摘要： Fuel cell stack with several individual cells, arranged one over the other, with electrochemically active layers, the first surface of which is exposed to fuel gas, introduced from one side of the stack and the other surface is exposed to oxygen, preferably introduced from the other side of the stack, whereby the corresponding tail gases are collected on the opposing side of the stack. An electrochemically inactive cell structure is included at at least one end of the stack, through which said reactants flow on operation of the fuel cell. A heating element for catalytic combustion of the fuel gas for the fuel gas cell is preferably embodied by the electrochemically-inactive cell structure. The electrochemically inactive cell structure and/or the heating element embodied therein can be embodied such that the heating power within the operating temperature range of the fuel cell is significantly less at cold temperatures. The construction of the electrochemically inactive cell structures(s) is similar to the electrochemically active individual cells with regard to the flow characteristics thereof.

摘要： The invention relates to a fuel cell comprising a cathode-electrolyte-anode unit (7) and a structure which distributes the combustible gas across the electrode surface thereof. The surface of said structure, which faces the electrode (7A), is formed by a perforated film (1). The longitudinal axes (2a, 2a') of at least some of the holes (2, 2') or passage openings forming the perforation are differently inclined relative to the surface of the film such that the outlet port (2c) of the holes (2), which faces the electrode (7A), is preferably at least slightly directed towards the discharge (8A) side of the combustible gas from the fuel cell on the intake side (8Z) of the combustible gas into the fuel cell while the inlet port (2c') of the holes (2'), which faces the electrode (7A), is preferably at least slightly directed towards the intake side (8Z) of the combustible gas into the fuel cell on the discharge side (8A) of the combustible gas from the fuel cell. Alternatively, holes (2, 2') can be arranged essentially next to each other within the film (1), the inlet port (2b) of said holes (2, 2'), which lies opposite the electrode (7A), being alternatingly directed towards the combustible gas intake side (8Z) and towards the combustible gas discharge side (8A).

摘要： The invention relates to a fuel cell and to a method for producing such a fuel cell. For producing a single fuel cell, a knitted material (10) or a similar porous support structure such as for example a woven, interlaced or interwoven material is produced from one or more metal wires (12) and a cathode-electrolyte-anode unit (CEA) is applied thereto in layers or steps. The single cells are combined to give a fuel cell stack but are separated from one another by bipolar plates (14). By embodying the support structure (10) as described in detail, it is possible to create locally different flow resistances in said structure, thereby influencing the reaction process in the single fuel cell as desired.
