The company has a plan to incorporate the new fuel processor into a next generation ENEFARM (residential fuel cell cogenerator).
The new fuel processor is about 2/3 in volume, and almost halved in manufacturing cost when compared with the previous fuel processor).
Those advantages result from significant simplification of the fuel processor structure and use of the new catalyst.
Significant Simplification of Processor Structure
The structure of the previous fuel processor is complicated to improve the reforming efficiency. To cope with this, the company reduces the number of necessary parts to 1/3, and the total welding line length by 40% (when compared with those of the previous one). The reforming efficiency of the new fuel processor is equal to that of the previous one.
Developed High Performance Catalyst
As known, the fuel processor uses a catalyst for promoting the reforming reaction.
To secure required performances, the old fuel processor needs much catalyst.
This results in the large volume of the fuel processor.
Where the new catalyst developed this time was used, the amount of catalyst required for the reforming was reduced by 30% to 50%. This results in considerable reduction of the processor volume and size, and the manufacturing cost.
Tokyo Gas’s Fuel Processor
Tokyo Gas has developed the fuel processor as well as the fuel cell.
October, 2000 – developed a 1-kW fuel processor of 83% (HHV)
November, 2003 – processor structure was redesigned, the reforming efficiency was improved in low output condition, and the weight was halved.
The company has licensed the result of developed technologies to Ebara-Ballard.
An excellent environmentality of the fuel processor was proved in the large-scale demonstration test project of residential fuel cell cogenerators (started from 2005).
The fuel processor technologies developed this time will be licensed to Ebara-Ballard and others.
The next-generation ENEFARM by Tokyo Gas will be launched in the first half of 2010. The new ENEFARM will be featured by size reduction and reduced price.

Curricular Changes in Teacher Education
Â
Â
India is a developing country. We have thousand years of Tradition and Culture. Different types of people are living in India. In olden days the educational institutions were called as âAshramamâ and teacher was called as âGuruâ. Guru is a respectable person in the society after mother and father. According to our Vedas Guru is a third God. In olden days they were given importance for shravana, Dhyana and Asana. All types of information are there in Vedas. Yoga is a greatest gift of India to the world. Yoga has its origin in the Vedas, texts that were heard by ancient sages in their state of meditation, and hence are known as srutis. The great sage Vyasa organized the Vedas in a systematic manner. Hence he is known as Veda Vyasa.
Now we are living in the technological world. Vast changes are occurring in day to day life of human being. The effect of Television, Telephone, Radio, Computer, Internet and Mobile is very much in our daily life. Even today also teacher is a role model for the students in the society. Teaching profession is a respectable job in the society. But there are enormous changes… Continue reading
Story telling is one of the oldest art forms that have ever come into existence. In the past, tribes used to gather around and tell stories about their gods, their history, and their legends. This was how so many things were taught and passed down from the elders to the younger generation. This is also a great thing to use or incorporate into an elearning tools generated module. This is important with elearning because a lot of elearning modules tend to just relay information in a colorful but not exactly meaningful way.So what is it in the story that makes it such an effective teaching tool? Well, a story not only gives flavor to the lesson, it gives it life. It gives structure to the learner’s experience of the lesson. What are its implications? How would real people probably react when faced with its issues? Why does it matter to anyone? And more abstractly, how does it feel, taste, look like, smell, and or sound like?This does not mean that one has to use a story in every lesson. But one must think in terms of a story. Getting the flow of a lesson module can sometimes be just… Continue reading
