Vignettes in Solid State Electrochemistry for Sustainable Energy Technologies

Electrochemistry plays a central role in the interconversion between electrical energy and chemical compounds. Moreover, many technological devices, including fuel cells, electrolyzers, and batteries, rely on solid state materials to facilitate the electrochemical conversions of interest. Here we describe advances in the science and engineering of intermediate temperature electrochemical systems, focusing in particular to those based on the electrolytes cesium dihydrogen phosphate, a proton conductor, doped barium zirconate, also a proton conductor, and doped ceria, an oxygen ion conductor. Each offers unique challenges and opportunities in the context of sustainable energy solutions.

About Sossina M. Haile

Sossina M. Haile is the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University, a position she assumed in 2015 after serving 18 years on the faculty at the California Institute of Technology. She earned her PhD degree in materials science and engineering from the Massachusetts Institute of Technology in 1992 and spent two years (1991-1993) at the Max Planck Institute for Solid State Research in Stuttgart, Germany, first as a Fulbright Fellow, then as a Humboldt Fellow. Haile’s research broadly encompasses materials, especially oxides, for sustainable electrochemical energy technologies. Her work in fuel cell science and technology has pushed the field to new insights and record performance metrics. In parallel, she has created new avenues for harnessing sunlight to meet rising energy demands.

Haile has published approximately 200 articles and holds 14 patents on these and other topics. Amongst her many awards, in 2008 Haile received an American Competitiveness and Innovation Fellowship from the U.S. National Science Foundation in recognition of “her timely and transformative research in the energy field and her dedication to inclusive mentoring, education and outreach across many levels.” In 2010, she was the recipient of the Chemical Pioneer Award (American Institute of Chemists); in 2012, the International Ceramics Prize (World Academy of Ceramics); and in 2020, the David Turnbull Lectureship (Materials Research Society). She is a fellow of the Materials Research Society, the American Ceramics Society, the African Academy of Sciences, and the Ethiopian Academy of Sciences, and serves on the editorial boards of Materials Horizons, Annual Review of Materials Research and Joule. Her professional service includes past membership on the board of the Materials Research Society, and current membership on the board of Ethiopia Education Initiatives.
