Hydrogen sensor

Technology transfer of "Hydrogen sensor" invented by Niigata University and our technology developmen

We have found out a new type hydrogen sensor at a research presentation organized by the university. It was just quite a find. Our team did well in the technology transfer by showing a prototype device. This achievement brought us a Japan's MEXT Award in 2006. In addition, it was elected as "the 100 top examples of technology transfer from around the world" in the Association of University Technology Managers (AUTM) in 2007.

The hydrogen sensor has been invented at a materials laboratory as useful application on an original experimental method. It was patented as "an EMF type quick hydrogen sensor". The most distinctive feature is the quick responsiveness and high sensitivity in a low hydrogen gas concentration region with a great gas selectivity. An intensive property of electromotive force (EMF) can make into a miniaturization form. The inherent EMF value of the sensor can give high reliability for the hydrogen gas detector.

By market research of technology with the inventor, various hydrogen sensors for different purposes have been developed as is shown in the figure. Recently, we have found a hydrogen gas sensor for all concentration regions. And, we will go further technology development for hydrogen energy society.

Sensing behavior of "EMF type quick hydrogen sensor"

We can see its quick responsiveness.

It answers to the remnants hydrogen gas in a straw.

A sensing operation of the incorporation with a wireless device

It sends the device's ID and hydrogen concentration every one second.

The working time of the device is about ninety days.

A demonstration of fuel cell assisted minicar

It was jointly developed by Niigata University.

In the back bed, there are fuel cells and hydrogen storage alloy tank with fuel indicator.
