example, in the polymer electrolyte fuel cell the catalytic and intermediate layers both have to
be no thicker than 1 – 3 μm. For preparation of this structure the consumption of SWNT
material pro unit area of the electrode would be no more than ~ 0.5 mg/cm 2 . Even if the high
purity SWNTs produced by the arc technology (at the price of ~ 100 $/g) are used, the price
of the catalytic and intermediate layers would be ~ 0,05 $/см 2 . For comparison, the carbon
paper produced by Ballard Co., USA, is widely used as the gas diffusion layer, and provides
the same contribution to the cost of the layer ~ 0,05 $/cm 2 .
