greater hydraulic resistance in the electrolyte feed tubes. It should be emphasized that these tests are not absolute measurements of permea bility but rather reflect only differences between the various materials. This is due in part to the fact that a wetting time of only one hour was employed. It is not presently known to what extent battery cycling affects wetting or porous graphite. However, it is believed to be significant. The relative contributions of wetting and physical alteration in activated porous graphite to the change in permeability of the material are not known. Minor variations in permeability as mentioned above presently are not thought to be a major consideration that should seriously affect the qualification of a porous graphite material.

Refer to Figure 35-3. Comparison of Candidate Porous Graphites After activation each of the graphites tested has demonstrated similar voltaic per formance capability at foreseen operating current densities. With the exception of graphite 19C, the electrolyte pressure drops are equivalent to that of graphite PG-60. Although the pressure drop value of 19C is 50% greater than that of PG-60, it re mains within the acceptable range. 35-9PDF Image | Development of the Zinc-Chlorine Battery for Utility
