“Hydrogen Town Project” is going on in Japan
The project has started on January 15, 2011.
The fuel cell systems using pure hydrogen as their fuel are demonstration tested in a (Kitakyushu) hydrogen town. In the town, ordinary homes, condominiums, commercial and public facilities are installed with different types of fuel cell systems (1 kw, 3 kw and 1,000 kw). Hydrogen gas is produced in Nippon Steel Yawata Works, located near the hydrogen town. Hydrogen gas produced is delivered to the hydrogen town, through the pipelines that are laid in the city area of the hydrogen town. The project is very unique.

Car and Energy Sectors Actually Move toward Early Stage Market of FCVs in Japan
The Japanese FCV industries, including car and energy, take a large step toward the early stage market of FCVs in 2015.
Recently, in Japan, three big automakers and ten energy companies issued a joint statement declaring that the companies make active efforts to build the infrastructure for supplying hydrogen gas to fuel cell vehicles (FCV), which will enter the early market stage in around 2015. About 100 hydrogen stations will be built in the major metropolitan cities of Tokyo, Aichi, Osaka and Fukuoka.
The FCV driving demonstration test using FCV buses has started from the middle of December last year. The FCV buses regularly run on the routes, including the highway, between Haneda airport and two locations in Tokyo. The demonstration test using the hired-car will be conducted before long. The hired-car runs on the highway between Narita airport and the center of Tokyo.
The way for the hydrogen station to obtain hydrogen gas is different between 1) the hydrogen station coupled to the bus route and 2) that coupled to the hired-car route.

Another micro SOFC operating at 450 Celsius degree or lower
A micro-tubular SOFC, co-developed by AIST and Prof. Nigel Sammes, Colorado School of Mines.
It is capable of generating electric power by directly reforming any of various kinds of hydrocarbon fuels into hydrogen fuel even at 450 Celsius degree or lower.
A ceria layer of nanometer-size (reforming catalyst) is formed on the inner wall of the tube.

SOFC and PEFC, their Operating Temperatures Go toward Intermediate Temperatures
In the PEFC and SOFC fields, it seems that much development efforts are directed to the technologies to stably operate those types of the fuel cells at the intermediate temperatures in practical levels.
The fuel cell that Nordic Power Systems uses operates at temperatures higher than 100 Celsius degree, the limit operating temperature of the PEFC.
SiEnergy Systems, LLC (USA) has fabricated a prototype of the micro-SOFC, which operates at 300 Celsius degree.
[Copyright by FuelCell japan]
In connection with this, the lab team led by Prof. Yuichi Shimakawa (Kyoto University) discovered the fact that the oxygen ions anisotropically diffuse in the solid oxide at 300 Celsius degree or lower. The discovery shows that the perovskite-structure oxide exhibits the oxygen ion conductivity in the intermediate temperature region. The discovery is a big discovery when considering the current development trend to operate the fuel cells at the intermediate temperatures. The news on the discovery was released at about this time of the last year. I have carelessly forgotten to refer to the discovery news in my related articles although I wanted to do so. The technical paper describing the discovery was posted to the journal Nature Chemistry and was published on its online version.

Actual EV Market Starts to Move
Following Mitsubishi and SUBARU, NISSAN launched the electric vehicle LEAF into the EV (electric vehicle) market on December 20, 2010.
TOYOTA and Honda will start the sales of EVs in Spring next year.
The actual EV market started to move forward in Japan.
200 km is the running distance of LEAF on a single charge.
And the plug-in charging mode is used for charging the LEAF’s battery.
200 km, this amazed me.
Those specs are enough to satisfy the short-distance transportation requirements.
We have already the technologies on the motor itself and its control, which have sufficiently matured, although its applications, with some exceptions, do not concern the vehicle. I have thought that the decisive problem to be solved is only how to enhance the battery performances.
And, I had guessed that at least a few years were needed until the battery performances reach practical levels.
NEC (partner of NISSAN in the battery field) has a schedule to double the performances of the battery and to half the price of the battery within around two years (says NEC).
My real feeling is that the battery development progresses at higher speed than as expected.
My guess is that the problem left to us is to deploy the charging infrastructure as fast as possible.
EVs are now and will be increasing more than expected.
And the battery manufacturers can't keep up with the demand.
I hope you all have a wonderful holiday season, and to see you again next year.

SiEnergy Systems Successfully Prototypes Micro SOFC
Development is being made to expand the application range of the SOFC (solid oxide fuel cell). The aim of the development is to apply the SOFCs to the power sources of, for example, small electronics devices such as laptops and mobile phones by lowering the operating temperature of the SOFCs, which operate at high temperatures of 700 to 1000°C.
Recently, I wrote three new electrolyte materials for use with the SOFC operating at temperatures from 350 to 600°C.
Meanwhile, at the same time, SiEnergy Systems, LLC（USA）announced the success in prototyping a micro SOFC operating at 500°C or lower, and revealed an innovative process for fabricating the electrolyte film used by the micro SOFC. The fabricating process is capable of scaling up an active area of the electrolyte film to arbitrary dimensions depending on total power needed.
SiEnergy Systems is one of the subsidiaries of Allied Minds (U.S. private equity company).
