CO2 electrolysis of tubular type solid oxide cells using LaGaO3 electrolyte thin film prepared by dip-coating method

Research output: Contribution to journalArticle

Abstract

Micro-tubular type solid oxide electrolysis cell was prepared by using Ni-YSZ anode support tube and La0.9Sr0.1Ga0.8Mg0.2O3−δ (LSGM) electrolyte film which was prepared by dip coating and co-sintering method. Application of the prepared tubular type solid oxide cells for CO2 electrolysis was studied. It was found that CO2 to CO was occurred selectively on tubular type solid oxide cells using LSGM thin film prepared by dip-coating method. However, comparing with the electrolysis current on planer type cells using LaGaO3 based oxide electrolyte, that of tubular type cell was much smaller and this could be assigned to the low activity to CO2 electrolysis and large IR loss of Ni-YSZ porous substrate which could be explained by re-oxidation of Ni.
