Parametrical analysis of a tubular pressurized SOFC

High temperature fuel cells of the solid oxide type (SOFC) are simple electrochemical devices that operate at 1000 o C and are capable of con- verting the chemical energy of natural gas to AC electric power at approxi- mately 55-60% efficiency (net AC/LHV in atmospheric pressure). In this paper, a zero-dimensional model of a single tubular SOFC with internal reforming of hydrocarbons is proposed which has been both numerically implemented and parametrically analyzed.
