QENS Investigation of Proton Conduction Mechanism in Spark-Plasma-Sintered Protonic Ceramics Based on Doped Barium Zirconate

Abstract: Fuel cells exhibit high-energy efficiency and the only release is clean water when used with hydrogen. Proton ceramic fuel cells (PCFC) are from special interest because proton conductivity occurs already at relatively low temperatures (400°C) with positive effects on the operating time of the fuel cell. Cerium and yttrium doped barium zirconate (BZCY) has emerged as a leading candidate material for fabrication of dense proton conducting ceramics which can be used as electrolyte materials. BCZY exhibits the two required properties for a PCFC electrolyte: a satisfying protonic conductivity and a sufficient stability.We propose to carry out QENS on BZCY fabricated by Spark Plasma Sintering (SPS) to get a better understand of the proton diffusion inside the bulk. A good insight of the proton hopping mechanisms leads to optimization of the fabrication and eventually the conductivity.
