TL;DR: Electrocoagulation showed that with increasing applied potential and electrolysis time, the Al(3+) dosage increases, and thereby favouring the fluoride ions removal, and it was observed that defluoridation is dependant on the concentration of supporting electrolyte.

TL;DR: In this article, the inner and outer differential capacities of oxide coatings were derived from the linear dependencies of the voltammetric capacitive current, ic, with the potential sweep rates, ν, observed in the low and high domains.

TL;DR: In this paper, the authors report processing and geometric design criteria for the fabrication of free-standing electrolyte membranes for micro-scale solid-oxide fuel cells for portable power generation in the form of micro-micron, dense, nanocrystalline yttria-stabilized zirconia (YSZ) and gadolinium-doped ceria (GDC) films.
Abstract: Micromachined fuel cells are among a class of microscale devices being explored for portable power generation In this paper, we report processing and geometric design criteria for the fabrication of free-standing electrolyte membranes for microscale solid-oxide fuel cells Submicron, dense, nanocrystalline yttria-stabilized zirconia (YSZ) and gadolinium-doped ceria (GDC) films were deposited onto silicon nitride membranes using electron-beam evaporation and sputter deposition Selective silicon nitride removal leads to free-standing, square, electrolyte membranes with side dimensions as large as 1025 μm for YSZ and 525 μm for GDC, with high processing yields for YSZ Residual stresses are tensile (+85 to +235 MPa) and compressive (–865 to -155 MPa) in as-deposited evaporated and sputtered films, respectively Tensile evaporated films faul via brittle fracture during annealing at temperatures below 773 K; thermal limitations are dependent on the film thickness to membrane size aspect ratio Sputtered films with compressive residual stresses show superior mechanical and thermal stability than evaporated films Sputtered 1025-μm membranes survive annealing at 773 K, which leads to the generation of tensile stresses and brittle fracture at elevated temperatures (923 K)
