Abstract
A fuel cell power plant and a process for operating a series of molten carbonate fuel cells in the fuel cell power plant are described. In the fuel cell power plant, cathode feed gas at required cathode feed temperature is introduced into the cathode inlet of the first fuel cell of the fuel cell series. The cathode exhaust gas from the first fuel cell and the cathode exhaust gas from the exhaust outlet of each successive fuel cell is introduced to the cathode inlet of the next fuel cell downstream thereof. The cathode feed temperature to the inlet of each fuel cell after the first fuel cell is maintained at the desired level by adding a reactant-containing gas to the cathode side exhaust between each pair of consecutive fuel cells in the series. The added reactant-containing gas is at a lower temperature than the cathode side exhaust to which it is added, whereby desired cathode feed temperature to the inlet of each successive fuel cell downstream of the first fuel cell is achieved.
