FUEL CELL SYSTEM AND FUEL CELL-POWERED SHIP

摘要

Provided is a technique relating to a fuel cell system in which protection coordination control is executed upon detecting an overcurrent while electric power generated by a fuel cell is being supplied to multiple electrical loads via corresponding breakers, such that performance deterioration of and damage to the fuel cell due to the lack of air can be suppressed while reliably separating from the fuel cell an electrical load experiencing a short-circuit fault and the like. The system is provided with: an air storage unit (20) for storing compressed air; and an air release valve (14) capable of releasing the compressed air stored in the air storage unit (20) to a fuel cell (40) as air for power generation. During the protection coordination control, a control means (60) executes air-release processing for causing the air release valve (14) to open so as to release the compressed air stored in the air storage unit (20) into an air supply path (1).
