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 ...
EPFL2024Degradation study of a reversible solid oxide cell (rSOC) short stack using distribution of relaxation times (DRT) analysis
Jan Van Herle, Stefan Diethelm, Philippe Aubin, Suhas Nuggehalli Sampathkumar, Maria del Mar Perez Fortes
Reversible solid oxide cells (rSOC) can convert excess electricity to valuable fuels in electrolysis cell mode (SOEC) and reverse the reaction in fuel cell mode (SOFC). In this work, a five - cell rSOC short stack, integrating fuel electrode (Ni-YSZ) suppo ...
PERGAMON-ELSEVIER SCIENCE LTD2022The impacts of the gas diffusion layer contact angle on the water management of the proton exchange membrane fuel cells: Three-dimensional simulation and optimization
Jan Van Herle, Hossein Pourrahmani
Water management of the proton exchange membrane fuel cell (PEMFC) is an important parameter to improve efficiency, especially in cold weather conditions. The generated water of the electrochemical reactions inside PEMFC may stay inside the cell and fill t ...
WILEY2022Performance Analysis of Ammonia in Solid Oxide Fuel Cells
Jan Van Herle, Suhas Nuggehalli Sampathkumar, Peter Hugh Middleton, Steve Joris
Ammonia (NH3) has 17.8 wt% hydrogen and is easily liquified at 25°C and 8 bar pressure. Ammonia is carbon-free and can be produced sustainably at large scale and low cost. Solid oxide fuel cells generate electricity with efficiencies greater than 60% and c ...
ECS2021In-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 ...
2020Analysis of High Temperature Degradation of Alloys in Solid Oxide Fuel Cell
Solid oxide fuel cells (SOFCs) are approaching commercialization to improve power production efficiency. Currently, cost and lifetime reliability limit their spread in the market. The SOFC is ceramic-based, but refractory metal alloys are in fact the major ...
EPFL2019Degradation analysis of commercial interconnect materials for solid oxide fuel cells in stacks operated up to 18000 hours
Despite being a mature technology, solid oxide fuel cell (SOFC) devices are still limited by lifetime issues. In SOFC stacks, cell/interconnect interaction is the main responsible for voltage degradation at the oxygen electrode side. Corrosion and chromium ...
2019Enforcing optimal operation in solid-oxide fuel-cell systems
Dominique Bonvin, Jan Van Herle, Christophe Salzmann, Timm Faulwasser, Zacharie Wuillemin
This paper describes an optimization strategy for operating solid-oxide fuel-cell systems at optimal efficiency. Specifically, we present the experimental validation of a real-time optimization (RTO) strategy applied to a commercial solid-oxide fuel-cell s ...
2019Monitoring and Diagnostics of SOFC Stacks and Systems
Jan Van Herle, Stefan Diethelm, Priscilla Caliandro
While high performance of SOFC systems has already been achieved, there is still a need to increase the stack lifetime, while decreasing the system's total cost of ownership, both being linked. The increase in lifetime includes the minimization of performa ...
2019Improved thermo-mechanical reliability of anode-supported solid oxide fuel cells
Solid oxide fuel cell (SOFC) based systems are co-generators of electricity and heat that excel for their high efficiency, low pollutant emissions and fuel flexibility. Their reliability is close to meet the requirements for market deployment. Recent resea ...
