Fuji Electric Company

Fuel Cells (UTC Fuel Cells). Worldwide, Fuji Electric Company and Mitsubishi Electric Company in Japan developed PAFC systems for residential and stationary power applications. The PAFC demonstration units have been developed for a wide variety of backup power and even transportation applications. In the 1990s Georgetown University helped operate a PAFC bus fueled by reformed methanol. The original stack was produced with a Fuji Electric fuel cell stack, and a second system was installed with an IFC 100-kWe PAFC stack, shown in Figure 7.15. This bus was operated successfully for a number of years and then sent to the University of Califomia-Davis. However, large relative system size and rapid development of the PEFC have since limited development of the PAFC to stationary power applications [37]. 

Within the last ten years SOEC development has made big progress which can clearly be seen from the tenfold increase in power density. A declining interest in SOEC could be observed towards the end of the last century, when several of the leading companies terminated their activities, amongst them Domier in Germany and Fuji Electric in Japan. Nevertheless a tremendous increase in activities occurred during the last years with... 

In the 1960s, the use of solid-state polymer electrolytes instead of the liquid electrolytes normally used in alkaline electrolysis led to the development of novel concepts for water electrolysis. The US company General Electric was the first to realize solid polymer electrolyte water electrolysis (SPE) with the aid of the solid polymer electrolyte membrane (Nafion ) developed by DuPont [16]. At the same time, ABB [17, 18] in Switzerland and Fuji Electric [19] in Japan also developed PEM electrolyzers with single electrode areas of up to 2500 cm. These...

The Japanese company Ebara Ballard, a subsidiary of the well-known Canadian company Ballard, is the most important maker of PEMFCs. They developed a 1-kW power plant for combined heat and power production. It is remarkable that this unit is designed to be operated for a period of 10 years, in accord with requirements set by the Japanese government. A similar unit also designed for an operating time of 10 years was developed by the Japanese company Fuji Electric. TTiese units cost 12,000 to 16,000 (Adamson, 2006).

The PAFC technology is considered to be the only commercial available fuel cell. The PAFC plants rely heavily on the quality of power produced from the stacks. The largest power of 11 MW has been achieved using the PAFC plant built by international fuel cells and Toshiba for Tokyo Electric Power. The major industrial developers of PAFC are Fuji Electric, Toshiba and Mitsubishi Electric Company (Japan) and UTC fuel cells (ONSI Corporation, United States). Mitsubishi Electric Company has demonstrated cell performance of 0.65 mV at 300 mA/cm. In 1991, Tokyo Electric Company demonstrated cell performance of 0.71 V at 431 mA/cm. Bharat Heavy Electrical Ltd. of India and Caltex Oil Corporation of South Korea are new entrants for the PAFC technology.
