By combining a gas turbine with solid oxide fuel cells (SOFCs), inefficiency and
incomplete fuel consumption of SOFCs can be compensated
Please, see [6] for details and mass and energy balances
Mechanism of electricity generation in a solid oxide fuel cell
with an internal methane conversion into H2 and CO (syngas)
A heat release (fuel cells inefficiency) and incomlete fuel consumtion in SOFC are compensated by the power generated with turbine
