Special Issue Information

Dear Colleagues,

Solid oxide fuel cells (SOFCs) are all-solid state devices converting the chemical energy of gaseous fuels, such as hydrogen or natural gas, into electricity, via electrochemical processes and presenting advantages such as high energy conversion efficiency, low greenhouse gas emission, or flexibility of fuels. SOFCs consist in elementary units of two porous components (anode and cathode) separated by a highly dense component (electrolyte), assembled in stacks by interconnects. Although many materials for SOFCs have been developed over past years, challenges of cost and limited durability remain, which are linked to surface properties such as bad interface between the different materials or between materials and gaseous atmosphere, but also to bulk properties of the materials, such as ion diffusivity, electronic conduction and electrocatalytic activity, which are governed at the nano-scale level.

The purpose of the present issue is to collect state-of-the art work resulting in an increase electrode materials properties (ionic and electronic conductivity, electro-catalysis, chemically compatibility towards gases, thermal stability or porosity, etc.) or electrolyte and interconnects properties (ionic conductivity, chemical and mechanical compatibility with the other components of the cell, sintering ability, etc.). Review articles or research papers dealing with improvements of these compounds at the nano-structured levels are solicited and welcomed.

In this work, a mechanochemical route was proposed for the synthesis of the PrBaMn2O5+δ (PMBO) double layered perovskite phase. The mechanochemical reaction between Pr6O11, BaO2, and MnO powders with cationic stoichiometric ratios of 1/1/2 for Pr/Ba/Mn was performed using high-energy milling conditions in air. After 150 min of milling, a new phase with perovskite structure and cubic symmetry consistent with the A-site disordered Pr0.5Ba0.5MnO3 phase was formed. When this new phase was subsequently annealed at a high temperature in an inert Ar atmosphere, the layered PrBaMn2O5+δ phase was obtained without needing to use a reducing atmosphere. At 1100 °C, the fully reduced layered PrBaMn2O5 phase was achieved. A weight gain was observed in the 200–300 °C temperature range when this fully reduced phase was annealed in air, which was consistent with the transformation into the fully oxidized PrBaMn2O6 phase. The microstructural characterization by SEM, TEM, and HRTEM ascertained the formation of the intended PrBaMn2O5+δ phase. Electrical characterization shows very high electrical conductivity of layered PBMO in a reducing atmosphere and suitable in an oxidizing atmosphere, becoming, therefore, excellent candidates as solid oxide fuel cell (SOFC electrodes).
