Thermodynamic Theory of SOFC Hybrid Systems

Carnot cycle for heat management of the fuel cell 

The fuel cell FC delivers the reversible work Wipcrev 

FC is the heat source of the Carnot cycle CC and delivers reversible heat qpcrev The reversible work w ccrev of CC is defined by 

The heat pump HPF has to deliver the reversible heat qnppnv to heat the fuel 

HPF has to be supplied reversibly with the work Wtupprev that is equal to the exergy eppc of the fuel with the thermodynamic state of the fuel cell and the heat Happrev from the environment
