Hitachi Wansheng successfully developed new generation aluminum water and fuel cell system

Hitachi Wansheng has developed a new type of fuel cell system (Figure 1), only adding water to generate hydrogen in aluminum, and the use of hydrogen as a fuel for power generation. The utility model is characterized in that the hydrogen can be generated at room temperature by using cheap aluminum and hydrogen, and no catalyst is needed in the production of hydrogen. It can also reuse the waste materials and other aluminum alloy, so as to realize the effective utilization of the resources. Envisaged for the first time there is no power supply to the surrounding mobile phone base stations, such as the use of emergency power supply, and military applications, the future will be about 10W to 100W power of small and medium equipment development. The use of Al3H2O, Al (OH) 33/2H2 this reaction to produce hydrogen. 1.3L can be produced by using 1g aluminum and 2G by reacting the particles and the particles that do not condense, which is treated by special treatment of aluminum and water. Study on the reaction of hydrogen and aluminum water use, was originally Watanabe Masao professor in Muroran University of japan. See the University's display at an exhibition on 2004, Hitachi Wansheng also began the study. At that time, only about 60% of the hydrogen production theory, but also in the low cost of aluminum powder production methods, there are some issues. Hitachi Wansheng has since done practical development is to establish a production technology, is to reach two per g aluminum can generate 1.3L hydrogen, namely the theoretical value of 95% levels. At this conference, the use of a trial production of fuel cell systems, the actual notebook driver demonstration (Figure 2). The sample consists of a hydrogen generator, a power generating unit, a lithium ion rechargeable battery and a control circuit (Figure 3). The overall size is 160mm * 100mm * 60MM, weight 920g. The average power is 10W, the maximum can reach 20W. Voltage of 7.4V. Fluorine solid polymer electrolyte membrane was used in power generation unit. The hydrogen generating device is respectively provided with a water tank with a capacity of 50mL and a powder box. As long as the water is sent to the aluminum powder box by a small pump, hydrogen is generated in the aluminum powder box. It is reported that the use of 20g aluminum can drive the laptop 4 ~ 5 hours, the required water is about 40mL. In the future, it is expected to achieve the same flux density as the lithium ion rechargeable battery. Japan's Wan Sheng believes that in the future through the development of key technologies, the current size of 160mm * 100mm * 60MM can be reduced to 97mm * 87mm * 31mm. If this can be achieved, it will be able to increase the unit volume flux density to the lithium-ion rechargeable battery 300Wh/L (Figure 4). In addition, as the development of the fuel cell using MEA (membrane electrode), Hitachi Wansheng through the electrode structure optimization, 280mW/cm2 realized the power density. The company is not only ready to carry out fuel cell systems business, but also ready to vigorously develop MEA's export business.
