4.FCV Forefront
(1) Mitsubishi Motors Corp.
Until now the company has made the
development cooperatively with DimlarChrysler Co., but it is changed to an
independent development. The company will not make development of FC per se
which needs vast investment, and it will be concentrated in development of FCV
bodies. Since the company has been making development of electric vehicles
since seventies and its technology can be converted to FCV, the company thinks
that the independent development is possible by applying hitherto accumulated
technology. The company is considering injection of new FCV by its independent
development into the market after fall of 2006, as well as a four-wheel driven
car. [The Yomiuri Shimbun April 18, 2005]
(2) China
In the 10th
program (2001 – 2005) of the 863 project for technological development in
energy field in China, the Chinese government appropriates about 880 million
yuan (about 11.5 billion yen) for FCV development. Subsidiary is also given to
gSuper 2 (Choetsu 2go)h under maintenance. gFCV is now under R and D, but our
target is that we will produce FCV competitive in the price with gasoline
engine cars after 15 yearsh said Prof. Sun (the Vice-Dean of Automobile
Department, Shanghai Tongji University), showing his self-confidence. Prof.
Sun has been independently developing FCV named gSuperh. [The Mainichi Shimbun
April 23, 2005]
(3) Toyota Motors Corp. and General Motors Corp
The
two companies are negotiating establishment of a joint venture to strengthen
cooperation in development of FCV. It will probably be one of agenda in
negotiation between Mr. Cho, the President of Toyota Motors Corp. and Mr.
Wagner, the Chairman of General Motors Corp. It is the policy of the joint
venture to make full range of development from basic components like FC stacks
to trial car manufacturing, and furthermore future cooperative production will
be discussed. However, because it takes long time to widely propagate FCV,
cooperative development has effect on reduction of development cost, but it is
not sure that the cooperation is quick acting for GM in business slump. [The
Yomiuri Shimbun and The Mainichi Shimbun, Masy 11, 2005, The Asahi Shimbun,

(4) Toyota Motors Corp. etc.
Toyota Motors
Corp. and Toyoda Gosei Co. have made development of high pressure tank of
hydrogen compressed up to 35 MPa, and they will install the tank in the new
FCV. In Japan Toyota Motors Corp., Honda R&D Co. Ltd. and Nissan Motor Co.
are making development of FCV independently, but a compressed hydrogen tank up
to 35 MPa used in this country is either a product of a US company, Quantum
Tech. Inc. or a product of a Canadian company, Dynetek Industries Ltd. In the
newly made high-pressure hydrogen tank, resin impregnated filaments are wound
on a base body (filament winding) and resin is lined, so that it is a
container of complex materials. Nylon resin, which has high performance for
preventing hydrogen permeation, is used and carbon fiber is wound on the
outside of the tank. Therefore, the tank thickness can be thin bringing light
weight, and furthermore, reliability and capacity efficiency are improved by
changing mouthpiece structure. The two companies are making development to
produce tanks up to 70 MPa. [The Nikkan Kogyo Shimbun (business and
technology) May 16, 2005, The Yomiuri Shimbun, The Mainichi Shimbun, The Nihon

6.Technological Development of Reforming and
Hydrogen Production
A research group, consisted of Prof.. Domen of Technology Faculty
of Tokyo University, Prof. Inoue of Technology Faculty of Nagaoka University
of Technology and so on, has succeeded in hydrogen production from water by
using wide spectrum range of solar light and visible light responsible
catalyst. The catalyst is solid solution of gallium nitride and zinc oxide,
which is formed by sintering powder mixture of zinc oxide and gallium oxide at
850 under ammonium atmosphere. Photo-catalyst used now is titanium oxide. It
absorbs ultraviolet light of shorter wavelength than visible light and shows
catalytic activity, but it is not active in visible light range. This nitride
catalyst shows catalytic activity in longer wave length range to about 500nm
(absorption edge). Hereafter material of nitride with addition of tantalum
sulfide will be investigated and practical applicability will be found in
several years. [The Chemical Daily May 2, 2005]
7.Technological Development of Hydrogen Storage
US National Institute of Standard and Technology (NIST) has
developed computer-aided design method of carbon nano-tube surface covered
with metal like titanium. Since the metallic decoration has ability of
hydrogen intake, there is possibility to drastically improve performance of
hydrogen storage, if it an be produced in large scale. According to NIST,
hydrogen storage up to 8% in weight ratio could be achieved. [The Nihon Keizai
Shimbun May 16, 2005]
8.Development of DMFC and
Small Size FC
(1) Seiko Instruments Inc.
Sieko Instruments Inc. has
developed micro-PEFC generating electric power by taking hydrogen out of metal
hydride at room temperature. Hydrogen evolution is controlled by pressure
change in FC, so that auxiliary components like a pump and a heater is not
needed. Down sizing is easy, because of high voltage generation. Hydrogen is
formed by reaction of boron sodium hydride with malic acid in catalyst
solution, and when pressure in the hydrogen producer and PEFC cells increases,
a valve is closed to stop hydrogen supply. Reversely, when the pressure
decreases, the valve connecting the hydrogen producer and the catalyst
solution container is opened to automatically supply the catalyst solution to
the hydrogen producer. The dimensions of the trial cells are 125 mm X 50 mm X
30 mm, and the cells can supply electric power of 1 W at 5 V for about 8
hours. Commercialization in 2007 fiscal year is the target. [The Nikkei Sangyo
Shimbun (industries and technology) May 11, 2005]

(2) Bio-venture from Tokyo
University of Agriculture and Technology
A bio-venture, Ultizyme
International Corp., evolved from The Tokyo University of Agriculture and
Technology invented gFC type enzyme sensorh which directly send signal of
sugar concentration. In the sensor, enzyme adhered on an electrode transfers
electrons formed by enzyme reaction to the electrode, and thus it works as the
sensor. The electrode of the sensor could be as small as a needle of needle
therapy. In this sensor a controller for extracting signal in
galvanometer-type sensor is not needed, and the sensor can be downsized. [Fuji
Sankei Business Eye May 19, 2005]

A POSTER COLUMN
Present Status of SOFC Development and Its
Roadmap As to the present performance of stationary SOFC, the electric
efficiency of small size and medium size SOFC is 40% or less and the life is
10,000 hours. Thus it has high efficiency and high performance in comparison
with the other FC, but the production cost is high and it is estimated to be
10 million yen/kW at present. According to the committee on roadmap for
development of FC and hydrogen technology by NEDO, it is aimed that the
electric efficiency would be improved to 42% and the life would be improved to
40,000 hours from 2007 to 2020. The electric efficiency of 45% and the life of
90,000 hours are the target about 2030. The production cost of the SOFC system
is aimed to 250,000 yen/kW assuming 300,000 kW production scale. On the other
hand, as to the large scale SOFC of several MW, evaluation of hybrid systems
will start in 2007, while examination will be made to utilize various fuels
including liquid fuels in addition to gas. A scenario stated that the electric
efficiency would be over 60% and the production cost would be less than
100,000 yen/kW in 2020 – 2030. Thus practical use of the large-scale hybrid
systems would be realized. Elucidating deterioration mechanism and its
preventing method, cost reduction and improvement of performance are important
in SOFC development. The situation is quite the same as in the other FC.
However, technological development for operating large-scale systems and
utilizing multiple fuels are also thought to be important as tasks
characteristic to SOFC.
