Abstract

"áNODO PARA CéLULA A COMBUSTìVEL BASEADO EM MICROTUBOS COM PAREDES POROSAS NANOESTRUTURADAS A BASE DE CARBONO PARCIALMENTE IMPREGNADAS DE IONÈMERO". O presente pedido refere-se a um ânodo para célula a combustível baseado em microtubos com paredes porosas nanoeshuturadas a base de carbono parcialmente impregnadas de ionómero caracterizado pela presença de tubos microscópicos, adequadamente agregados, contendo catalisador, de parede de material condutivo a base de carbono altamente poroso de textura de dimensões de nanómetros como nanotubos de carbono, fios grafitados entrelaçados ou espumas, que recebem na região mais interna de suas paredes uma barreira de ionómero, e que tem eletrólitos líquidos eventualmente iguais, tanto dentro dos tubo, como eventualmente na zona externa de suas paredes. lonómero insuficiente para preencher todo o volume das paredes porosas do arranjo, pode ser aplicado via soluçâo à estrutura de microtubos de parede porosa nanoestruturada de material condutor elétrico a base de carbono, e ao secar formará zonas tubulares apenas na região central dos microtubos, sendo opcionalmente refundido para controle de poros. Catalisadores podem ser aplicados a todo sistema tubular, apenas a zonas sem ionómero, ou apenas sob este. A solução proposta tem diversas vantagens no que se refere durabilidade a cartas mecânicas, baixa resistividade iónica, versatilidade de combustíveis e proteção a envenenamento do catalisador."FUEL CELL-BASED ANODE BASED ON PARTIALLY IMPREGNATED CARBON-BASED NON-RESTORED CARBON WALLS". The present application concerns a fuel cell anode based on partially ionomer-impregnated, carbon-based, nanostructured porous-wall microtubes characterized by the presence of suitably aggregated, catalyst-containing, microscopic tubes of carbon-based conductive material wall highly porous nanometer-sized texture such as carbon nanotubes, intertwined graffiti wires or foams, which receive an ionomer barrier in the innermost region of their walls, and which eventually have equal liquid electrolytes both inside the tubes and eventually in the zone. external of its walls. Insufficient lonomer to fill the entire porous wall of the array, it can be applied via solution to the nanostructured porous wall microtube structure of carbon-based electrical conductive material, and when drying it will form tubular zones only in the central region of the microtubes, and optionally remelted for pore control. Catalysts can be applied to the entire tubular system, only to zones without ionomer, or just under it. The proposed solution has several advantages in terms of mechanical chart durability, low ion resistivity, fuel versatility and catalyst poisoning protection.
