    • A low-temperature fuel cell having two porous electrodes is described. An electrolyte having a surface on a fuel gas side and a surface on a reaction gas side is disposed between the electrodes. A method for wetting at least one of the surfaces of the electrolyte in such a fuel cell is also described. To this end the fuel cell is positioned adjacent to at least one channel element containing a semi-permeable membrane through which a fluid guided in the channel element is able to pass towards the electrolyte and at least partly covers at least one of the surfaces of the electrolyte with a layer of water so that the reactions taking place at the electrolyte are enhanced. The invention is advantageous insofar as dosing can be carried out via an adjustment of the pressure or via the concentration of water in the fluid, in particular if the fluid also contains a carrier medium.
    • 描述具有两个多孔电极的低温燃料电池。 在电极之间设置有在燃料气体侧表面和反应气体侧表面的电解质。 还描述了用于润湿这种燃料电池中的电解质的至少一个表面的方法。 为此,燃料电池被定位成与包含半透膜的至少一个通道元件相邻,通道元件中引导的流体能够通过该透液膜朝向电解质通过,并且至少部分地覆盖至少一个表面 具有一层水的电解质,使得在电解质发生的反应增强。 本发明是有利的,只要通过调节压力或通过流体中的水的浓度来进行定量,特别是如果流体还含有载体介质,则是有利的。

    • A catalytic converter for cleaning exhaust gas from an internal combustion engine, in particular a diesel engine or a lean-burn engine, includes at least one honeycomb body coated with catalytically active material and having passages through which the exhaust gas can flow, walls separating the passages from each other, and first and second zones disposed in succession in a flow direction. The first zone has a lower thermal capacity per unit of volume of the honeycomb body than the second zone and the second zone has a thermal capacity of at least 800 joules per liter and Kelvin [J/lK], preferably at least 900. Sheet metal layers in the first zone preferably have an average uncoated thickness of less than 0.06 mm, preferably less than 0.04 mm. Sheet metal layers in the second zone preferably have an average uncoated thickness of more than 0.06 mm, preferably more than 0.08 mm and in particular 0.11 mm. In that way, the first zone can rapidly reach its operating temperature at high exhaust gas temperatures while the second zone stores heat for operating conditions involving a low exhaust gas temperature.
    • 用于清洁来自内燃机,特别是柴油发动机或稀燃燃烧发动机的废气的催化转化器包括至少一个涂有催化活性材料的蜂窝体,并且具有排气可以流过的通道, 彼此之间的通道,以及沿流动方向相继布置的第一和第二区域。 第一区域具有比第二区域更小的蜂窝体单位体积的热容量,第二区域具有至少800焦耳/升的热容量和开尔文[J / lK],优选至少900.钣金 第一区域中的层优选具有小于0.06mm,优选小于0.04mm的平均未涂覆厚度。 第二区域中的钣金层优选具有大于0.06mm,优选大于0.08mm,特别是0.11mm的平均未涂覆厚度。 以这种方式,第一区域可以在高排气温度下快速达到其工作温度,而第二区域将热量存储在涉及低废气温度的操作条件下。
