A comparison of impedance based characterization and modeling of high and low temperature fuel cells and electrolyzers

PD Dr.-Ing. André Weber is Academic Senior Councillor and leads the Batteries, Fuel Cells and Electrolysis group at KIT's Institute for Applied Materials - Electrochemical Technologies (IAM-ET) in Karlsruhe, Germany.

His research focuses on the characterization and modeling of electrochemical energy converters and storage devices across multiple scales - from the electrochemical and microstructural properties of porous electrodes to the performance and lifetime analysis of engineered cells and the dynamic behavior of full systems, covering both high-temperature fuel cells/electrolyzers (SOFC/SOEC) and low-temperature polymer electrolyte systems (PEMFC/PEMEL) as well as lithium-ion and solid-electrolyte batteries.

Position & Research Group

PD Dr.-Ing. André Weber is Academic Senior Councillor at the Institute for Applied Materials - Electrochemical Technologies (IAM-ET), Karlsruhe Institute of Technology (KIT), where he heads the Batteries, Fuel Cells and Electrolysis research group.

Research Focus

  • Characterization and modeling of electrochemical energy converters and storage devices
  • Electrochemical and microstructural properties of porous electrodes
  • Performance and lifetime analysis of engineered cells
  • Dynamic behavior of complete electrochemical systems

Application Areas

  • High-temperature fuel cells and electrolyzers (SOFC, SOEC)
  • Low-temperature polymer electrolyte systems (PEMFC, PEMEL)
  • Lithium-ion and solid-electrolyte batteries
  • Nonlinear Frequency Response Analysis (NFRA) for online lithium plating detection

Impedance-Based Characterization Across Technologies

A central theme of his research is the use of impedance-based methods to characterize and model electrochemical systems consistently across very different operating regimes, allowing direct comparison between high- and low-temperature fuel cells and electrolyzers as well as battery systems.

Biomedical Engineering in Uruguay and the EU-Mercosur Partnership Agreement: the case of Bioimpedance and Ionizing Technologies

Prof. Franco Simini is Professor of Biomedical Engineering and Medical Informatics at the Universidad de la República, Uruguay, where in 1985 he founded the Núcleo de Ingeniería Biomédica (NIB), a joint department of the Medical and Engineering Faculties. He trained as an electrical engineer, with studies at the University of Pisa, Italy, and holds a doctorate in electrical engineering.

His research centres on low-cost solutions to clinical problems, including electrical impedance tomography for monitoring pulmonary oedema (IMPETOM), non-invasive reduction of intra-abdominal pressure (ABDOPRE), biomechanics instrumentation, and medical informatics. He is co-designer of the Perinatal Information System (SIP), long used across Latin America and the Caribbean. Named Outstanding Engineer in Uruguay (2022) and a member of the National Academy of Engineering of Uruguay (2025), he is an IEEE Life Senior Member active in technology transfer, university governance, and the organisation of major international biomedical engineering congresses.

Education & Early Career

Franco Simini trained as an electrical engineer, with studies at the University of Pisa, Italy, and holds a doctorate in electrical engineering. Early in his career he designed the Perinatal Information System (SIP) for PAHO/WHO, a pioneering record of pregnancies and births used across the Americas from the 1980s onward.

Academic Career & Leadership

In 1985 he founded the Núcleo de Ingeniería Biomédica (NIB) at the Universidad de la República, a joint department of the Medical and Engineering Faculties, which he continues to coordinate. He has directed some 120 biomedical engineering and medical informatics projects and theses, created nine postgraduate courses, and published books on biomedical engineering, bioimpedance, and medical engineering. He was also a founding committee member (2008–2013) of the University's Espacio Interdisciplinario.

Research Focus

  • Electrical impedance tomography for lung monitoring (IMPETOM)
  • Non-invasive reduction of intra-abdominal pressure (ABDOPRE)
