In diesem Artikel werden Ergebnisse der optimalen Steuerung eines SchmelzcarbonatBrennstoffzellensystems unter Lastwechseln präsentiert. Den umfangreichen Berechnungen liegt ein detailliertes, validiertes mathematisches Modell zugrunde, das die zeitliche und örtliche Dynamik der Gasströme, deren elektro-chemische Reaktionen und die in der Zelle herrschenden Temperaturen und elektrischen Spannun...

A Hybrid System based on High Temperature Fuel Cells coupled to a Microturbine allows a high efficiency, low environmental pollution and it may be exploited as a CHP System producing heat and electricity both Grid Connected and Stand Alone; the overall electrical efficiency could reach a very high value (up to 60%) and total efficiency could be over 70% including the contribution due to heat re...

Abstract Direct carbon fuel cell (DCFC) is a promising technology with high energy efficiency and abundant fuel. To date, variety of DCFC configurations have been investigated, molten hydroxide, carbonate or oxides being used as the electrolyte. Recently, there has particular interest in involved. The either an electrolyte catalyst different structures. In this review, we consider clue to discu...

Fuel cells offer the possibility of zero-emissions electricity generation and increased energy security. We review here the current status of solid oxide (SOFC) and polymer electrolyte membrane (PEMFC) fuel cells. Such solid electrolyte systems obviate the need to contain corrosive liquids and are thus preferred by many developers over alkali, phosphoric acid or molten carbonate fuel cells. Dra...

The Chariton Valley Biomass Power Project, sponsored by the U. S. Department of Energy Biomass Power Program, has the goal of converting switchgrass grown on marginal farmland in southern Iowa into electric power. Two energy conversion options are under evaluation: co-firing switchgrass with coal in an existing utility boiler and gasification of switchgrass for use in a carbonate fuel cell. Thi...
