Abstract: In one aspect, a fuel cell power system is provided. The fuel cell power system includes a ring bus, a plurality of bidirectional uninterruptible power supplies (UPSs), a plurality of direct current (DC) fuel cell modules, and a plurality of bidirectional direct current to alternating current (DC-AC) power converters. Each of the plurality of UPSs is electrically coupled to at least one battery, an AC utility feed, a load, and via a choke, the ring bus. Each of the plurality of DC fuel cell modules includes one or more fuel cells coupled to a hydrogen storage. Each of the plurality of bidirectional DC-AC power converters is electrically coupled to a corresponding one of the plurality of DC fuel cell modules and a corresponding one of the plurality of bidirectional UPSs at the AC utility feed.
