Abstract
A system and method for calibrating an offset of a pressure sensor for a fuel cell including one or more fuel cell modules in which power generation is individually controlled by independently supplying hydrogen or air to a fuel cell stack includes a pressure sensor to sense a pressure of the hydrogen supplied to the fuel cell stack, a monitoring unit which monitors whether offset calibration of the pressure sensor of the one or more fuel cell modules is required, a power generation control unit which individually controls the one or more fuel cell modules to continue or stop power generation, and a calibration control unit which calibrates the offset of the pressure sensor of the fuel cell module in a state where power generation is stopped based on a preset offset calibration period or the monitoring of the monitor unit as to whether calibration is required.
