2. 1. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

   Author : Jens Pålsson; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Gases; fluid dynamics; plasmas; plasma; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; Modelling; Mechanical engineering; Solid oxide fuel cell; Hybrid system; Gaser; fluiddynamik;

   Abstract : 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. READ MORE
