| 摘要 |
The invention relates to a fuel cell unit for producing a continuous current by converting chemical energy, using an electrolyte which supports an anode and a cathode separately from each other. Said fuel cell unit has a self-supporting hollow microfibre-matrix electrolyte (2). Said hollow microfibres have a wall thickness of approximately 0.01 to 50 mu m and an equivalent diameter of approximately 0.05 to 280 mu m. The hollow microfibres are arranged in the form of bonded filament or filament yarn fabrics, in which case the ends (3) of the hollow microfibre are bonded in such a way that they are dimensionally stable and are left at least partially free to allow access to the lumen of the hollow fibre, or bonded staple fibre or staple fibre yarn fabrics, in which case the hollow microfibre ends (3) are bound in such a way that they are dimensionally stable. The invention also relates to a fuel cell stack (1) made up of several fuel cell units of this type, and to the use of a fuel cell unit of this type. |
