摘要： An electrode-electrolyte unit for a fuel cell which prevents the permeation of the fuel used or the permeation of water through the electrolyte layer. An electrolyte is subdivided into two electrolyte layers with a barrier layer disposed between them. The barrier layer is permeable only to protons and may be coated with a catalytically active porous layer having a high effective surface area. A porous layer on the side of the unit facing the cathode increases the electrochemically active surface area and a porous layer on the side of the unit facing the anode ensures that a sufficient amount of hydrogen is dissolved. The fuel used can be hydrogen or methanol and suitable electrolytes include membranes or other solid or liquid electrolytes.

摘要： The invention relates to a fuel cell stack in which, according to the invention, several elements of the fuel cell stack are advantageously sealed by a seal in order to form a continuous operating material channel. The inventive fuel cell stack can be provided with a very compact design, whereby the layer thickness of an individual fuel cell is, on a regular basis, distinctly less than 1.5 mm and, advantageously, even less than 1.2 mm.

摘要： The invention relates to a device for cleaning waste gases for a direct alcohol fuel cell or for a direct alcohol fuel cell stack, comprising at least one supply line for supplying an oxidizing agent into a cathode space of a fuel cell and at least one evacuation line for evacuating waste gas out of a fuel cell. The supply line and evacuation line are arranged next to one another at least in one area and are separated by a porous layer. A catalytic converter is placed on the surface of the porous layer oriented toward the evacuation line. In the inventive waste gas cleaning device, the advantages of an internal utilization of heat and of an at least partial water circuit with an effective catalytic conversion and reduction of removed non-converted alcohol, particularly methanol, locally unite at one location of the fuel cell system. The waste gas cleaning device simultaneously serves to preheat and wet the supplied oxidizing agent and can be advantageously provided with a very compact design.

摘要： In low-temperature fuel cells according to prior art, the problem often arises that the diffusion layer of the cathode is filled by water which is permeated or produced on the cathode, such that oxygen can no longer be transported to the catalyst layer of the cathode in a frictionless manner. As a result, said fuel cells are regularly used with a high excess of oxygen in order to reduce the cited transport problems for the oxygen. The inventive fuel cell enables said problem to be solved in that the arrangement of the diffusion layer and the catalyst layer of the cathode is inverted. The diffusion layer, which is embodied in such a way as to also conduct ions, is directly adjacent to the electrolyte membrane. The catalyst layer oriented towards the free cathode space can advantageously directly react with the supplied oxygen without further transport problems. A further advantage lies in the fact that the water produced on the catalyst layer of the cathode and/or permeated by the electrolyte membrane and the diffusion layer can be easily withdrawn via the free cathode space.

摘要： In a direct-methanol fuel cell stack with an at least partial circulation (7, 9) of the fuel, according to the invention a means is arranged in this circulation for reducing the concentration of an undesired byproduct. This means is comprised especially of a further electrochemical cell (8) to which electric current is applied and which at least partly transforms the byproducts by an electrochemical reduction reaction again to methanol and water. Since the concentration of byproducts is small, the loss in electric current required for the additional reduction reaction has no noticeable effect on the efficiency of the fuel cell stack.

摘要： A high-temperature polymer electrolyte membrane fuel cell stack has at least two high-temperature polymer electrolyte membrane fuel cells (HT-PEFC), which comprise at least one means for determining the CO2 concentration of the cathode waste gas. A method for checking this fuel cell stack is thus possible, wherein at least the CO2 concentration of the cathode waste gas is determined. Optionally, the CO2 concentration of the oxidizing agent that is supplied can also be determined. The CO2 concentration is advantageously conducted in the region of individual cells or cell sections. This can be done, for example, by way of a displaceable lance in the cathode waste gas channel or a plurality of outlets (valves) in the cathode waste gas channel. If a threshold value defining the normal state of functional individual cells is exceeded, appropriate measures can be initiated, such as switching off the entire stack and optionally replacing cells or cell blocks. For more precise information, according to the invention the CO2 concentration of the cathode waste gas is determined not only overall, but also at the outlets of individual cells or cell sections within the manifold.
摘要翻译：高温聚合物电解质膜燃料电池堆具有至少两个高温聚合物电解质膜燃料电池（HT-PEFC），其包括用于确定阴极废气的CO 2浓度的至少一种装置。因此，检查该燃料电池堆的方法是可能的，其中至少确定阴极废气的CO 2浓度。任选地，也可以确定供给的氧化剂的CO 2浓度。 CO 2浓度有利地在单个细胞或细胞部分的区域中进行。这可以例如通过阴极废气通道中的可移位喷枪或阴极废气通道中的多个出口（阀）来实现。如果超过定义功能单个单元的正常状态的阈值，则可以启动适当的测量，例如关闭整个堆栈并且可选地替换单元或单元块。为了更精确的信息，根据本发明，阴极废气的CO 2浓度不仅在整体上确定，而且在歧管内的单个电池或电池部分的出口处也被确定。

摘要： The invention relates to a low-temperature fuel cell stack comprising a specific device for the supply of fuel. Said low-temperature fuel cell stack is characterised in that, in addition to the central fuel supply device, it comprises a supply or storage device for a liquid fuel, and a plurality of separately controllable dosing devices that lead into the central fuel supply device, especially respectively upstream of a distribution channel to the individual cells. Controllable valves, controllable piezoelectric pumps or thermally controllable supply elements are suitable as dosing devices.
