Description
The raw data of paper titled 'High-performance protonic ceramics fuel cell cathode using protophillic mixed ion and electron conducting material', the raw data includes the XRD, I11, TGA and electrochemical property measurement Abstract: Protonic ceramic fuel cells (PCFCs) are attractive energy conversion devices for low-temperature operation (400-600 °C), however wide application of PCFCs requires new high-performance electrode and electrolyte materials. Ba0.5Sr0.5Co0.7Fe0.3O3-d (BSCF) was considered as a promising candidate for PCFC cathode, however, the chemical instability of BSCF under operating conditions and its poor compatibility with electrolyte materials have limited its application. Based on our previous study on a self-assembled nanocomposite perovskite, Ba0.5Sr0.5(Co0.7Fe0.3)0.6875W0.3125O3-d (BSCFW), here we report the electrochemical and protonic properties of BSCFW considered as a PCFC cathode material. BSCFW shows favourable thermodynamic and kinetic protonic behaviour, and the BSCFW single cell presents an excellent non-ohmic resistance of 0.172 Ω cm2 at 600 °C. Our comprehensive characterization of the protonic properties of BSCFW provides that our previous findings on phase-separation of BSCFW enables to use BSCF as a PCFC cathode by interplay of mixed-phase through W-doping and it provides important background for the systematic development of PCFC cathodes.
