Matsushita Battery Industrial Co., Ltd. has prototyped a fuel cell for use in notebook computers at the CES. For the demonstration a Panasonic Let's note T4 notebook was used. The fuel cell enabled the computer to run about 20 hours continuously by using 200 cc fuel. The prototype is a direct methanol fuel cell that uses methanol (concentration; approximately 100%) as a direct fuel. It is of the so-called active type which uses a pump to supply the fuel electrode with methanol. Methanol with a concentration of approximately 100% is provided from outside the cell and is diluted in the cell before use. The average and maximum outputs are 13 W and 20 W, respectively.
