The cathode/electrolyte LSCF48/YDC15 couple is a building block of a new innovative and competitive design of a high temperature fuel cell, operating in the range between 600 and 700°C. It is based on the idea for a junction between a proton conducting SOFC (PCFC) anode/electrolyte part and a SOFC cathode/electrolyte part through a mixed H and O conducting porous ceramic membrane. Thus, in this...

The operation of Fuel Cell Distributed Generation (FCDG) systems in distribution systems is introduced by modeling, controller design, and simulation study of a Solid Oxide Fuel Cell (SOFC) distributed generation (DG) system. The physical model of the fuel cell stack and dynamic models of power conditioning units are described. Then, suitable control architecture based on fuzzy logic contro...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...

This paper presents a hydrogen powered hybrid solid oxide fuel cell-steam turbine (SOFC-ST) system and studies its optimal operating conditions. This type of installation can be very appropriate to complement the intermittent generation of renewable energies, such as wind generation. A dynamic model of an alternative hybrid SOFC-ST configuration that is especially suited to work with hydrogen i...

Our interest in the exchange reaction of oxygen between the gas phase and oxides is twofold: (i) to understand the mechanistic details of one of the "simplest" gas-solid reactions which nevertheless exhibits an astonishing complexity in terms of reaction pathways, (ii) to use this knowledge for improving electrochemical devices which rely critically on a fast oxygen incorporation rate such as c...

Fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. The first objective of this contribution is to find a suitable reduced model of a Solid Oxide Fuel Cell (SOFC). The derived reduced model is then used to design a state estimator. I...
