CPSC DC power supply on the domestic implementation of the recall

CPSC DC power supply on the domestic implementation of the recall

July 2, 2008, the U.S. Consumer Product Safety Commission and RadioShack Corporation today announced a 13.8V DC power supply in the domestic implementation of the voluntary recall.

This recall involves RadioShack 13.8V DC Power Supply catalog number is 22-507 and 22-508, the date code of 08A04 ~ 01A08, figures for the month before the letter, the latter figure for the year. Catalog number and date code marked on the power supply on the back. Surface with a green dot in the power supply and product packaging have been repaired the power supply is not in the recall. The power since October 2004 ~ January 2008 in RadioShack stores nationwide sold, priced at 50 to 85 U.S. dollars / units.

The number of recalled products is about 16 million units. Reason for the recall of the power line connection error, that cause users to be electric shock or fire hazard. Currently, RadioShack Corporation has not received any reports of incidents.

U.S. Consumer Product Safety Commission advised consumers to immediately recalled the power fail, and contact with any of a RadioShack store for free repair.

Japan developed a new catalyst for direct methanol fuel cell

Kyushu Universitys research team developed a direct methanol fuel cell out using a new catalyst, the catalyst can provide the catalyst for Tong Yangs Xingneng existing, except those containing a 50% platinum was reduced.

The ultimate goal of this study is to reduce the concentration of platinum catalyst to the existing content of the 1 / 4, for small direct methanol fuel cells open the door.

The new catalyst is used in direct methanol fuel cell fuel electrode (fuel electrode), the nano-carbon fibers, containing 40% platinum content. Nanometer diameter carbon fiber 7-20nm, also covered with small holes around, this platinum catalyzed reaction to provide a huge surface area.

Household fuel cell information

Live demonstration basically reached the practical level of the domestic fuel cell

Hokkaido Toyako Summit in Japan, METI set of zero emissions house in the conduct of the domestic fuel cell system ENE-FARM demonstration. Ebara Corporation, Matsushita Electric Industrial and ENEOS CELLTECH all a domestic fuel cell system, a working demo. Cell reaction can heat the water heated to 60 ~ 65 â„’, the demonstration is to Foot of water heated to 38 â„’. The electricity generated is used for foot care office lighting, as well as illustrative of the screen.

Domestic fuel cell in 2005 and 2008 validated test, plans to commercialize 09 years. In the final validation tests for 2008, an additional 1120 units will be almost equivalent to the actual products to test the fuel cell system. The display of goods is close to the business of style. For example, Matsushita Electric Industrials products, its service life extended from 3 years to 10 years, power generation efficiency from 35% to 38%.

Price, currently estimated at three million yen or so, remove the 2.2 million yen grant the users burden amounted to about 1 million yen. In 2009 the practical phase, through the implementation of common parts and the platinum catalyst of the use of measures to reduce such costs, the price control to 2 million yen or less. In addition, grants, the current system is perfect, the user must first pay the amount fell to about 700,000 yen. Future goal is to expand the market scale of 1 million units per year, the price fell to around 500,000 yen.
