Catalysing carbon for electrodes - in electrochemical fuel cells for oxygen reduction

摘要

Catalyst in active form is produced and then added to C material. Prod. is used for galvanic elements, esp., O2 redn. electrodes for fuel cells. Qualitatively high grade activated C is economically produced, since only small amts. of substances need be subjected to chemical or physical treatment. Electrochemical capacity and durability can be adjusted.
