The Fuel Electrode Material Using Fe-YSZ Cermet

Electrodeposition of Cu into a Highly Porous Ni/YSZ Cermet

The electrochemical deposition of Cu into 0.12 cm and 60 μm thick, highly porous 65 vol % Ni/yttriastabilized zirconia (YSZ) cermets was investigated. An electrochemical cell in which the electrolyte solution was allowed to flow through a porous Ni/YSZ substrate was used to eliminate mass-transfer limitations and to determine the conditions for which the potential drop in the electrolyte soluti...

Novel Nanotube Buckypaper as Electrode Material for Fuel Cell Applications

We present novel supported electro-catalytic systems based on metallic/bimetallic (Pt, Au-Pt) nanoparticles decorated carbon nanotubes Buckypaper (BP), and Bilirubin Oxidase (BOD) decorated Buckypaper-based biocathodes in neutral medium for direct glucose fuel cell. The electrodes have been tested for their suitability in mixed-reactant biofuel cell applications in a phosphate buffer solution (...

Preparation of Ni-ysz Nano-fiber Composite as Fuel Cell Anode Material

A novel route to fabricate nano-fiber anode material for solid oxide fuel cells (SOFCs) is presented. Firstly, uniform nano-fibers of 8 mol % Yttria Stabilized Zirconia (8YSZ) were formed in an electrospinning process; then, these electrospun fibers were calcined at temperatures up to 1300 °C; and finally the ceramic 8YSZ nano-fibers were coated with nickel in an electroless plating process. Th...

Properties of Ni/ysz Cermets Depending on Their Microstructure

A cermet (ceramic metal composite) of Nickel and Yttria stabilized Zirconia (YSZ) is the most commonly used fuel electrode for Solid Oxide Fuel Cells (SOFC). The properties of such cermets depend strongly on their microstructure. Several Ni/YSZ cermet samples with different Ni content and Ni and 8YSZ grain size have been prepared. The thermal expansion coefficient (TEC) of these samples was mea...
