value demonstrating the successful preparation of very promising functionalized porous transport layers for future‐generation alkaline electrolyzers.

Additive manufacturing (AM) technologies have many advantages, such as design flexibility, minimal waste, manufacturing of very complex structures, cheaper production, and rapid prototyping. This technology is widely used in many fields, including health, energy, art, design, aircraft, and automotive sectors. In the manufacturing process of 3D printed products, it is possible to produce different objects with distinctive filament and powder materials using various production technologies. AM covers several 3D printing techniques such as fused deposition modeling (FDM), inkjet printing, selective laser melting (SLM), and stereolithography (SLA). The present review provides an extensive overview of the recent progress in 3D printing methods for electrochemical fields. A detailed review of polymeric and metallic 3D printing materials and their corresponding printing methods for electrodes is also presented. Finally, this paper comprehensively discusses the main benefits and the drawbacks of electrode production from AM methods for energy conversion systems.

“…The use of PLA in 3D‐electrode production is advantageous because it is a low‐cost, easy method and non‐toxic products 37,38 . In addition, 3D‐printed electrodes that provide high mass transfer in any geometry can be designed 2 . For example, Foster et al 39 have used for the first time a 3D‐printed electrode fabricated from graphene‐based PLA filament as the electrocatalyst in the energy storage architectures.…”

In this study, polylactic acid (PLA) composites containing different ratios (5%–15%) of graphene (GRP) and carbon nanofiber (CNF) were filamented using an extruder and then, 3D printed electrodes were produced by fused deposition modeling (FDM) method using the obtained GRP‐PLA and CNF‐PLA based filaments. The Electrochemical measurements of the 3D electrodes toward the hydrogen evolution reaction (HER) were investigated. According to the results obtained from the cathodic curves; It was determined that the current densities of 15% GRP/PLA and 15% CNF/PLA 3D electrodes were higher than the other electrodes and these values were around 0.325 and 0.329 mA cm−2, respectively. From the EIS results, the resistance values (Rct + Rad) for 15% GRP/PLA and 15% CNF/PLA 3D electrodes were found to be around 1465 and 9135 Ω cm2, respectively. It was determined that these two 3D electrodes had the lowest resistance values compared to other ratios. To increase the efficiency for HER, after soaking in 1 M KOH for 1 h, the activation process was carried out using the CV method by taking 100 cycles in the 0/−3 V range. The results were compared with the activation method reported in the literature (DMF and 2.5 V electrochemical treatment).
