Abstract
This application discloses a fuel cell gas monitoring method and system, relating to the field of fuel cells. The method includes acquiring gas state information of the fuel cell through a gas monitoring device and acquiring the actual output power of the fuel cell through a power monitoring module; configuring a normal pressure difference threshold range through a data analysis module and determining whether the actual pressure difference between the anode inlet and outlet calculated from the gas state information exceeds the normal pressure difference threshold range; when the pressure difference exceeds the normal pressure difference threshold range, determining whether the risk is controllable through a safety assessment module; when the risk is uncontrollable, executing safety protection through a safety circuit switch; when the risk is controllable, determining whether the actual output power is lower than the set power; when it is not lower than the set power, reconfiguring the normal pressure difference threshold range; when it is lower than the set power, controlling the operation of the exhaust gas recirculation device or mass flow controller through a life extension control module. This application can avoid frequent start-stop operations and extend the life of the fuel cell.
