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 ...

Interplay between the potential waveform and diffusion layer dynamics determines the time-response of voltammetric detection in microchannels

Martinus Gijs, Raphaël Etienne Jean Trouillon

The diffusion layer is a critical factor affecting the temporal response of electrochemical devices. In this article, we have investigated the effect of the relaxation of the diffusion layer during the potentiodynamic sensing of ferrocenemethanol (FcMeOH) ...

Robust production of purified H-2 in a stable, self-regulating, and continuously operating solar fuel generator

Sophia Haussener, Miguel Antonio Modestino

The development of practical solar-driven electrochemical fuel generators requires the integration of light absorbing and electrochemical components into an architecture that must also provide easy separation of the product fuels. Unfortunately, many of th ...

Photo-Ionic Cells: Two Solutions to Store Solar Energy and Generate Electricity on Demand

Hubert Girault, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon

A solar energy conversion concept based on the photo-induced separation of a pair of redox species in a biphasic liquid cell is presented. The redox pair is subsequently discharged in an electrochemical flow cell to generate electricity. To illustrate this ...

Local Activation and Degradation of Electrochemical Processes in a SOFC

Jan Van Herle, Zacharie Wuillemin, Hossein Madi, Yannik Antonetti

The local electrochemistry is studied in a SOFC repeat-element using a test setup that allows a local control of the polarization. During long-term tests, the local current densities evolve, following activation and degradation periods. Electrochemical imp ...

The Transient Photocurrent and Photovoltage Behavior of a Hematite Photoanode under Working Conditions and the Influence of Surface Treatments

Michael Graetzel, Kevin Sivula, Florian Le Formal

Hematite (alpha-Fe2O3) is widely recognized as a promising candidate for the production of solar fuels via water splitting, but its intrinsic optoelectronic properties have limited its performance to date. In particular, the large electrochemical overpoten ...
