“…The superior EOR performance of Pt and Pd in the PtPd alloy is attributed to their synergistic effects. Fonseca et al 98 created a modified screen‐printed electrode in a flow device to test nanoparticle electroactivity for electrooxidation by alcohol. The modification offers new knowledge related to the hydrodynamic current performance and the use of an open device that is close to the actual value.…”

Summary Fuel cells offer the possibility of zero‐emission electricity generation and increased energy security. However, fuel cell technology, particularly the low‐temperature fuel cell, still has some major problems that hinder their commercialization, including costly components, durability issues, hydration, and an efficiency loss of approximately 60% during operation. Recently, graphene has been introduced as a potential solution to enhance the performance of fuel cell systems. This article presents a review on the application of graphene in fuel cell technology and the presentation of the electrochemical characteristic of graphene. This article also summarizes the recent research trends in graphene and its economic aspects, with a discussion on the modifications that increases the graphene strength along with other benefits for the future development of graphene technology. Finally, this work also addressed the current problems and future advances in adopting graphene in a low‐temperature fuel cell system.

“…In 2017, nine new FIA-SPE methods for the determination of the following analytes were developed: isoniazid drug, [51] serotonin, [52] uric acid, [53] nitrite, [54] proton activity, [55] H 2 O 2 , [56] lactose, [57] 2-nitro-p-phenylenediamine, [58] and the electroactivity of nanoparticles. [59] During this year, two new flow cells were proposed for coupling with SPEs. The first one was a thin-layer flow-cell that combined CSPE as the electrode surface and optical instrumentation (electrogenerated chemiluminescence).…”

“…In this report, the SPE was integrated into an one-channel disposable thin-layer transparent flow-cell, offering the advantages of miniaturization, facile electrode modification and replacement. Fonseca et al [59] reported for the first time the study of electroactivity of nanoparticles using a FIA system integrated within a SPE cell. The proposed method is robust, reproducible and provides new information, due to the hydrodynamic current output and the use of an opened system, which is closer to a real fuel cell scenario.…”

This review addresses the use of screen-printed electrodes (SPEs) coupled to flow systems such as flow injection analysis (FIA), batch injection analysis (BIA), and high-performance liquid chromatography (HPLC) systems over the last six years (since 2014). The combination of SPEs and flow systems is a powerful synergy to increase the throughput of measurements, improve electrode lifetime, and reduce reagent consumption and waste generation. Recently, commercial flow cells for SPEs were made available by different companies and potential new users that are unable to construct homemade electrochemical flow cells have been attracted to work in the area. This overview aims to show both trends and future potential for the development of new methods useful for modern electroanalysis and/or portable applications.
