Alba Garzón Manjón How Can We Encourage More Widespread Use of Hydrogen Fuel Cells?
Max-Planck-Institut für EisenforschungDüsseldorf
Novel alloys for automotive lightweight design and airplane turbines, materials for sustainable energy conversion and storage, and the development of big data and machine learning methods – these are just a few examples of the research areas that are being investigated by the scientists of the Max-Planck-Institut für Eisenforschung. The team of engineers, material scientists, physicists, and chemists develops tailored materials and methods for mobility, energy, infrastructure, and information. To this end, the researchers study complex materials with atomic precision under real environmental conditions.
Department of Structure and Nano- / Micromechanics of Materials
Plasticity, fatigue, and fracture of materials are usually initiated by local deformation processes.
The mission of the Department Structure and Nano-/Micromechanics is to develop experimental methods to perform quantitative nano-/micromechanical and tribological tests for complex and miniaturized materials,
to unravel the underlying deformation mechanisms by advanced microstructure characterization techniques from the micrometer level down to atomic dimensions, to establish material laws for local and
global mechanical behavior, and finally to generate nanostructured materials and high temperature intermetallic materials with superior mechanical properties. The in-depth microstructure investigations
include atomic resolved high-resolution (scanning) transmission electron microscopy (STEM/TEM), analytical and conventional TEM, scanning electron microscopy with electron backscattered diffraction (SEM/EBSD),
focused ion beam microscopy (FIB), X-ray diffraction and synchrotron radiation techniques. A cornerstone will be the combination of advanced characterization and mechanical testing in form of in situ nano-/micromechanical experiments which will permit to simultaneously observe the microstructural changes while measuring the mechanical response. The gained insights will be used to quantitatively describe and predict the local and global material behavior and to design superior nanostructured materials and high temperature intermetallic materials by using local confinement effects.
The synthesis of miniaturized nanostructured materials will be done by thin film deposition techniques.
One very promising way of producing energy in an environmentally friendly manner is via hydrogen fuel cells. In this video, ALBA GARZÓN MANJÓN explains that a fundamental barrier to the widespread adoption of this technology is the prohibitive cost of the noble metals that act as catalysts in the fuel cell. Garzón Manjón’s research seeks to identify alternatives, centering her search on high entropy alloy materials. Highlighting the importance of the size, composition and stability of any material used, the research shows that a body centeredcubic structure which is high in chromium and cobalt and low in manganese is most suitable. The new catalyst is also shown to use less energy to initiate the reaction than noble alloys.
