摘要
A standard mechanical engineering mass transfer analysis is adapted to obtain performance calculations for the cathode of a typical polymer electrolyte membrane fuel cell. Mathematical details are provided and sample calculations performed, based on a number of simplifying assumptions. The relative advantages of low and high-mass transfer formulations are critically appraised and compared to a highly-simplified method. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
