Fuel cell power plants description

The cell stack assembly is the heart of the power plant which produces both electrical and thermal energy by electrochemically combining H2 in fuel and O2 in air. The basic description of a phosphoric acid fuel cell is shown in Fig. 12.2. 

Chan et al. [25] modeled a part load operation of a solid oxide fuel cell-gas turbine hybrid power plant. This paper contains a centrifugal compressor model and axial turbine. The system generated 1.7 MW at 60% efficiency. The turbine inlet temperature was 1036°C at a pressure ratio of 3. This paper contains no detailed model description of an SOFC module and ejector.
