Preparation and evaluation of electrocatelysts for phosphoric acid fuel cells
Highly dispersed platinum has been placed on carbon supports so that they may be used as phosphoric acid fuel cell electrocatalysts. These catalysts were characterized for both the platinum surface areas and crystallite sizes. For a given carbon impregnation technique with the noble metal salt, a definite correlation between the specific surface area of the derived platinum crystallites to the BET surface area of the carbon support was found.
