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.
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 ...
The Industrial Electronics Laboratory at the Swiss Federal Institute of Technology (EPFL) in Lausanne has built a prototype of a revolutionary two-wheeled vehicle. Due to its configuration with two coaxial wheels, each of which is coupled to a DC Motor, th ...
Le cursus universitaire des étudiants de l'EPFL comprend, outre des cours magistraux, des travaux dirigés et des ravaux pratiques, la réalisation de projets de semestre et de diplômes. Les étudiants ont ainsi l'occasion, au travers de ces projets, soit de ...
This paper presents a hybrid energy storage system based on Compressed Air Energy Storage (CAES), where the extraction of energy is done within maximum efficiency conditions. As the maximum efficiency conditions impose the level of converted power, an inte ...

Maintaining a fuel cell (FC) system in correct operating conditions when subjected to fast load changes requires good system control. The best results are typically achieved using model-based control strategies. This paper elaborates a control-oriented pro ...
Correctly controlling a fuel cell system and maintaining correct operating conditions, particularly under dynamic load variations, is difficult without advanced, multivariable control systems. In order to design and implement such controllers, an appropria ...
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 ...
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 ...
