Welcome

Dr. Jason D. Nicholas PhotoWelcome to the Solid State Ionics Laboratory at Michigan State University. Our mission is to develop device-enabling and cost-effective materials/processing routes for high efficiency chemical-to-electrical energy conversion / storage devices (batteries, fuel cells, chemical separators, chemical reactors, pseudo-capacitors, etc) and environmentally-aware devices (electro-chromic coatings, chemical sensors, and chemical actuators). Presently we are focused on a) mechano-chemical coupling in electro-chemically active solids, b) cost-effective processing methodologies, and c) nano-composite Solid Oxide Fuel Cell (SOFC) electrode performance modeling / micro-structural optimization. Some of our recent accomplishments include the publication of most highly cited gadolinium doped ceria sintering aid paper of the last decade (available here),1 the development of the world’s most highly cited nano-composite Solid Oxide Fuel Cell electrode model (the SIMPLE model, described here),2-4 and the development of an in situ, electrode-free bilayer curvature relaxation technique for measuring oxygen surface exchange coefficients as a function of simultaneously measured stress state (described here).5
