Introduction

Solid oxide electrolysers (SOEs) and fuel cells (SOFCs) are advantages, as a large proportion of the required energy can be supplied as heat energy. Furthermore, higher temperatures enhance kinetics and solid oxide systems allow for the highest reactant flexibility and stability.

This project aims is focusing on tubular Ni-YSZ|YSZ|YSZ-LSM|LSM electrochemical reactors for the reduction of CO2 and/ or H2O to H2. These tubular reactors were produced by co-extrusion phase-inversion of the inner electrode and electrolyte (NiO-YSZ|YSZ) in collaboration with Professor Kang Li’s Research Group. Tubular reactors are beneficial due to improved mechanical and thermal stability, as well as easier sealing.
