Evolution of the Morphology Near Triple-Phase Boundaries in Ni–Yttria Stabilized Zirconia Electrodes Upon Cathodic Polarization

Jan Van Herle, Marco Cantoni, Guillaume Jeanmonod, Lucie Navratilova, Arata Nakajo, Priscilla Caliandro, Giorgio Rinaldi

Microstructural changes in Ni–yttria stabilized zirconia (YSZ) near the YSZ electrolyte were examined by three-dimensional (3D) electron microscopy after electrolysis and fuel cell operation up to 10,700 h and 15,000 h, respectively. The depletion of Ni an ...

In-situ experimental benchmarking of solid oxide fuel cell metal interconnect solutions

Jan Van Herle, Stefan Diethelm, Priscilla Caliandro, Manuel Bianco

The progress in the diffusion of solid oxide fuel cell (SOFC) as commercial devices is not paired by literature production. Articles describing the behaviour of SOFC stacks are rare because of confidentiality reasons for commercial suppliers while research ...

Effects of Polarization on the Microstructural Changes at the YSZ/Ni-YSZ Interface

Jan Van Herle, Lucie Navratilova, Arata Nakajo, Priscilla Caliandro, Giorgio Rinaldi

This study examines the effect of Ni migration near the interface with the electrolyte after fuel cell (SOFC) and electrolysis mode (SOEC) operation on nickel-yttria stabilized zirconia (Ni-YSZ) electrodes. The experimental dataset consists in a series of ...

Model-assisted identification of solid oxide cell elementary processes by electrochemical impedance spectroscopy measurements

Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro

Electrochemical Impedance Spectroscopy (EIS) is extensively used to characterize Solid Oxide Cells (SOCs) to extract information on the elementary loss mechanisms. However, these individual mechanisms usually overlap in the frequency domain, requiring dedi ...

Triode Solid Oxide Fuel Cell Operation Under Sulfur-Poisoning Conditions

Jan Van Herle, Stefan Diethelm, Priscilla Caliandro

The triode solid oxide fuel cell (SOFC) is a three electrodes configuration. The third electrode, so-called auxiliary, is connected in a way to run in electrolysis mode, while cathode and anode operate in normal fuel cell mode. This mixed operation allows ...

A linear programming approach to the optimization of residential energy systems

Jan Van Herle, Daniel Kuhn, Dirk Lauinger, Priscilla Caliandro

A decision-support tool (ORES) in the form of a linear program is developed to determine the optimal investment and operating decisions for residential energy systems. It shows how energy conversion units such as a cogeneration fuel cell, a heat pump, a bo ...

Electrochemical Model of a Triode Solid Oxide Fuel Cell

Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro

A Triode Solid Oxide Fuel Cell is a novel cell architecture that consists of two circuits: an auxiliary circuit, operated in electrolysis mode, and a conventional main fuel cell circuit. During triode operation, performance enhancement can be expected espe ...
