Effective catalyst layer Knudsen diffusion

In Example 5.8, we solved for the mass transport limiting current density of an electrode based on the resistance to gas-phase transport only. In the PEFC and some other fuel cells, a thin layer of liquid or ionomer may cover portions of the catalyst surface, resulting in an additional film resistance. Symbolically show this simation to form a more precise model of mass transfer limited current density at an electrode. Ignore convective effects and Knudsen diffusion in this problem. [Pg.231]
