Postdoc Position | Fundamental processes in next generation bipolar membranes
vor 3 Tg.

The Department of Interface Science headed by Prof. Beatriz Roldán Cuenya at the Fritz Haber Institute carries out cutting-edge research on advanced functional materials with applications in heterogeneous catalysis, energy conversion and electrochemistry.

By combining unique synthesis methods, state-of-the art tools for experimental characterization and advanced approaches to data analysis, atomistic details of thermal catalysis and electrochemical reactions at gas / solid and liquid / solid interfaces are revealed.

In particular, structure-reactivity correlations on nanostructured materials can be established, paving the way for the rational design of novel catalytic materials.

We are currently looking for a postdoctoral researcher (f / m / d) for the electrochemistry group at the Department of Interface Science.

Project : Fundamental processes in next generation bipolar membranes

Bipolar membranes can dissociate or form water (H++OH- H2O) at the interface between a proton and a hydroxide ion conductor under applied bias.

This ability enables bipolar membranes to maintain a pH gradient across an electrochemical device between the anode and the cathode and has led to their industrial application in electrodialysis.

Recently, we have made a major discovery that links the water dissociation catalysis occuring inside the bipolar membrane junction to water dissociation occuring on electrocatalyst surfaces.

This fundamental link shows that the bipolar membrane junction can also be used as a way to study operando water dissociation fundamentals.

The selected candidate will study fundamental processes in the bipolar membrane junction to better understand operando water dissociation and water formation.

To that end, collaborations with experts on operando (electro)catalyst characterization within the ISC department will be established.

  • Additionally, bipolar membranes are already being used industrially and have a wealth of future application, such as for fuel cells and electrochemical CO2 reduction;
  • a unique situation, where your fundamental insights have the potential for direct practical impact. In collaboration with other ISC team members you will therefore explore some of these emerging applications.

    The PostDoc position is initially for one year but can be extended up to three years.


    We expect candidates to have a :

  • A PhD degree in Chemistry, Chemical Engineering, Physical Chemistry or Physics, preferably with a specialization in Electrochemistry.
  • A strong publication record in peer-reviewed journals.
  • Experience at performing complex electrochemistry experiments with a high drive to solve scientific and practical / instrumental challenges independently.
  • Experience working with membrane electrode assemblies and Multiphysics simulations (e.g. COMSOL) is preferred.
  • Collaborative spirit and excellent English skills.
  • Application

    Please submit your application via our online application portal as soon as possible but latest by June 30, 2021 including the following documents :

  • Curriculum vitae
  • List of publications
  • Names and email addresses of three references
  • For more information, please contact
