@On April 1, 2005 MCFC Consortium set forth success in electric generation test of its MCFC plant of 180 kW output under 12 atmospheric pressures. It is possible to design a compact system by high pressure operation and to increase plant output efficiency.
@The test results show that the FC output efficiency is 43% and it is by 3 – 4 points lower than efficiency of usual MCFC, but it was stated that the efficiencies could be increased by future improvement, such as reduction in internal resistance. In conventional MCFC reforming efficiency of methane etc was decreased by about 20 % in high-pressure operation, but this problem was overcome by additional reforming process using exhausted heat evolved in electric generation. Furthermore, gas leakage from cell stacks was perfectly prevented, and loss of electrode catalyst could be reduced by adjusting concentration of carbon dioxide. Reliability of the system was increased as a whole, and about 500 hour operation was achieved. If a combined cycle were made with advanced gas turbine for example, net electrical efficiency of 50% could be achieved. At the same time, about 5,000 hour operation and 41% net electrical efficiency can be attained for a small scale system of 150 kW under 3 atmospheric pressures.

5.Trends in SOFC Development
(1) Daiichi Kigenso Kagaku Kogyo Co.
@Daiichi Kigenso Kagaku Kogyo Co. is examining commercial production of scandia-stabilized zirconia (ScSZ), which was developed by collaboration with Toho Gas Co. for SOFC electrolyte material. The electric conductivity of ScSZ is two fold higher than that of YSZ, and thus it enables large increase in the efficiency together with scale down of SOFC. It has been shipped to many firms and research institutes as a sample. Because it was demonstrated that scale down and cost reduction could be realized by using this material, Toho Gas Co. decided to commercialize SOFC generating plant by using this material. In relation with this decision, installation of mass production line is now being examined and real industrialization is expected. In this collaboration between these two, tasks for making products of practical use, such as endurance, were completed and stabilized performance under any condition could be achieved.
@Daiichi Kigenso Kagaku Kogyo Co. installed a pilot plant in the Osaka factory and established facility for medium scale production. As to conventionally used YSZ, the company are already making it in mass production scale, and some firms in Japan and oversea countries preliminarily decided to use it. To industrialize both products in full scale, further large cost reduction is essential, and establishment of new technologies to achieve this task are keenly needed. Firms other than Toho Gas Co. tentatively decided to apply this new material in their FC, and hence there is some possibility for this material to grown up to a product of large scale use. (Daily Chemical Industries Newspaper, March 23, 2005)

(2) Hitachi Maxell. @Hitachi Maxell. published on March 29, 2005 that it has developed technology for making highly dispersed PtRuP catalyst (2 nm grain size) by adding non-metallic phosphorous into platinum – ruthenium alloy using metal plating technique. It was used in DMFC and the maximum output density is increased by 1.7 folds (64 mW/cm2) in comparison with conventional catalyst. By the conventional method in which fine catalyst particles are bore on large surface high-conductivity carbon, the catalyst particles are buried into fine pores of carbon and they does not contribute to reaction of methanol etc. In newly developed PtRuP catalyst metallic bonds in Pt and Ru are dissociated by adding phosphorous having large inter-atomic interaction with Pt and Ru, so that the catalyst particles are kept fine irrespective of carbon surface. The distribution of particle size is narrow, i.e., 1.5 – 2.5 nm. Based on this new technology the company is considering research and development oriented to PEFC, DMFC etc. (Chemical Industries Newspaper, March 30, 2005 and Nikkei Business Newspaper, March 31, 2005)

(3) Showa Denko K.K.
@On April 5, 2005 Showa Denko K.K.., set forth development of a carbon-resin molded separator for PEFC. This new separator is promising in conductivity and endurance compared with conventional separator of graphite carbon. Moreover, the new one is less brittle and it can be produced in low cost. It is more durable and light even than metallic separators. The new product is made by using newly developed graphite fine powder, whose size distribution and particle shape are optimized, and the conductivity is 10 fold higher than conventional graphite. The binder resin for complex formation can be either thermoplastic resin or thermosetting resin, but the complex has high conductivity and high mechanical strength with toughness for either resin. Speedy molding method of about 15 s. per one separator was also developed, so that it could hopefully be produced at about 1/10 cost in future when it is widely used. The other characteristics are low weight (1/3 – 1/4 compared with the metallic separator) and thin thickness of 200 – 300 micron m, which cannot be achieved for conventional graphite separators. Proceeding in evaluation by PEFC makers, further research will be made for further improvement.

9.Development of Hydrogen Storage and Transportation
@On March 24, 2005 the Agency of Industrial Science and Technology and Japan Metals & Chemicals Co. published a new fusion method to produce hydrogen absorbing alloy of finely controlled composition. Instead of inert gas of argon hitherto used in a fusion furnace, gas mixed with helium is used to reduce vaporization of light metal, e.g., magnesium and hence it is possible to obtain alloys of aimed composition. The target is development of alloys to absorb hydrogen of over 5 wt% and to release it for application to FCV etc. For hydrogen absorption alloys containing light metal, such as magnesium, calcium, lithium etc., as main components are now being investigated, but one of the problems is vaporization of these metals because of their low melting and vaporizing temperatures. It is especially the case when high melting metals, e.g., nickel, are melted with these light metals. Furthermore, due to smoke of fine particles formed through the vapor, visual observation of molten state becomes hard. By investigation of inert gases, the agency and the company found that this problem can be solved by using gas mixed with helium. They confirmed that the aimed composition can be obtained in application of systems whose main components are calcium and magnesium, and also improvement in yield was also confirmed. Hereafter they will make development of high capacity alloys and also make investigation and analysis on the effect of helium containing gas.

The production of solar cells in 2004 fiscal year is 360MW including home-use and industrial use, and turnover is 110 billion yen. Those in 2005 fiscal year are expected to be 400MW and 150billion yen, respectively, and 70 billion yen is assumed for industrial use. By strengthen demand creation in overseas, it is planned to expand to 500 billion yen in 2010 fiscal year. By enlargement of the market some are anxious on price up due to lack of materials, but the company stated that their new product of crystalline thin film solar cells modules uses a little materials (silicon) and production cost can be kept low. Furthermore by increase in ratio of thin film cells and their mass production, even cost reduction is anticipated. (Electromagnetic Wave Newspaper April 1, 2005)

Development of Materials for Effective CCS (Carbon Capture and Storage)
At the R and D center of Toshiba Corp., development of epoch-making materials for CO2 absorption is now in progress. It is compound of lithium and silicon, i.e., lithium silicate, and the company first studies compound of lithium and zirconium, namely lithium zirconate, but since zirconium is rare metal so that it is not suitable for mass production. Searching for substituting other materials, this lithium silicate was found. Lithium silicate absorbs carbon dioxide below 700 and releases it over 700. Using this property the material can be used repeatedly. In comparison with conventional organic amine compound as absorbing liquid, operating energy and space for equipment could be reduced.
