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.
This paper presents a methodology for the optimal design and operation of man-portable power generation devices based on fuel cells. To illustrate the methodology, we focus on a simple process that consists of a fuel processing reactor, a solid-oxide fuel ...
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 ...
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 ...
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 ...
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 ...
A downscaled drive train with a 6.5 kW fuel cell and a 10 kW supercapacitor module was realized and tested. The voltage levels and the energy flow between fuel cell and supercapacitor were controlled by an electronic unit. The combined fuel-cell/supercapac ...
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 ...
In the attempts to attain greater efficiency of mobility, based in the long-term on renewable energy sources, the efficiency of energy conversion in the vehicle remains an important issue. Polymer electrolyte membrane fuel cell technology has the potential ...
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 ...
A model of a system including a proton exchange membrane (PEM) fuel cell and its fuel processing section has been developed. The goal was to investigate the process configurations to identify the optimal operating conditions and the optimal process structu ...
