A hydrogen Laptop Battery


Share this article with your friends:

Millennium Cell (New Jersey) presented its latest hydrogen battery prototype laptop at Intel Developer Forum in San Francisco. The system combines the technology patented Hydrogen on Demand by the company and a PEM fuel cell (Proton Exchange Membrane). Sodium borohydride (NaBH4) solution, stored in a small tank, produces hydrogen and sodium borate (NaBO2) in the presence of water and a catalyst. This hydrogen is then passed through the fuel cell where it reacts with oxygen, which generates electricity. The battery, for external time, has a range of three hours (against three to four hours for current devices), but Millennium Cell has set a target of eight hours.
The company, which has signed a collaborative agreement with Dow Chimical, is in the development stage and does not provide marketable version for at least two years. She had previously abandoned the development of
hydrogen batteries for cars. Note that many other companies are working on fuel cell projects for various portable devices, such as Toshiba or NEC, also in the field of computers, or NTT in the mobile telephony. SJMN 02 / 03 / 05
