    摘要： The present invention relates to a direct methanol fuel cell having reduced methanol crossover, which comprises a layer of material for controlling the diffusion rate of fuel. More particularly, it relates to a direct methanol fuel cell in which the material for controlling the diffusion rate of fuel is interposed between an anode and a fuel reservoir or positioned within the fuel reservoir, and thus, the diffusion rate of methanol is reduced even when using high concentration methanol fuel, such that the injected methanol is completely reacted in a catalyst layer so as to fundamentally reduce unreacted methanol, thereby suppressing the methanol crossover phenomenon and exhibiting high power density. In the inventive direct methanol fuel cell, the diffusion rate of fuel is controlled using the fuel diffusion rate-controlling material so as to suppress the methanol crossover phenomenon, thereby increasing energy density and output density. Also, since a high methanol concentration of aqueous methanol fuel is used in the inventive fuel cell, the fuel cell can be used for a long period of time even with a small amount of fuel, and the volume of the fuel reservoir can be reduced, thus making it easy to miniaturize the fuel cell. According to the invention, the performance of all kinds of direct methanol fuel cells can be improved and the fuel cells can be used as electric power sources for small-sized portable electronic products, such as portable phones, PDAs, and notebook computers.

    摘要翻译： 本发明涉及具有降低的甲醇交叉的直接甲醇燃料电池，其包括用于控制燃料扩散速率的材料层。 更具体地说，本发明涉及一种直接甲醇燃料电池，其中用于控制燃料扩散速率的材料介于阳极和燃料容器之间或者位于燃料储存器内，因此即使当甲醇燃料电池的扩散速率 使用高浓度甲醇燃料，使得注入的甲醇在催化剂层中完全反应，从根本上减少未反应的甲醇，从而抑制甲醇交叉现象并表现出高的功率密度。 在本发明的直接甲醇燃料电池中，使用燃料扩散速率控制材料控制燃料的扩散速率，以抑制甲醇交叉现象，从而增加能量密度和输出密度。 此外，由于在本发明的燃料电池中使用高甲醇浓度的甲醇水溶液，所以即使使用少量的燃料也能够长时间使用燃料电池，并且可以减少燃料容积的体积， 从而容易使燃料电池小型化。 根据本发明，可以提高各种直接甲醇燃料电池的性能，并且燃料电池可以用作便携式电话，PDA和笔记本电脑等小型便携式电子产品的电力来源。

    摘要： The present invention provides a thermoplastic lignin polycondensate. The thermoplastic lignin polycondensate produces no fumes and odor even at a normal melt processing temperature. The melt viscosity of the thermoplastic lignin polycondensate can be measured even when heated to 200° C. or more. The thermoplastic lignin polycondensate can be prepared by selectively activating the hydroxyl reactive groups of lignin to suppress the crosslinking reaction of the hydroxyl reactive groups, which allows a linear or grafted linear growth of the lignin polycondensate.
