Electricity from ethanol fed SOFCs: the expectations for sustainable development and technological benefits
(2004)Based on a thermodynamic and economic analysis presented in the first part of this paper, ethanol is considered as an alternative fuel with suitable characteristics for electricity generation in SOFCs. Ethanol fed steam ... -
Exergy Analysis of an Intermediate Temperature Solid Oxide Fuel Cell-Gas Turbine Hybrid System Fed with Ethanol
(2012)In the present work, an ethanol fed Solid Oxide Fuel Cell-Gas Turbine ( SOFC-GT) system has been parametrically analyzed in terms of exergy and compared with a single SOFC system. The solid oxide fuel cell was fed with ... -
Heat transfer phenomena in a solid oxide fuel cell: An analytical approach
(2005)The steady-state heat transfer problem within a fuel cell is considered here. The original 2-D problem is defined while an averaging technique is used in order to reduce its dimensions to one. The full heat transfer equations ... -
