“…For efficient use in DFAFCs, apart from high activity toward ORR, the cathode catalysts need to be FA tolerant because the crossover of fuel from the anode to the cathode side may create a mixed potential at the cathode, resulting in low efficiency. Pt supported on composite substrates such as TiO 2 /C (Timperman et al, 2011), oleylamine‐functionalized Pd (Y. Shi et al, 2014), and CN x nanofibers (Jindal et al, 2017) were reported to be tolerant towards FA. Furthermore, catalysts such as Ir and its alloys (K. Lee et al, 2011), CoSe/C (Nekooi et al, 2010), RuSe (Timperman et al, 2011), Ru x Se y /C (Gago et al, 2011) as well as Co and Fe deposited on nitrogen‐doped carbon nanotubes (CNTs) (Abd Lah Halim et al, 2019) were reported to show high selectivity to ORR and good FA tolerance.…”

Direct formic acid fuel cells (DFAFCs) are potential candidates as power sources for various applications, especially in portable electronics and medical diagnostic devices. Though they have been the subject of considerable research, commercial prototypes of DFAFCs are rudimentary compared to other liquid fuel cells, particularly the widespread methanol‐based direct methanol fuel cells. Various strategies for rationally engineering the electrocatalysts for enhancing DFAFC performance have been explored in the last few years, such as alloying noble metals with earth‐abundant transition metals, designing specific morphological and structural arrangements, decorating the surface with corrosion‐tolerant cocatalysts, and providing better catalyst support for effective catalyst dispersion. An overall approach may be necessary and should include (i) understanding the underlying mechanism, which will guide the direction of catalyst engineering, (ii) employing morphological, compositional, and structural control of the electrocatalysts to improve catalyst utilization and enhance the intrinsic activity for real‐world applications, and (iii) integrating these in a proficiently designed cell architecture suitable for targeted applications. In this review, we focus on the recent advances in electrocatalysts, formic acid electrooxidation mechanisms, and DFAFC cell architectures, which could help address the opportunities and challenges of commercializing DFAFC as a prospective alternative power source for portable applications.

“…Characteristics of electrospinning include high tunability over the fiber dimension and morphology, high versatility over the type of polymer that can be electrospun, and possible functionalization of the fibers [3][4][5][6][7][8]. This makes it a technique of choice for a wide range of applications, for example tissue engineering, drug delivery, filtration, catalyst support, sensors and energy devices [9][10][11][12][13][14][15][16][17][18].…”

This paper reports on the rapid fabrication of radially-aligned, three-dimensional conical structures by electrospinning. Three different polymers, Polyvinylpyrrolidone, Polystyrene and Polyacrylonitrile were used to electrospin the cones. These cone structures are spreading out from a vertical conductive pillar, which can be arbitrarily placed on specific part of the collector. The lower part of the cone is clearly defined on the collector, and the cone has a relatively uniform radius around the pillar. The cones are constituted of fibers that are radially aligned towards the top of the pillar, but there is no apex and the fibers fall flat on the top of the pillar surface. A parametric study has been performed to investigate the effects of the pillar morphology (height and thickness) and the electrospinning parameters (applied voltage and working distance) on the overall shape and size of the cone structure, as well as the fiber alignment. The pillar morphology influences directly the cone diameter and height. The electrospinning parameters have little effect on the cone structure. The formation mechanism has been identified to be related to the shape of the electric field, which has been systematically simulated to understand the effect of the electric field lines on the final dimensions of the cone structure.
