摘要： Fuel concentration near a power generator of a DMFC is adjusted by decreasing current taken from the DMFC when the concentration near the power generator of the DMFC is higher than an optimum value and increasing the current taken from the DMFC when the concentration near the power generator of the DMFC is lower than the optimum value. Since the fuel does not come into direct contact with the power generator in the DMFC in a portion from a cartridge to the power generator in the DMFC, drying of the fuel is suppressed. By providing an auxiliary tank capable of storing fuel, concentration of methanol supplied near the power generator of the DMFC is lowered upon activation after long-time storage.
摘要翻译： 当DMFC的功率发生器附近的浓度高于最佳值时，通过减少从DMFC获得的电流来调节DMFC发电机附近的燃料浓度，并且当发电机的发电机附近的浓度增加时，增加从DMFC获取的电流 DMFC低于最佳值。 由于在DMFC中从墨盒到发电机的部分中，燃料不与DMFC中的发电机直接接触，因此能够抑制燃料的干燥。 通过提供能够储存燃料的辅助罐，在长时间储存后激活时，在DMFC发电机附近供应的甲醇浓度降低。
