My current research focuses on the development of a platinum replacement electrode for oxygen sensors or fuel cells.  The electrode material is Lanthanum Strontium Aluminum Manganite (LSAM), a derivative of lanthanum strontium manganite (LSM), a common electrode material using in conjunction with YSZ.  LSAM is made by microwave synthesis and is joined to YSZ by a low temperature hot pressing method whereby a steady state increase in force is applied to join materials by plastic deformation.  Characteristics of the joint include low joining temperatures and a pore free junction without use of a green interlayer.  Electrical and ionic characterization of LSAM is ongoing as is its testing with YSZ as an oxygen sensor as shown below.
