News About This Professor

Education 

Ph.D., Stanford University, 1990

Research Interests 

Solid oxide fuel cells, gas separation membranes, solid-state gas sensors, electrocatalytic conversion of CH4, post-combustion reduction of NOx.

Background 

Eric Wachsman, an expert on solid oxide fuel cells, is the University of Maryland Energy Research Center's first director.

Before joining the University of Maryland, he spearheaded the creation of the Florida Institute on Sustainable Energy at the University of Florida, and served as a senior scientist at SRI International.

Wachsman has focused his career on developing advanced, efficient, energy conversion devices and technologies. His research is on ionic transport in solids and the heterogeneous electrocatalysis at their surface. This research includes the development of solid oxide fuel cells, gas separation membranes, solid-state gas sensors, the electrocatalytic conversion of CH4, and the post-combustion reduction of NOx using advanced ion conducting materials.

Wachsman is a Fellow of the Electrochemical Society (ECS) and the past chair of the High Temperature Materials Division of ECS. He is the editor-in-chief of <em>Ionics.</em> and former associate editor of the Journal of the American Ceramic Society. He has more than 140 publications and eight patents on ionic and electronic transport in ceramics, their catalytic properties, and device performance.

Wachsman is also a frequently-invited panelist on fuel cell and hydrogen energy research, ranging from the U.S. Department of Energy "Fuel Cell Report to Congress" and "Basic Research Needs Related to High Temperature Electrochemical Devices for Hydrogen Production, Storage and Use," to the National Science Foundation "Workshop on Fundamental Research Needs in Ceramics," NATO "Mixed Ionic-Electronic Conducting (MIEC) Perovskites for Advanced Energy Systems,” and the National Academies' “Global Dialogues on Emerging Science and Technologies."

Current Research Projects 

The Wachsman lab is at the forefront of renewable energy research involving high temperature ceramics. Dr. Wachsman's advances in fundamental ionic transport and electrocatalysis have revolutionized solid oxide fuel cells (SOFCs), ion transport membranes, and solid state sensors. SOFCs convert fuels directly into electricity, water and CO2, offering exciting applications in utility scale and automobile energy storage. Ion transport membranes are key to syn gas production systems. Solid state sensors provide an inexpensive, rugged sensor that offers a high temperature tolerance and long life span in applications such as NOx detection in combustion exhaust.

These technologies are on the verge of commercialization and changing the landscape of energy. The deployment and continued development of these devices will increase the flexibility of how and when energy is used and decrease the price.
