The influence of three different transition metals (Me = Fe, Co, Cu) on the oxygen reduction reaction (ORR) kinetics in acidic medium Me–N–C catalysts synthesized using Me(II)-phthalocyanine as precursors is investigated this work. Through a detailed electrochemical characterization cyclic voltammetry and rotating ring-disk electrode, several kinetic parameters such Tafel slope, order for proton, apparent activation energy, selectivity toward hydrogen peroxide production, adsorbed were...
Platinum group metal (PGM)-free catalysts for oxygen reduction reaction (ORR) have attracted increasing interest as potential candidates to replace Pt, in the view of a future widespread commercialization polymer electrolyte fuel cell (PEFC) devices, especially automotive applications. Among different types PGM-free catalysts, M–N–C materials appear be most promising ones terms activity. These can produced using wide variety precursors containing C, N, and one (or more) active transition...
Abstract The atomic dispersion of nickel in Ni‐N‐C catalysts is key for the selective generation carbon monoxide through electrochemical dioxide reduction reaction (CO 2 RR). Herein, study reports a highly selective, atomically dispersed Ni 1.0% ‐N‐C catalyst with reduced loading compared to previous reports. Extensive materials characterization fails detect crystalline phases, reveals highest concentration metal, and confirms presence proposed Ni‐N x active site at this loading. shows...
Anion exchange membrane water electrolysis (AEMWE) is a promising technology to produce hydrogen from low-cost, renewable power sources. Recently, the efficiency and durability of AEMWE have improved significantly due advances in anion polymers catalysts. To achieve performances lifetimes competitive with proton or liquid alkaline electrolyzers, however, improvements integration materials into electrode assembly (MEA) are needed. In particular, oxygen evolution reaction (OER) catalyst,...
Abstract Alkaline membrane fuel cells (AMFCs) have started to become more attractive in recent years due the development of polymeric membranes with good anionic conductivity and durability. However, few studies investigating performance H 2 /O fueled AMFCs alkaline direct ethanol (DEFCs) electrode assemblies (MEAs) fabricated Pt‐group metal (PGM)‐free catalysts are available literature. In this paper, we synthesized fully characterized a Fe−Co−N−C electrocatalyst for oxygen reduction...
The ionomer content in platinum group metal (PGM)-free polymer electrolyte fuel cell (PEFC) cathode catalyst layer (CCL) plays an important role the electrode gas transport properties, proton conductivity, and hence, membrane assembly (MEA) performance. In this work, CCL is varied, influencing microstructure by altering porosity, tortuosity, as well distribution coverage of particles. A novel technique consisting a H 2 pump, combined with Pt black sensor layer, used to measure bulk mass...
