Resumen de: US2018269505A1

A method for controlling a pressure drop across the anode side or the cathode side of a fuel cell stack by controlling the intrusion of a cell separator into the flow channels in a feeder region of the stack so as to create a larger pressure volume on a pressure bias side of the stack. The method controls the flow rates of one or both of the cathode and anode reactant gases so as to cause the cell separators in an inlet feeder region and/or an outlet feeder region to move relative to the anode side and the cathode side so as to change a flow volume in the inlet feeder region and/or the outlet feeder region to control the pressure drop.

FUEL CELL SYSTEM AND CONTROL METHOD THEREFOR

NºPublicación: DE102018100027A1 20/09/2018

Solicitante:
TOYOTA MOTOR CO LTD [JP]

Resumen de: US2018269504A1

A fuel cell system includes: a pressure regulating valve that reduces a pressure of a fuel gas; a fuel gas supply passage having a first passage extending between a fuel cell and the pressure regulating valve and a second passage extending from the pressure regulating valve via a cutoff valve to a fuel gas supply source; a pressure sensor that detects a pressure of the fuel gas inside the first passage; and a controller to which the cutoff valve and the pressure sensor are connected. When a pressure value detected by the pressure sensor is an abnormal value, the controller closes the cutoff valve and performs pressure reduction processing for the first passage. Thereafter, the controller judges that the pressure regulating valve has failed when the pressure value detected by the pressure sensor has lowered, whereas the controller judges that the pressure sensor has failed when the pressure value detected by the pressure sensor has not lowered.
