摘要： A scavenging process is performed on the anode side by opening an air supply valve to remove liquid droplets in a fuel gas flow field using the compressed air from an air compressor. During the scavenging process, when a start up signal from an ignition switch is received, the start up of a fuel cell is prohibited until the gas in the fuel gas flow field is replaced completely by air.

摘要： A fuel-cell system 1 includes: a fuel cell 13 configured to generate electricity through reaction between hydrogen gas and air; a compressor 12 configured to supply air as a scavenging gas to a reactant gas path 13a of the fuel cell 13; a control part 18 configured to control an amount of air supplied from the compressor 12 to the fuel cell 13 to perform scavenging of the fuel cell 13; and pressure sensors P1 and P2 configured to monitor a pressure drop in the reactant gas path 13a of the fuel cell 13.
