Performance of Solid Oxide Fuel Cells (SOFCs) depend on many parameters including the operating temperature, geometric parameters such as Triple Phase Boundary (TPB) and thickness of the membrane, and transport and electrocatalytic behavior of the materials. Nano-scale materials have been proposed to enhance the electro-activity of membranes. In this paper we present an approach to enhance the TPB using nantubes grown directly on the surface of the membranes. By introducing nitrogen doped vertically aligned oriented carbon nanotubes (CNTs), it is proposed that not only the electrocatalytic behavior of these membranes increase, the TPB can be enhanced in a very controlled manner and increase the interaction region by orders of magnitude. The paper presents fabrication and electrical measurements of these membranes.
