Abstract
Fuel cell has high generation efficiency so that it may replace the conventional power systems. Especially it is expected that the fuel cell is applied to the power source of portable devices such as mobile computer and cellular phone due to its scalability. To promote its applicability, high productivity of hydrogen is required. Thus we started to develop a micro methanol-reformer for hydrogen production. In the methanol decomposition, addition of water is not necessary. A reactor made of Aluminum has 50 mm diameter and 1 mm thickness. The channel before coating catalyst has 500 µm in width, 500 µm in depth and 300 mm in length. Palladium catalyst is formed on the wall of anodized Aluminum channel by impregnating acetone solution of Palladium Chloride. At first, Methanol is fed with a pump, and next, it is evaporated at 80 degree C and reformed at 250, 270, 300, 320 and 350 degree C. The concentration of product is identified by TCD gaschromatographs. In this type of reactor, the optimum temperature for reforming is exist about 320 degree C, and the concentration of hydrogen is about 45% under the methanol feed rate of 1.0ml/h.
