Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The performance of portable power generation systems is a major limitation on the freedom and amount of utility provided by portable electronic devices. In that respect, fuel cells are a promising alternative to current state-of-the-art batteries as there ...
This dissertation reports on the development of devices and concepts for electrical and microfluidic cell manipulation. In the present context, the term cell manipulation stands for both cell handling and cell modification. The combination of microfluidic ...
Pt nanoparticles were synthesized by the H2O-in-oil (w/o) microemulsion technique and deposited onto B-doped diamond (BDD) electrodes. TEM showed that Pt particles size is limited to 2-5 nm range with narrow distribution. Anodic treatment at high overpoten ...
Results concerning the coupling of the steam reforming and total oxidn. of methanol in a two-passage reactor are presented. A com. available copper-based catalyst is used for the steam reforming. For the total oxidn., a highly active cobalt oxide catalyst ...
The aim of this project was to develop and implement an optimisation methodology that combines process thermo-modelling and process integration in a thermo-economic optimisation framework for fuel cells systems. During this project, a generic software has ...
Bimetallic Pt/Sn nanoparticles, synthesized by the microemulsion method, have been investigated once deposited on a boron-doped diamond (BDD) substrate electrode. Nanoparticles are in the nano-size domain and their effective composition corresponds to thei ...
If process modelling is a well known approach to compute the performances of fuel cell systems, the optimal design of systems where the process configuration is not fixed a priori remains an issue. The goal of the presented methodology for integrating and ...
Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. In order to design such a controller, a simple PEFC system model describing all the important system dynamics and cross couplin ...
A method that combines process modelling and process integration techniques has been developed to tackle the design of complex integrated systems like fuel cell systems. This method uses the equations of the composite curves as constraints to model the ide ...
We report the detection of protein molecules with nanofabricated pores using the resistive pulse sensing method. A 20-nm -thick silicon nitride membrane with a nanofabricated pore measuring about 55 nm in diameter separated an electrolyte cell into two com ...
