“…383 There has only been sparse work devoted to the cathode (oxygen reducing) side of the polymer fuel cell membrane. 384 One study was devoted to screening the Pt-Ni-Zr ternary system for oxygen reduction reaction properties. 385 In a related work, 5 Pt group metals (Pt, Ru, Os, Ir, and Rh) systems were screened for their bifunctional oxygen reduction and water oxidation properties; it was demonstrated that replacing most of the Ir in PtIr alloys with Ru improved catalyst activity.…”

High throughput (combinatorial) materials science methodology is a relatively new research paradigm that offers the promise of rapid and efficient materials screening, optimization, and discovery. The paradigm started in the pharmaceutical industry but was rapidly adopted to accelerate materials research in a wide variety of areas. High throughput experiments are characterized by synthesis of a "library" sample that contains the materials variation of interest (typically composition), and rapid and localized measurement schemes that result in massive data sets. Because the data are collected at the same time on the same "library" sample, they can be highly uniform with respect to fixed processing parameters. This article critically reviews the literature pertaining to applications of combinatorial materials science for electronic, magnetic, optical, and energy-related materials. It is expected that high throughput methodologies will facilitate commercialization of novel materials for these critically important applications. Despite the overwhelming evidence presented in this paper that high throughput studies can effectively inform commercial practice, in our perception, it remains an underutilized research and development tool. Part of this perception may be due to the inaccessibility of proprietary industrial research and development practices, but clearly the initial cost and availability of high throughput laboratory equipment plays a role. Combinatorial materials science has traditionally been focused on materials discovery, screening, and optimization to combat the extremely high cost and long development times for new materials and their introduction into commerce. Going forward, combinatorial materials science will also be driven by other needs such as materials substitution and experimental verification of materials properties predicted by modeling and simulation, which have recently received much attention with the advent of the Materials Genome Initiative. Thus, the challenge for combinatorial methodology will be the effective coupling of synthesis, characterization and theory, and the ability to rapidly manage large amounts of data in a variety of formats.

“…Proton exchange membrane fuel cells (PEMFCs) are well known as a new and clean energy source due to their high energy density, high energy‐conversion efficiency and low operation temperature. However, to fully achieve these advantages, the sluggish oxygen reduction reaction (ORR) at the cathode has to be catalyzed by Pt and/or Pt‐based catalysts which are of high cost and low reserve in nature . Meanwhile, with the commercialization of more and more fuel cells and the increase of market demand, the price of the precious metal of Pt will rapidly increase further.…”

Developing Pt-free catalysts with high activity and durability is considered as an essential step for cost reduction and real commercialization of fuel cells. Previous Pt-free catalysts are either lack of activity and/or insufficient in durability. Here we report the first synthesis of a carbon-supported PdFe catalyst with a fully ordered intermetallic structure by controlling the atomic ratio of Pd and Fe and high-temperature annealing for structural ordering. This intermetallic catalyst is then doped with a trace amount of Au (atomic ratio of Au/Pd: 1/50) mainly in the surface region of the ordered lattice. Such an Au-doped intermetallic PdFe catalyst is finally demonstrated to possess a comparable catalytic activity and much better durability for oxygen reduction reaction than the commercial catalyst of Pt/ C. For example, the half-wave potential of the Au-PdFe catalyst decreases at a rate 9 times slower than that of Pt/C catalyst after potential cycling under harsh electrochemical conditions. The excellent activity and durability of this new catalyst is attributed to the ordered structure of PdFe particles and the protective effect of the surface Au doping. This study provides a new strategy to developing Pt-free catalysts, lowering the production cost, and accelerating the practical application of fuel cells.

“…Multicopper oxidases, especially laccase (Lac) and bilirubin oxidase, have been widely studied as fuel cell catalysts for oxygen reduction in enzymatic bio-cathodes, whereby oxygen is fully directly reduced to water with zero H 2 O 2 emission [1][2][3][4][5][6][7][8][9][10][11][12][13]. The multi-copper oxidases have four copper atoms in their active sites, classified into type-1 (T1), type-2 (T2) and type-3 (T3) Cu sites.…”

“…The mechanism of multi-copper oxidase function includes three major steps: the T1 Cu site is reduced by electron transfer from a reduced substrate, then intramolecular electron transfer occurs between the T1 Cu site and T3 Cu over a distance of ca. 1.3 nm, and then O 2 is reduced to two H 2 O molecules at the trinuclear copper site T2/3 Cu [1][2][3][4][5][6][7][8][9][10][11][12][13]. Multicopper oxidases have been studied extensively as a bio-cathode electrocatalyst by exploiting direct and mediated electron transfer reactions [4,11,12].…”
