in this study the characteristics of two different kinds of la0.6sr0.4co0.2fe0.8o3 (lscf) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from fuel cell materials co. (fcm co., usa), were compared. the co-precipitated powder was prepared by using ammonium carbonate as precipitant with a nh4+/no3- molar ratio of 2 and calcination at 1000c for 1 h....

The main aim of this paper is development of renewable energy sources in distributed generation (DG) systems. A fuel cell (FC) is considered as a promising power generating sources for DG system. In this paper, a mathematical analysis of Solid Oxide Fuel Cell is carried out for extensive MATLAB/Simulink modeling. For the transient analysis of SOFC distributed generation system, a AC/DC load is ...

A deep analysis of the Fuel Cells technologies state of the art has been done in this article. After a general description of the fuel cell base structure the six most important fuel cell technologies Polymeric Electrolyte Membrane Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC), Alkaline Fuel Cells (AFC), Phosphoric Acid Fuel Cell (PAFC), Molten Carbonate Fuel Cell (MCFC), Solid Oxide Fu...

This study shows the design of a new hybrid power generation system, photovoltaic panel (PV)–coupled solid oxide fuel cell (SOFC) and gas turbine (GT)–electrolyser. Three objectives (cost, pollutant emissions, and reliability), which are usually in conflict, are considered simultaneously. The design of a hybrid system, considering the three mentioned objectives, poses a very complex problem of o...
