The present model appears to be useful in the design of fluidized bed filters. It does not address questions concerning the quality of fluidization, stickiness of the particles, solids regeneration rates and agglomeration effects. In order to optimize the fluidized bed filter these effects must be considered in conjunction with those aspects to the problem elucidated here.

The equation is a linear one if parameters (as a first rough approximation) are considered constant with 0. The equation does not take into account the agglomeration effects which are an increasing function of 0. Agglomerates are weak points in the materials and act as strong stress concentrators. The linear... 

Looking at Fig, 4 we see a qualitative agreement of the experimental data with equation (4) in the case of untreated and ITS treated beads for SIC treated beads, after an initial small increase of Oy, we observe a decrement which may be related to agglomeration effects.

As for the first assumption, the electrolyte phase must be treated as a mixed phase. It consists of a thin-film structure of ionomer at the surface of Pt/C agglomerates and of water in ionomer-free intra-agglomerate pores. The proton density is highest at the ionomer film (pH 1 or smaller), and it is much smaller in water-filled pores (pH > 3). However, the proton density distribution is not incorporated in the statistical utilization Tstat, but in an agglomerate effectiveness factor, defined in the section Hierarchical Model of CCL Operation. ... 

In the hierarchical model, macroscale transport processes will be coupled to transport and reaction at the mesoscale, as illustrated in Figure 4.1 an explicit treatment of agglomerate effects is needed to properly assess the effectiveness factor of Pt utilization, which transpires as the key parameter in the structural optimization of CCLs.
