rechargeable oxygen-zinc element with cathode on the basis of some metal-porphyrines

Abstract

The behaviour of cathodes on the basis of a tetramethoxyphenylporphyrin complex with Co(II) and 10,15,20-triphenyl-1-oxonaphto-[2, 3, 4-c,d]-porphyrin complexes with Fe(III), Co(II) in conditions of rechargeable oxygen-zinc element work have been studied. The test results for the element in potentiodynamik and galvanostatical load conditions in an alkaline solution are given. The cathodes on the basis of given electrocatalysts have shown high activity and chemical stability during tests at high density of charging and discharging current.
