Electrochemical devices and computer science: water/thermal management of proton exchange membrane fuel cells and electrolyzers in different scales
The current restrictions on the registration of combustion engines in different countries and the harmful impacts of fossil fuels on the environment and human health have motivated decision-makers to use batteries and/or fuel cells as alternatives for comb ...
EPFL2024Local electrochemical and thermal investigation of a segmented reversible solid oxide fuel cell and electrolyzer
Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Audrey Désirée Wesoly, Hamza Moussaoui
A novel setup has been designed and mounted to investigate the local electrochemical and thermal behavior of a cell from a 4-cell short stack under reversible operation solid oxide fuel cell/solid oxide electrolyzer (SOFC/SOE). It consists in the partition ...
Oxford2023Development of Highly Efficient Perovskite-on-Silicon Tandem Solar Cells
Crystalline Silicon (c-Si) solar cells are dominating the photovoltaic (PV) market. Owing to their large manufacturing capacity, reliability and efficiency, c-Si solar cells are now cost-competitive with other non-renewable electricity sources in many plac ...
EPFL2020Characterisation of Silicon Heterojunction Solar Cells Beyond Standard Test Conditions
The global photovoltaic market is mostly dominated by solar cells based on crystalline silicon (c-Si), which are covering 95% of the market. This thesis concerns silicon heterojunction (SHJ), a high-efficiency technology with a 2% market share in 2018, but ...
EPFL2020A Simple, Robust, and Low-Cost Method To Produce the PURE Cell Free System
Sebastian Maerkl, Barbora Lavickova
We demonstrate a simple, robust, and low-cost method for producing the PURE cell-free transcription translation system. Our OnePot PURE system achieved a protein synthesis yield of 156 peg/mL at a cost of 0.09 USD/ktL, leading to a 14-fold improvement in c ...
AMER CHEMICAL SOC2019Identification of Solid Oxide Cell Elementary Processes by Electrochemical Impedance Spectroscopy
The energy sector is undergoing several transformations in an effort to tackle climate change, driving society towards reducing energy consumption and more sustainable energy conversion. In this context, electrochemical devices such as Solid Oxide Cell (SO ...
EPFL2018Membrane electrode assembly fabricated with the combination of Pt/C and hollow shell structured-Pt-SiO2@ZrO2 sphere for self-humidifying proton exchange membrane fuel cell
Andreas Züttel, Heena Yang, Youngdon Ko
The Pt-supported hollow structured Pt-HZrO2 with the shell thickness of 27 nm is successfully synthesized. The water retention ability of Pt-HZrO2 is significantly enhanced compared with that of SiO2@ZrO2 due to the hydrophilic hollow structured HZrO2 with ...
Elsevier2017Energy Yield and Electricity Management of Thin-Film and Crystalline Silicon Solar Cells
In the case of high photovoltaic (PV) penetration into the electricity grid, the energy produced by a PV system that is effectively used (useful energy) depends on the energy yield and on how this energy is managed to avoid detrimental effects occurring at ...
EPFL2016Investigations into the Effects of Biofuel Contaminants on Solid Oxide Fuel Cells
Solid Oxide Fuel Cells (SOFCs) have gathered considerable attention as a clean, highly efficient conversion device for the production of both electricity and heat from fuels. Due to their high operating temperatures, SOFCs do not require pure hydrogen as f ...
EPFL2016Silver versus white sheet as a back reflector for microcrystalline silicon solar cells deposited on LPCVD-ZnO electrodes of various textures
Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, Etienne Antoine Julien Moulin
We compare the performance of two back reflector designs on the optoelectrical properties of microcrystalline silicon solar cells. The first one consists of a 5-mu m-thick low-pressure chemical vapor deposition (LPCVD)-ZnO electrode combined with a white s ...
