Mitsubishi 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]. 

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.

In mainframes, the acquisition of IBM s Systems 360 and 370 technology was unplanned. In 1970, with the announcement of System 370, Japan s ministry of international trade and industry (MITI) inaugurated a New Series Project, a cooperative undertaking by the Japanese companies to produce a line of comparable computers. Fujitsu and Hitachi were assigned to concentrate on the high end of the IBM product line and NBC and Toshiba on the middle range. The other two, Mitsubishi Electric and Oki, played supporting roles. 

The experimental results referred to here were accomplished in cooperation with Kansai Electric Company Ltd. (KEPCO) and Mitsubishi Heavy Industries Ltd. (MHI), and high pressure combustion tests were conducted at the Central Research Institute of the Electric Power Institute (CRIEPI). Participating members of KEPCO and CRIEPI are gratefully acknowledged. 

In 1997, Sanyo Electric Company discovered that lithium salts such as lithium fluorophosphate (Li2P03F) (173) and lithium difluorophosphate (LiP02F2) (174) can be used as additives in small quantities [162], Furthermore, in 2(X)3, Mitsubishi Chemical Corporation discovered a method for manufacturing lithium difluorophosphate (174) [163],... 

Mitsubishi Electric Corporation (MELCO), Japan, has started to develop large-scale Li-ion batteries for satellite systems since 1998, using large formatted cells. After the first flight in 2003 of an experimental satellite, named Sends-1 , over 100 battery modules have been provided not only to the MELCO standard satellite platform DS2000 series but also to the US companies, middle Asian and European countries, and had been launched successfully in LEO and GEO satellites and space transportation vehicles for the International Space Station (ISS). 

The solar photovoltaic market has been an area of high growth for the past nine years culminating in a 27% increase in 2005 when the world solar cell market was estimated to be worth around five billion dollars. The world s major solar cell producers include BP Solar, Deutsche Cell/SolarWorld, Isofoton, Kyocera, Mitsubishi Electric, Q-Cell, RWE Short, Sanyo, Sharp, Shell Solar and Suntech Power. It is significant that the world s major oil companies are heavily involved in solar power. In a recent statement Norm Taffe, the Executive Vice-President of the Consumer and Computation Division of Suntech Power s Cypress Semiconductor parent company, predicted that solar power could be competitive with mainstream electricity generation in five years time. 

Other companies working on planar solid oxide fuel cell power plants include Dornier as part of the Daimler-Benz group, and, in Japan, Tonen, Sanyo Electric, Murata, and Mitsubishi. 

Between 1966 and 1987 over 1000 patents on reactive extrusion was granted to 200 companies. In order of decreasing number of patents they were Asahi Chem., Bayer, Kabel Metal Gatehoff, BASF, Showa-Electric, Mitsubishi Petrochem., Hitachi Cable, DuPont, Exxon, and many others [Utracki, 1998]. 

A joint development between Mitsubishi Heavy Industries (MHI) and Chubu Electric Power Company is the so called MOLB-Type (Mono-block Layer Built) planar SOFC. The cells are manufactured up to a size of 200 X 200 mm, based on a corrugated electrolyte. In this way the electrolyte also contains the gas channels, which simplifies the design of the interconnects, where plane ceramic plates are used (see Fig. 5). The biggest stack of this type was built of 40 layers, delivering 2.5 kW at 1000°C. 

Mihama-3 is an 826 MW Mitsubishi-built pressurized water reactor (PWR) plant situated in Mihama, Japan, 320 km west of Tokyo. The carbon steel pipe carried the high-temperature steam at high pressure and the pipe was not inspected since the inception of the plant in 1976. In April 2003, Nihon Arm, a maintenance subconttac-tor informed Kansai Electric Power Company, the plant owner, that there could be a problem. Then the power company scheduled an ultrasonic inspection for August 2004. Four days before the scheduled inspection, superheated steam blew the 60-cm wide hole in the pipe. The steam that escaped was not in contact with the nuclear reactor and hence no nuclear contamination has been reported.
