- Abstract
- Protonic Ceramic Fuel Cells (PCFCs) have recently gained interest due to their advantages on decreasing solid oxide fuel cell operating temperatures. Proton conducting electrolyte materials based on Y-doped BaCe1-xZrxO3 have been investigated, because of their high proton conductivity and chemical stability at 500 to 800°C.
The development of proper cathode materials for PCFCs remains a challenge, since the high polarization at the cathode side is still a hindrance to PCFC development. To this end, recent studies have highlighted the potential of layered materials based on Ruddlesden-Popper series (An+1BnO3n+1) for cathode applications. In particular n=1 members, notably those based on Ln2NiO4+???have to be underlined.
In this work, aiming to investigate the possible use of Pr2NiO4+? cathode materials with BaCe0.65Zr0.20Y0.15O3??BCZY? electrolyte, anode-supported PCFCs based on Ni-BCZY/ BCZY/Pr2NiO4+??were prepared. A colloidal spray deposition technique was developed for the preparation of BCZY dense electrolyte films on Ni-BCZY porous cermets. The cathode layer was deposited by screen-printing.
The cell has been characterized in single cell configuration in the temperature range 550-750°C. The cell, fed with wet H2 and air, exhibited a 1V open circuit voltage and a maximum power density of 40 mW/cm-2 at 600°C.
With the view of understanding the cell performance, chemical compatibility between Pr2NiO4+? and BCZY was checked at high temperatures and under operating conditions. (literal)
