Corrosion Study of Cr-Oxide Ceramics Using Rotating Ring Disk Electrode

Proton Exchange Membrane Electrolysis demands new resistant and cheap materials for the anode components, and Cr-based spinels are acid stable ceramics, which may meet the requirements of such application to some extent. This work reports the electrochemical behavior of spinel-structured MnCu0.25Cr1.75O4 and NiCr2O4 up to 2.0 V in order to determine the stability/dissolution of such materials when exposed to anodic potential.

The ceramic/graphite composite was deposited on a rotating ring disk electrode and scanned while the ring electrode was held at 0.5 V vs SHE. The dissolution of Cr species was observed to happen as the oxidation proceeded by collecting the dissolved products at the ring electrode. HCrO4− and MnO4− were identified as dissolved products.

Analysis of post-test solutions, revealed the difference between chemical and electrochemical corrosion of the materials.
