FUEL CELL SYSTEM AND STARTUP METHOD OF FUEL CELL AT LOW TEMPERATURE

摘要

PPROBLEM TO BE SOLVED: To improve startability and power generation stability of a fuel cell on startup below freezing point after a bit operation (on startup in a state that an ignition switch is turned off after a startup below freezing point before warning up inside the fuel cell, and the ignition switch is again turned on in a state currently below freezing point or in a state continuously below freezing point). PSOLUTION: When restarting up after the bit operation below freezing point, further increases in pressure at the anode side, pressure at the cathode side, and flow rate at the cathode side are performed in comparison to the usual startup control below freezing point.
