Moving away from conventional solid oxide electrolytes, hybrid fuel cells based on composite electrolytes (a solid oxide electrolyte and a molten alkaline carbonate phase) exhibit promising performance due to the high electrolyte conductivity within the so-called intermediate temperature ranges (400-600 C). These electrolytes are a blend of those traditionally used in Solid Oxide and Molten Car...
Emergy indicators of the industrial production and pilot-plant operation of Molten Carbonate Fuel Cells (MCFC) are presented, as a continuation of ongoing research on Hydrogen-based technologies. MCFCs are very likely to shortly reach the commercialization phase, as a result of the recent intense efforts in the development of innovative ceramic components (anode, cathode and matrix), as well as...
بحران انرژی یکی ازموضوعاتی است که به شدت مورد توجه جوامع امروزی می باشد. سوختهای فسیلی که تاکنون تامین کننده بخش عمده ای از انرژی مورد نیاز بشر بوده اند، منابعی رو به زوال هستند. از طرفی، سیستمهای مصرف کننده این سوختها دارای بازده پایینی می باشند. این سیستمها، علاوه بر اتلاف منابع سوختی، از مهمترین منابع آلوده کننده محیط زیست نیز محسوب می شوند. از این رو، استفاده از انرژیهای نو و سیستمهای تبد...
Various models have been devoted to the operation mechanism of porous diffusion electrodes. They are, however, suffering from the lack of accuracy concerning the acid-film thickness on which they are based. In the present paper the limiting current density has been measured for oxygen reduction on polytetrafluorine-ethyl bonded gas-diffusion electrodes in phosphoric acid with and without fluori...
In this paper, a hybrid system, obtained by integrating a molten carbonate fuel cell with a micro-turbine is considered. The size of the plant is selected on the basis of the maximum biogas production registered by monitoring annual operation of an operating anaerobic digestion plant. The hybrid system produces electricity and supplies heat to the digester. Heat is necessary to keep correct ope...
