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 ...
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 ...
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 Note is to predict by means of large eddy simulations the three-dimensional structures and secondary mass and heat fluxes which develop within a heated curved duct, for applications to rocket engines cooling channels. We show the existence ...
A modern version of the indirect ex-cell electrolytic oxidn. of arom. compds. is presented in which: (1) a slurry of Mn2(SO4)3 in concd. H2SO4 is used as O carrier in the presence of a mixt. of catalysts to increase the current efficiency for the electroch ...
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 ...
Electrolysis cell with a bipolar electrode is described. The bipolar electrode in this electrolytic cell comprises a substrate coated with doped diamond electroconductive film. [on SciFinder (R)] ...
