OPERATING METHOD FOR MOLTEN CARBONATE FUEL CELL

摘要

PURPOSE: To decrease the dispersion of temperature distribution and retain cell life for a long time without adversely affecting cell performance in the operation of a molten carbonate fuel cell. CONSTITUTION: Supply of cathode gas is increased in a high temperature part on the inside of a cell than a low temperature part. The filling amount of a catalyst is increased on a fuel gas outlet side than a fuel gas inlet side, a cathode gas flow rate on the inside of the cell is increased on an anode gas flow path outlet side than an anode gas flow path inlet side, and the difference between the maximum temperature on the inside of the cell and the minimum temperature is controlled within 150 deg.C.
