Online calibration method and device for fuel cell power generation system and corresponding equipment

The invention discloses an online calibration method and device for a fuel cell power generation system and corresponding equipment, and the method comprises the steps: setting a temperature interval and a current interval, and obtaining m water temperature discrete values and n current discrete values in a working range of a fuel cell; when the fuel cell power generation system is in an idling state, the electronic load is in a current control mode; after the fuel cell power generation system enters a stable state, the temperature control equipment is started and reaches a preset water temperature value; sending the initial value of the calibration parameter to the fuel cell power generation system; obtaining observation index values of the fuel cell power generation system when the fuel cell power generation system operates at different water temperature discrete values and different current discrete values; the observation index values under each water temperature discrete value and each current discrete v
