    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
