An opportunity exists for an experienced Research Scientist with a background in materials science and engineering to support NETL’s solid oxide fuel cell (SOFC) research. Research efforts will focus primarily on: (1) electrode engineering technology; (2) examination of electrode degradation processes; (3) fundamental reaction and transport measurements. Researcher will design and conduct experiments, complete literature surveys and generate or support generation of review frameworks and research papers, all the while collaborating in an integrated team research environment.
Primary Responsibilities Include:
- Standardized electrode manufacturing methods will be developed and employed by utilizing conventional and advanced ceramic processing methods in conjunction with various team efforts to understand electrode reaction and degradation mechanism, and to develop degradation models.
- Tailored materials and methods for electrode nano-engineering will be developed at a button cell scale and will also be evaluated at the commercial stack scale to ensure proper performance and sufficient potential to continue development.
- A series of candidate electrocatalyst materials will be selected for insertion into the cathode or anode microstructure to effect an improvement in cell performance, measured by techniques that investigate electrode activity, stability, and degradation.
- Long-duration exposure testing coupled with detailed ex-situ spectroscopy and electron microscopy to examine degradation arising from inherent impurities.
- Novel electrode and electrocatalyst materials will have their electrochemical properties characterized, as well as the degradation of those properties. The fundamental characterization of these materials will aid in materials selection and inform the long term SOFC degradation models being developed at NETL.
- PhD in Materials Science and Engineering or related field with 2 years prior relevant experience; demonstrable skill in conducting laboratory experiments and will possess knowledge of conventional techniques of electrochemical performance testing (e.g. cyclic voltammetry, V-I curve generation, Electrochemical Impedance Spectroscopy, Ionic Conductivity, and Electrical Conductivity Relaxation).
- Experience in basic ceramic processing such as powder synthesis, tape casting, screen printing, and sintering.
- Experience in wet chemistry methods, and basic understanding of the general principles of fuel cell operation.
- Experience in microstructure analysis with SEM, EDS, AFM, etc., and sample preparation for the analyses.
- Experience in designing and constructing model experiment setup.
- Possess excellent communication skills and will possess demonstrable experience completing research in a collaborative/team environment.
- Knowledge of conventional and state-of-the-art fuel cell systems, including the factors limiting fuel cell performance and common degradation phenomena in SOFCs.
- Scanning electron microscopy, including sample preparation and the analysis of microstructure and local composition within porous electrodes.
- Phase identification using x-ray diffraction and/or vibrational spectroscopy.
