4. Development and characterization of functional composite materials for advanced energy conversion technologiesDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. LÄS MER
5. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine SystemsDetta är en avhandling från Department of Heat and Power Engineering, Lund university
Sammanfattning : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. LÄS MER
