VERFAHREN ZUR HERSTELLUNG EINER KUNSTSTOFFGEBUNDENEN GASDIFFUSIONSELEKTRODE, DIE EINEN MANGANOXIDKATALYSATOR DER UEBERWIEGENDEN ZUSAMMENSETZUNG EINES GEMISCHES AUS DIMANGANTRIOXID UND PENTOMANGANOKTOXID ENTHAELT.

摘要

Prodn. of a plastics bonded, manganese oxide (Mn2O3.xMn5O8) catalyst contg. gas diffusion electrode, esp. for fuel cells, chloralkali cells and air oxygen elements, involves thermally decomposing MnCO3 in an air stream at 450-550 deg.C, intensively mixing the resulting manganese oxide catalyst powder with PTFE and one or more of carbon black, graphite and active carbon, rolling the mixt. to a foil and rolling the foil into a metal mesh.
