摘要

"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.
