Published: Epting and Litster on Size Distributions and the Agglomerate Model
In this spring of 2012, the International Journal of Hydrogen Energy published a new paper by TPES researchers Billy Epting and Shawn Litster, titled "Effects of an Agglomerate Size Distribution on the PEFC Agglomerate Model." The work examines an aspect of the popular agglomerate model of PEFC electrodes - namely, the impact of an agglomerate size distribution in place of the usual assumption of a single, representative agglomerate size.
Epting and Litster modified the agglomerate model's equations to incorporate the agglomerate size distribution measured in recent TPES XCT work. They found that even if a smaller agglomerate size is chosen, the accuracy of the model (with respect to the model with a variable agglomerate size) depends on overpotential.
