Development Status of Small PEM Systems at Sanyo

摘要

We have developed a polymer electrolyte fuel cell (PEFC) power generation system that supplies 100-VAC power within two minutes from start-up, and operates at 1 kW for three hours with the hydrogen from two 10-litter vessels. The system, which exhausts only water, is an ideal power generator, with approximately twice the efficiency of an engine-driven generator. A PEFC module operating on a exclusive method of internal humidification was developed for the power source. A newly developed inverter and controller for the fuel cell module was developed to save on the cost.
