摘要
NTT has developed a portable fuel cell system (PFCS) for telecommunications systems. The PFCS consists of a small fuel cell, a hydrogen cylinder, a 55 V DC-DC converter and a carrier. The PFCS supplies 250 W of DC power for 5 hours using the 10.5 l hydrogen cylinder. The system can be moved easily by using the carrier. The DC-DC converter can allocate the current equally to each PFCS, and the parallel connections between the PFCSs increase the power that can be generated for telecommunications equipment. Simultaneous operation of three PFCSs provides enough power to operate a telecommunications system in a building. The operation remains stable whether commercial power is discontinued intentionally or unintentionally. The PFCS generates power quietly and cleanly, and proved to be used as an indoor emergency power source for telecommunications systems.
