摘要

COMPOSITION OF GAS FLOW DISTRIBUTOR PLATE FOR FUEL CELLS, FUEL CELL AND MANUFACTURING PROCESS OF GAS FLOW DISTRIBUTOR PLATE. The present invention relates to a fuel cell gas distributor plate composition comprising: (i) a base composite formed of binders, graphite filler and additives; and (ii) nanotubes and / or carbon fibers added and mixed to the base composite in an amount ranging from 0.3 to 10% by weight. Also described is a process for manufacturing gas flow distributor plate for fuel cells comprising the following steps: (a) forming a base composite from the addition of graphite filler binders and additives; (b) Addition of nanotubes and / or carbon fibers to the base composite in an amount ranging from 0.3 to 10% by weight; and c) Conformation of the base composite with nanotubes and / or carbon fibers in gas flow distributor plates. further described is a fuel cell comprising at least two plates or a plurality of gas flow distributing plates comprising a composition formed of a base composite formed of binders, graphite filler and additives; and nanotubes and / or carbon fibers added and mixed to the base composite in an amount ranging from 0.3 to 10% by weight, these plates being obtained by the process of manufacturing fuel cell gas flow plate.
