... management of coal based SOFC-GT hybrid systems is accomplished by the careful control of the cathode air stream within the fuel cell (FC). Decoupled centralized and dynamic decentralized control schemes are tested for one critical airflow bypass loop to regulate cathode FC airflow and modulation of turbine...

... natural gas, so given the same turbine inlet temperature there will be an increase in the turbine shaft torque, which is limited. Note that for Case 3 lowering the fuel utilization will also decrease the cathode recycle since the compressor outlet temperature will be higher (from gas compression heating...

...Eric A. Liese; Randall S. Gemmen Solid Oxide Fuel Cell (SOFC) developers are presently considering both internal and external reforming fuel cell designs. Generally, the endothermic reforming reaction and excess air through the cathode provide the cooling needed to remove waste heat from the fuel...
