我们提出了一个新的直接甲醇燃料单元，由薄膜电极组装螺旋或折叠。这个燃料单元是由薄膜制成的，是由螺旋状板或锯齿状板上的阳极和阴极电极制成的，由绝缘膜和当前收集器分开。个人的神经元、阴极和薄膜组成单元单元，它们与辅助单元相连。燃料电池是受欢迎的，以实现高输出电压，通过简单的系列连接。因为这是不必要的，以传统双极板的名义连接电极，在制造成本上没有增加，也没有降低可靠性。The fuel feeds for the anode and cathode are achieved through fuel feed material and space on each insulation films， which not require electricity to run a pump or blower.The experimental cells were formed with an active area of 16 cm ^2×2 on membrane folded cells.第117号文件被用作一个附件。Electrochemical catalysts for the anode of the DMFC were produced from platinum and ruthenium，electrochemical catalysts for the cathode of the DMFC were from platinum。过滤文件有十种方法可以插入在anodes之间，以改善他们的甲醇供应。一个三单元DMFC是用提议的zigzag折叠膜电极组装，以获得高输出电压。三个单元组装在膜上有六个电极，以及电极的区域和膜分别为16厘米^2和150厘米^2，对此，请注意。钛网格被用作当前收集器。绝缘膜有切片和3.6 mm的厚度插入了用于喂养空气和用于绝缘干扰细胞的阴极。一个1.7 V的开放电路电压在0.1 mA·cm^\-2\的当前密度大于单个单元格的3次。Moreover，在实验中使用zigzag三个单元，便携式盒式磁带播放器。

We propose a new direct methanol fuel cell by a membrane electrode assembly spiraled or zigzag folded down. This fuel cell is formed by a membrane, which is made up of anode and cathode electrodes on a spiraled sheet or a zigzag-folded sheet, separated by insulation films and current collectors. Individual anodes, cathodes and membranes form a unit cell, which is connected to the adjacent unit cell. The fuel cell is respected to achieve high output voltage through easy in-series connection. Since it is not necessary to connect electrodes, as in the manner of conventional bipolar plates, there is no increase in fabrication cost and no degradation in reliability. The fuel feeds for the anode and cathode are achieved through fuel feed material and space on each insulation films, which do not require electricity to run a pump or blower.The experimental cells were formed with an active area of 16cm^2×2 on membrane folded cells. Nafion117 was used as the membrane. Electrochemical catalysts for the anode of the DMFC were produced from platinum and ruthenium, and electrochemical catalysts for the cathode of the DMFC were made from platinum. Filter papers with ten incisions were inserted between anodes to improve their methanol supply. A three-cell DMFC was constructed using the proposed zigzag-folded membrane electrode assembly in order to obtain high output voltage. The three-cell assembly had six electrodes on the membrane, and the areas of the electrodes and the membrane were 16 cm^2 and 150cm^2, respectively. Titanium mesh was used as the current collector. Insulation films having slits and a thickness of 3.6mm were inserted between cathodes to feed air and to insulate adjacent cells. An open-circuit voltage of 1.7V was obtained at the current density of 0.1mA・cm^<-2>, which is three times larger than that for a single cell. Moreover, in experimental zigzag three-cells, portable cassette player operated.
