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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Fuel Cells are destined to supply electric energy beginning from primary resources. A static DC-AC converter is necessarily inserted between the fuel cells and the distribution network. This paper describes a new P.W.M. strategy for a current source invert ...
Three labs at EPFL which are bound through CRETE (Centre de Recherche et d’Enseignement en Technologies Energétiques) have oriented some of their research activities on integrated fuel cells equipment. Technological and systemic optimisation research progr ...
