(1) Showa Denko K. K.
Showa Denko K. K. has developed a PEFC separator using complex material of carbon and resin. The weight of the separator is one fourth of the metal separator, and the conductivity is about 10 times higher than conventional graphite. The materials of this complex are fine powder of graphite and resin such as polypropylene, polybutadiene etc at the ratio of 7 to 3, and they succeeded in increase of the conductivity by adding small amount of boron. The higher the ratio of resin, the easer it is handled but with sacrifice of the conductivity. It is concluded that the above volume ratio is the optimum for making full use of the materials characteristics at their maxima. For manufacturing, the mixture is extruded into sheets with an extruder and then channels for fuel gas and air are formed by press molding. The future tasks are thickness and cost reduction. The thickness is 1.5 mm, and the production cost is high and about several thousand yen per one sheet at the present. (The Nikkei Sangyo Shimbun (industries and technology) May 23, 2005.)

(The Nikkei Sangyo Shimbun (industries and technology) May 31, 2005.)

(3) Seiko Instruments Inc. (SII)
Seiko Instruments Inc. finished development of a new small size PEFC of large output and high efficiency, in which metal hydride, i.e., sodium borohydride is used as fuel. The size of this micro-FC is 125 mm X 50 mm X 30 mm and the voltage is 5 V. The company aims at real use in digital cameras, DVD etc as power devices. In this system stable reaction proceeds by hydrogen gas control mechanism, though it is passive type. When the pressure decreases by discharge, catalytic solution is flowed into the fuel container by the pressure difference, and the reaction proceeds at the room temperature to form hydrogen. When hydrogen gas fulfills the container, flow of the catalytic solution is stopped because of the low-pressure difference. The metal hydride of sodium borohydride as the fuel does not emit CO2 when producing hydrogen, and it does not degrade catalyst performance as in DMFC. For the present they are aiming at a system of 1 W as a power source of mobile phones, and in the future they have plan to increase the output to about 3W to cope with demand of digital cameras. (The Denki Shimbun (electricity) June 7, 2005.)

This is useful to develop some device to prevent the water freezing in cold climate. By using this software, FC development can be made efficiently by reducing trial assembly of the stacks. Prof. Okano is expecting development of simulation software for FC systems as a whole till 2007 by collaboration with Victoria University. (The Nikkan Kogyo Simbun (business and technology) and The Shizuoka Shimbun May 26, 2005, and The Nikkei Sangyo Shimbun (industries and technology) May 27, 2005.)

(3) Takasago Ltd.
Takasago Works developed an apparatus gMIU seriesh for multi-channel impedance measurement, and it is developed for battery related fields such as FC and lithium battery. To measure internal resistance within a cell, impedance measurements should be done by changing the frequency, but conventional apparatuses are mainly made for measurement of a single cell and they are inconvenient for measurement of multiple cells connected in series. With this new product, AC impedance measurement is done in the frequency range from 10 mHz to 5 kHz. At the maximum, 41 channels can be measured with a single apparatus and 640 cells can be measured simultaneously by cascade connection using 16 sets. The data acquisition of high rate and large capacity can be done quickly with PC using LAN, and the data can be displayed graphically in Cole-Cole plots.
