FUEL CELL : READY TO MOVE NOTEBOOK BATTERY LITHIUM ?
Since a few years ago, the vendors have found a replacement battery Lithium-ion (Li-ion) and Lithium-polymer (Li-Po), which until now is still the driving force mainstay in notebooks and most other electronic gadgets. His name is the fuel cell.
Compared to other devices in the computer fixed, battery is one whose development is very slow. So leletnya, product innovation is practically a road in places, very different from the hard disk or flash drive with a new-generation often appeared.
Is the battery technology is too difficult that inhibited innovation? Not really. You need to know, the vendors have found a fair amount of time the fuel cell is known as a battery replacement technology.
More Autos
Let's go back to the year 2002. At that time, vendors such as Casio Computer, Toshiba, Hitachi, Motorola, and MTI has introduced a fuel cell made from methanol as the primary candidate replacement Lithium. The ideal addition to use in mobile products such as laptops and mobile phones, the fuel cell is also considered efficient, power consumption can increase the time gadget to 10 times longer.
In September 2005, Sony Ericsson is very optimistic with homemade portable fuel cell to issue a statement that they are going to be the first company to comercializing battery for notebooks. The prototype fuel cell made by LG weighs under 1kg and allegedly capable of producing up to 25Watt power, or more than 10 hours of wear time. At that time, Motorola memrediksi global market for fuel cells could reach 600 billion USD in the year 2006, and will continue to rise to 1.9 billion USD in 2010. However, until the year 2006, the fuel cell has not been commercial.
Around March 2006, Taiwanese vendors named Antig stated battery fuel cell-based notebook besutan they will be in computer stores in early 2007. At first, choosing Antig early January 2007 as the right time to start selling their products because of regulatory agency International Civil Aviation Organization (ICAO), which specifically forbids the previous passengers carrying liquids such as methanol in the aircraft, plans to remove the rule in January 2007. In fact, the rule was also revoked, it even tighter.
2-3 Year Commercial Again
Entering the mid-year 2007, the fuel cell is also not ready to be thrown into the market. Latest news on developments came on August 13th, 2007. Samsung has perfected the technology Direct Methanol Fuel Cell (DMFC) that could belong to a public display at the end of December 2006. Its size is reduced to dimensions 150mm x 50mm x 50mm. Total energy capacity of about 1200W with 20W energy output.
The principal advantage of the DMFC is its ability to operate the ultra-portable notebook series Q30, Q35, and Q40 Samsung besutan to eight hours a day for a month. Reportedly, South Korean vendors are going to release its findings later this year at 2008. Even so, analysts predict the fastest 2-3 years of new fuel cell could really commercial.
You may be exasperated with the process of adaptation leletnya IT industry from Lithium batteries to fuel cells. But this is about when conditions began to shift the position of Lithium Nickel batteries (NiMH and Ni-Cd2). Although it was clear that the performance of Lithium proved far better than the Nickel, it still took a long time for the vendors to adapt it into their products.
The process of adaptation, especially to replace something that is mass has been used in most electronic products in the long run (eg Lithium batteries that have been used for almost 16 years), it is not easy. In addition to elevated raw material prices are still expensive, need intensive education to consumers who still lay with the fuel cell technology because they have to get used to no longer noticeable to the electrical gadgets, but recharge a spare battery with methanol.
A little about the Fuel Cell
Fuel cell was first invented by Sir William Grove in 1839. Grove discovered that water can be broken down into hydrogen and oxygen when given an electric current. This process is then called electrolysis. He then hypothesized that if the process is reversed to produce electricity and water. Fifty years later, Ludwig Mond and Charles Langer popularized the term "fuel cell" when he was making a practical model to produce electricity.
Fuel cell is essentially an electrochemical energy conversion devices. He was able to convert compounds of hydrogen and oxygen into water, and in the process of generating electricity. Unlike the battery that changed all the chemical compounds in the body into electricity and then run out and should be discarded or must be refilled using the ration, chemical compounds in the fuel cell continues to flow in the cell is constantly that it never dies.
There are many types of fuel cell batteries, but most vendors selected as replacement candidates Lithium batteries are DMFC (Direct-methanol FC). DMFC actually been developed since the early 90's. The principle is roughly this: a solution of methanol is added to the side of the battery anode (fuel side) and will break down into protons and electrons and carbon dioxide. Electrons will be taken out of the fuel cell in the form of electrical current which is then used to run a notebook for about 8 hours. These currents then flowing back into the fuel cell cathode (air side). Well, protons and electrons at the cathode and reacts with air to form water, which then removed from the system. |
