摘要： The invention relates to a fuel cell stack, whereby a regulation of the operational medium concentration may be effected by simple means. It is thus possible to automatically operate the fuel cell stack almost optimally, which means just above the minimum necessary operating medium concentration for operation, dependant upon the load. The invention is based upon the effect that an individual fuel cell under identical operating conditions produces a lesser cell voltage. The above is used as the adjustment parameter for the controlled addition of at least one operating medium, for example methanol or also air. According o the invention, the fuel cell stack can thus be operated with economical means at nearly optimal conditions.

摘要： The invention relates to a bipolar plate for application in a fuel cell, comprising a channel forming structure. The bipolar plate further comprises, at least partly, a porous region, which borders a formed channel. According to the invention, in a fuel cell with the above bipolar plate, an improved distribution of the operating material under differing load conditions ( high and low throughflow) with reduced pressure loss is made possible by means of the combination of channels and open pores within the porous region. The above regularly leads to an improved efficiency for the fuel cell.

摘要： The invention relates to several cells for current generation, especially fuel cells that are connected in series. Diodes are connected in parallel to said fuel cells in such a way that current (I) generated by the fuel cells cannot cause any short circuit. If one of the cells fails as a result of a defect, the current flows through a parallel-connected diode due to the fact that the diodes then form the low ohmic resistance. In case of a failure, this makes it possible to automatically short-circuit the defective cells in a simple and economical manner.

摘要： The invention concerns a fuel cell comprising an anode, an ion-conducting electrolyte and a cathode. A barrier layer located on the cell anode side separates the fuels from the electrolyte and is permeable to atomic or molecular hydrogen. Means for reforming the fuel, for example in the form of a copper/zinc layer, is placed adjacent to the barrier layer. Said cell further comprises means oxidising the hydrogen passing through the barrier layer (protons generally). Unlike other fuel cells with direct methanol oxidation, it is possible to use any electrolytic material since it is no longer necessary to take into account the fuel chemical compatibility with the electrolytic material. The cell preserves its efficiency as, for example, the methanol cannot reach the cathode and poison the latter. Moreover, the reforming process can be carried out at relatively low temperatures, since the hydrogen produced is permanently withdrawn from the reforming reaction.

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： 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： The aim of the invention is to remove the excess heat from one of the fuel cells by means of evaporating the product water into steam and the flushing of said steam from the system by means of the oxidizing agent. The fuel cell system further comprises in addition to at least one fuel cell, a downstream evaporative cooler arranged before the cathode and after the anode and which is connected to the condenser for water supply. In order to increase the efficiency of the system a fuel cell stack is advantageously applied. The depleted feedstock emerging from the anode chamber is fed to an evaporative cooler which is also supplied with an oxidising agent and water from a condenser. The heat of the depleted feedstock is transferred to the introduced water in the evaporative cooler which is transformed into steam and taken up by the oxidising agent which is also heated. The mixture of oxidising agent and steam is removed from the evaporative cooler and at least partly recycled to the cathode of the fuel cell. The remaining fraction is released to the environment.

摘要： One disadvantage of known fuel cell electrolyte layers is that they do not only let hydrogen ions (protons) through but do the same in part with regard to hydrate sheaths or a part of the fuel. In methanol driven fuel cells the electrolyte enables methanol molecules to pass through. The problem is solved by an electrode-electrolyte unit wherein the electrolyte is divided up into two electrolyte layers (4, 6) with a blocking layer (5) in between. The blocking layer is made from a non-porous or closed pore material which absorbs protons on one side, emits them on the opposite side and is impervious to all other substances. Preferably, the blocking layer (5) is made from a palladium silver alloy. The electrode-electrolyte unit is suitable for fuel cells involving the use of a fuel whose protons can be catalytically separated on the anode, e.g. hydrogen or methanol.
