Japan's leading semiconductor manufacturer Rom (headquartered in Kyoto, Japan) and Aquafairy (headquartered in Kyoto, Japan) and Kyoto University have jointly developed a small, lightweight, high-power hydrogen fuel cell that can be used for portable power sources such as smartphones. The product is currently under development). This hydrogen fuel cell overcomes the weaknesses of dry batteries, lithium ion batteries, and fuel cells using methanol, while achieving significant weight reduction, high power, and safety. Significantly improved the convenience of the power supply in places where AC power cannot be used.
Since fuel cells are more efficient and smaller and lighter than conventional batteries and rechargeable batteries, the future spread and market expansion are expected. Although fuel cells using methanol and hydrogen have begun to spread, methanol fuel cells are difficult to achieve high power. Although hydrogen fuel cells can achieve high power, they are difficult to miniaturize and difficult to handle due to the use of steel cylinders. Therefore, the popularity is difficult.
This time, Roma and Aquafairy used the original technology to successfully cure calcium hydride into a sheet, which can produce a sheet of less than 3 cc (38 x 38 x 2 mm3) and water to produce about 4.5? of hydrogen, 5 Whr. electricity. This hydrogen fuel cell is small and can work at room temperature. It can be used not only for the charging of smartphones , but also as a battery for tablets and PCs, as a power source for outdoor and remote areas, and as a backup power source for disasters. In terms of environmental protection, carbon dioxide and harmful gases are not emitted at all due to the use of water and calcium-based fuels. It can be disposed of as general waste when discarded. It is extremely environmentally friendly compared to previous batteries. Battery.
This technology is realized by combining the power circuit technology, application development technology and high-tech development of hydrogen fuel cell owned by ROHM . The Kyoto University Advanced Electronic Seminar was held in Kyoto University in the fall of 2010 to promote cooperation between industry, universities and research institutes. The meeting (AES) was an opportunity to start interoperability with Kyoto University and has this development.
ROHM, Aquafairy and Kyoto University will actively promote reliability evaluation and further improvement, and strive to enter the practical stage in 2013. In addition, the hydrogen fuel cell will be unveiled at the Roma booth at CEATEC JAPAN (October 2012, Chiba, Japan) and Electronica (November 2012, Munich, Germany).
In addition, Roma and Aquafairy will continue to improve the lineup of original products such as smartphone charging, and at the same time, we are working with Kinki Systems to develop fuel cells for seismometers used in remote areas where power cannot be ensured. This product uses the sheet-type fuel cell developed this time. Compared with the conventional lead-acid battery, the weight is only 1/4, and the weight is successfully achieved. Only 3 kg has a large capacity of 400 Whr. This product is scheduled to be released in April 2013.
In the future, ROHM will continue to promote the development of fuel cells suitable for various applications by integrating circuit design technology, application technology and Aquafairy's fuel cell technology. In addition, the development has been strongly supported by Professor Hirao of Kyoto University, and future research will be conducted on the next generation of hydrogen generators and resource utilization systems.
1) Small and lightweight
2) A large-capacity, high-power battery with a battery capacity of 5Whr can be fully charged in about 2 hours.
3) Environmental protection
The hydrogen fuel cell developed this time uses a solid that generates hydrogen by adding water, and can be used for power generation by synthesis of water. Therefore, the product generated during power generation is only water (water vapor), and carbon dioxide and harmful substances are not generated (volatile Organic compounds: VOC). It can also be disposed of as general waste when it is discarded. It is an extremely environmentally friendly fuel cell.
4) Can be stored for 20 years
Since the dry battery and the lithium ion battery always have a potential difference, the battery can be discharged even if it is not used, and the available power is gradually reduced, so the storage period is 3 to 5 years. The hydrogen fuel cell developed this time prevents the fuel from deteriorating through the aluminum laminate, and has no energy waste, and can be stored for more than 20 years. The power can also be changed if necessary.
