CONTROL OF FUEL REFORMER FOR FUEL CELL

摘要

PURPOSE:To obtain reformed gas of stable composition by inputting a detection signal of flue gas in addition to a detection temperature signal of a catalytic layer to a controller while utilizing said flue gas temperature signal as an arithmetic correction factor of a burner calory regulation output signal. CONSTITUTION:A temperature detector 11 of flue gas is provided on a flue 3' of a furnace 3 in addition to the temperature detector 8 of a catalytic layer 4 while inputting these detection signals to a controller 9a for operating the temperature of flue gas as a correction factor for the temperature signal of a catalytic layer 4 while regulating an opening degree of a burner fuel feeding valve 10 by its output. When the flue gas temperature exceeds the proper value as compared with the proper value, a control signal of suppressing the opening degree of the fuel feeding valve 10 is outputted to throttle the feeding valve 10 or stop an increase in the opening degree even before the catalytic layer temperature reaches the set value. Thereby, the temperature of the catalytic layer 4 is regulated while smoothly following the set value thus to quantatively and constitutionally stabilize the reformed gas to be fed to a fuel cell FC due to the stabilized reforming and reaction temperature.
