(WO9934464-A2)   NOVELTY - A fuel cell unit has a hollow micro-fiber matrix electrolyte, in which the micro-fibers (2) are filament or staple fiber bundles with bonded ends.    USE - The fuel cell unit or stack is used for d.c. generation from cross-flow streams of fuel (especially a hydrogen-containing fuel) and an oxidant (claimed). The fuel injection nozzle is used in the fuel cell unit or stack (claimed) or in Otto or diesel engines, in Carnot cycle processes or the like.    ADVANTAGE - The fuel cell unit has a large reactive surface area at minimum space (e.g. 11000 cm2 per cm3 fuel cell volume), is simple to produce and has high flexibility of use    (ZA9811899-A)   NOVELTY - A fuel cell unit has a hollow micro-fiber matrix electrolyte, in which the micro-fibers (2) are filament or staple fiber bundles with bonded ends.
