ABSTRACT:
A method of continuously manufacturing strips which include at least one thin porous conductive layer, said strips being intended in particular to form electrodes for fuel cells, in which method one stage in the manufacture of said layer includes passing powdered material to form it between the rolls of a calender. The method, said material is prepared by mixing an aqueous dispersion of carbon powder, which is possibly coated with a catalyst, with an emulsion of binder; precipitating the binder on the powder; drying and dry crushing the precipitate then wetting the powder while crushing is continued, with a liquid intended to prevent the grains from adhering to the rolls of the calender while lubricating said grains material thus obtained, being free from any pore-forming product, is calendered without using any support.
