Biography

Jeff Stevenson has over 30 years of experience in the materials science field. Since joining PNNL in 1993, his work has focused primarily on the development and characterization of electrical ceramic materials, and the development of fabrication techniques for devices based on those materials, including solid oxide fuel cells (SOFC) and gas separation membranes. At present, his primary responsibility is leadership of PNNL’s SECA Core Technology Program (SOFC) materials development activities. In this role, he directs work in a number of areas, including cathode and anode materials, alloy interconnect materials, protective coatings for alloy interconnects, contact and sealing materials for SOFC stacks, and cost-effective cell fabrication techniques.
