Ce document a pour but de rendre compte de quelques avancees recentes concernant les schemas volumes finis (dits egalement centres ou colocalises) pour l'hydrodynamique Lagrangienne. Il est structure en trois parties. La premiere partie, introductive, est un survol des elements de modelisation et d'analyse numerique qui ont motive le developpement ...

We define and solve equations describing the equilibrium partitioning of nitric acid (HNO_3) and water (H_2O) between the gas phase, liquid NH_3/H_2SO_4/HNO_3/H_2O aerosols, and ice crystals. The calculations are based on recently published parameterizations of the saturation vapor pressures of HNO_3 and H_2O over the quarternary solutions, which a...

Besides aspects like lifetime, efficiency or environmental compatibility, the question of the attainability of given cost targets is of paramount interest in fuel cell technology. Therefore, a major main of this PhD thesis is to develop a universally valid techno-economic cost model for components of PEFC stacks in the kilowatt range. Different tec...
