Graph Chatbot
Chattez avec Graph Search
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 paper describes a test set-up, based on the use of a Digital Signal Processor (DSP), developed for the evaluation of the operational characteristics of an autonomous Auxiliary Power Unit (APU). The considered APU includes a 4.8 kW commercial Proton Exc ...
If fuel cell technology – with its inherent benefits of high efficiency and low emissions – is to be used in decentralised power sources, in mobile or transportation applications, the systems have to be able to adapt to fast load changes and varying operat ...
When running a fuel cell system in load following mode, several operating points (i.e. a combination of gas flow rates, pressures, humidities, temperatures and current density) can provide the required net power. Typically, only one of those operating poin ...
Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. Best results are typically achieved using model based control strategies. This paper elaborates a control oriented PEM fuel cel ...
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 ...
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 ...
We optimize the preparation of BZY20 and BCY10 by a wet chemistry route (the polyacrylamide gel process) and mixed oxide route, respectively. For both materials, the purity of powders drastically depends on the annealing conditions of the raw materials. Pu ...
This paper presents the modeling strategy developed for the design of a planar solid oxide fuel cell repeat element. Design goal are to reach good performance (power density) and reliability (ie. limit risk of failure and degradation). This challenging pro ...
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 ...
Proton exchange membrane (PEM) fuel cells show characteristics of high power density, low operating temperature, and fast start-up capability, which make them potentially suitable to replace conventional power sources (e.g., internal combustion engines) as ...
