摘要： The invention relates to a bipolar plate for a fuel cell, especially a low temperature fuel cell comprising a centre plate, at least one intermediate plate comprising a recess for the flow distribution of an operating medium and at least one cover plate which is adjacent thereto and which has at least one recess. The centre plate and the cover plates can be made of metal, plastic or graphite. Additional network-type distributor structures arranged in the intermediate plate between the centre plate and the cover plate and the flow channels arranged in the cover plate advantageously improve the flow within the bipolar plate. The cover plate advantageously prevents the membrane-electrolyte-unit (MEA) from pressing into the bipolar plate. The inventive modular bipolar plate enables an extremely compact structure to be obtained. Space-saving fuel cell stacks can be obtained, wherein the layer thickness of an individual bipolar plate (centre plate, two intermediate plates, two cover plates) is as a rule significantly less than 1.4 mm, advantageously less than 1.0 mm.

摘要： The invention relates to a cooling cell for a fuel cell with an electrical insulation which is disposed on at least one part of the inner surface of the cooling cell. Said insulation between the cooling medium and the cooling cell regularly prevents an undesired flow of current between the cooling cell (or the cooling medium) and an adjacent fuel cell, which are regularly insulated in a non-electrical manner from each other such that normal tap water, i.e. conductive water, can also be used in an advantageous manner as a cooling medium for the inventive fuel cell. The insulation can be created by applying a film or a polymer coating. It is also possible to add insulating agents to the cooling medium, which are independently deposited on the inner surface when the cooling cell starts operating, thereby creating an electrical insulation.

摘要： The invention relates to a bipolar plate for a fuel cell, in particular for a low-temperature fuel-cell, which in addition to a distribution channel (3) and a supply channel (1) and discharge channel (2), which open into said distribution channel, also has an additional supply channel (4), which is used to supply an operating medium directly to the distribution channel (3). This promotes improved flow guidance for the operating medium. The distribution channel area, in which the adjoining membrane is in danger of drying out as a result of the low humidity of the operating medium, is minimised in a uniform manner and the yield of product water that is formed is significantly increased.

摘要： Disclosed is a cooling element for use in a polymer electrolyte fuel cell (PEFC), especially a high-temperature PEFC. Said cooling element is monolithically designed and has a comb-type structure. The recesses between the ribs of the cooling element are used for accepting individual fuel cells parallel to one another. Matching openings in the individual fuel cells that are to be inserted into the recesses and the ribs of the cooling element allow for a continuous conduit system for delivering and discharging the operating material. The cooling element further comprises a continuous conduit system along the stack axis in order to conduct a coolant therethrough. Said conduit system is entirely disconnected from the conduit system for the operating material such that advantageously, the coolant circuit is not affected when individual fuel cells are replaced. Advantageously, current bridges can be mounted on the ribs of the cooling element in order to transmit the current between the individual cells.

摘要： The low-temperature fuel cell has a line (6) between the cathode chamber (3) and the anode chamber (1) for recirculating water located in the cathode chamber into the anode chamber. Eduction is caused by a light overpressure in the cathode side. Said overpressure can be applied permanently or just temporarily. By evacuating the gas formed in the anode chamber, for instance CO2, the required pressure difference can be advantageously produced in a direct methanol fuel cell. In an advantageous embodiment of the low-temperature fuel cell, a non-return valve (7) is provided in the recirculation line. This simple configuration has very positive results in a fuel cell stack.

摘要： The invention relates to a direct methanol fuel cell stack with an at least partial fuel circuit. According to the invention, a means is disposed inside said circuit for reducing the concentration of undesirable by-products. Said means particularly consists of another electrochemical cell to which a current is applied and which re-converts at least partially said by-products into water and methanol by means of an electrochemical reduction reaction. Since the concentration of by-products is small, the loss of current which is required for the additional reduction reaction does not lead to a significant drop in the efficiency of the fuel cell stack.

摘要： The invention relates to a low-temperature fuel-cell stack, comprising a first, last and at least one central, serially connected fuel cell respectively provided with a distributor structure for distributing operating substances. According to the invention, the first and last fuel cells are provided with a distributor structure respectively providing for a volume flow of operating substances when the fuel cell stack is in operation, said flow of fuel deviating from that of the central fuel cell by at least 30 %, thereby making it possible to ensure an approximately even temperature distribution inside the entire stack during operation of said fuel cell stack, advantageously resulting in an approximately the same flow density distribution and therefore in a regular increase in the performance of the entire fuel cell stack. When pre-warmed operating substances are used, especially a pre-warmed educt, significantly more operating substances flow through the first and last cells than through the central cells.

摘要： The invention concerns an electrolytic polymer membrane fuel cell wherein the oxidizing agent is supplied to the cathode physically dissolved in a liquid. An enrichment unit external to the fuel cell serves to physically dissolve, at least partly, the oxidizing agent in an adapted liquid, in normal or low excess pressure conditions. Thus it is possible to reduce the compression power on the cathode side. In a particular embodiment, said liquid is not miscible with water such that the water produced on the cathode side can be simply extracted from the cathode region as a second phase, and then separated. The liquid flowing through the cathode is much more adapted than a gas for collecting the heat produced in the fuel cell, and for simply evacuating the liquid outside the fuel cell. Since said liquid does not react either with water or with the oxidizing agent, it can advantageously be circulated.
