Keywords: anion exchange membrane fuel cell heterogeneous homogeneous catalysis; anion exchange membrane fuel cell; cathodic catalyst layer; homogeneous catalysis; oxygen reduction reaction.They researched the compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1 ).Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:28903-71-1) here.
In anion exchange membrane fuel cells, catalytic reactions occur at a well-defined three-phase interface, wherein conventional heterogeneous catalyst layer structures exacerbate problems, such as low catalyst utilization and limited mass transfer. We developed a structural engineering strategy to immobilize a mol. catalyst tetrakis(4-methoxyphenyl)porphyrin cobalt(II) (TMPPCo) on the side chains of an ionomer (polyfluorene, PF) to obtain a composite material (PF-TMPPCo), thereby achieving a homogeneous catalysis environment inside ion-flow channels, with greatly improved mass transfer and turnover frequency as a result of 100% utilization of the catalyst mols. The unique structure of the homogeneous catalysis system comprising interconnected nanoreactors exhibits advantages of low overpotential and high fuel-cell power d. This strategy of reshaping of the catalyst layer structure may serve as a new platform for applications of many mol. catalysts in fuel cells.
