Solid oxide electrolyser cells (SOECs) have great potential for efficient and economical production of hydrogen fuel. Element diffusion between the Ni-cermet electrode and the metal substrate of metal supported cells (MSC) is a known problem in fuel cell and electrolysis technology. In order to hinder this unintentional mass transport, different ceramic diffusion barrier layers (DBLs) are...

Synthesis of carbon nanotubes on La0.6Sr0.4CoO₃ as substrate

Thiele, Doreen ; Colmenarejo, E. Lopez-Camacho ; Grobéty, Bernard ; Züttel, Andreas

In: Diamond and Related Materials, 2009, vol. 18, no. 1, p. 34-38

A carbon nanotube/perovskite composite material was developed as material for air electrodes in fuel cells or zinc-air batteries. For this purpose, carbon nanotubes were directly grown on the perovskite La0.6Sr0.4CoO₃ impregnated with Fe solution which acted as substrate. The synthesis was carried out in a fluidised bed reactor. The carbon source was acetylene. The...
