A hydrogen Laptop Battery

Millennium Cell (New Jersey) presented its latest prototype laptop hydrogen battery to Developer Forum from Intel in San Francisco. The system combines the company's patented Hydrogen on Demand technology and a PEM (Proton Exchange Membrane) fuel cell. Sodium borohydride (NaBH4) in solution, stored in a small tank, produces hydrogen and sodium borate (NaBO2) in the presence of water and a catalyst. This hydrogen then passes into the fuel cell where it reacts with oxygen, which generates electricity. The battery, currently external, has a battery life of three hours (compared to three to four hours for current devices), but Millennium Cell has set itself a goal of eight hours.
The company, which has just signed a collaboration agreement with Dow Chimical, is in the development stage and does not have a commercial version for at least two years. She had previously abandoned the development of
hydrogen batteries for passenger cars. It should be noted 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 field of mobile telephony. SJMN 02 / 03 / 05
