Modeling the internal structures of the catalyst layer. — The cells with acetylene blacks gave good performance in our study of the carbon supports.4 The specific pore volume distributions of the

M&E assemblies with various acetylene blacks are shown in Fig. 1.AB is commercial acetylene black and the others are experimental ones. The peak diameters of the pores of M&E assemblies with AB2, AB3, and AB were ranged from 0.04 to 1.0 pm where the PFSI was distributed. 1 And those with AB1 and AB18 were on the boundary and out of the range, respectively. Peak diameter depends on the size of the pores formed on and between the primary particles in the i
